They come across a young woman struggling in the water, and cole dives in to save her. However it ends up being a trick as all of the Gangs ends up getting captured by a net, lifted up and out of the water. They are brought down on the deck of another ship, where isabella and a pretty lady in a pilot's uniform stands. She introduces herself as lina as the girl introduces herself as Lilly, and they are the Two sins fighter girls. They declare they will become the greatest fighters in the world and steal the Crystal Clock lullaby from enchated wonderland portal, which lloyd explains is one of the greatest artifacts in the world.
darlyn asks lina about the Wedding firework, which their queen replies was taken by the League of the evil sins. He shows the wanted posters of Sull khan naar aka Edward, God/goddess of game and Thier minions, Evil peacock lady, Thomas gray, and turbo/king candy to them. They then find a fleet of ships coming toward them, the fleet of the The league of the evil sins. In the crow's nest of one of the ships is Goddess of game completely swimsuit taking a bath. Sull khan naar then jumps out and declares that their boss, Turbo/king candy, will become the Sins King. Sull khan naar, god of game and goddes of game order an attack, so the knights of the League of the evil sins start leaping down to attack the teammtes crew and friends. The Heroes manage to fight them off, but Sull khan naar himself leaps down, curling up and becoming a big spiky vines rope whip on his arm.
emmet,dipper,maple,jake and finn places thier wedding ceremonies clothes on Kai's arm as they gets ready to fight. stan declares his plan, "Running is Winning", and has their boat flee from the League of the evil sins' fleet. In the chaos, the Two sins fighter girls lose a small box, so detective emliy leaps into the water after it as lina whacks stan in the head to stop him. emily retrieves the small box, but sull khan naar, God and goddess of game arrives, standing on the back of Spike vines ball in the water, and Sull khan naar hurls bombs at the boat, blowing it apart. Sull khan naar,god/goddes of game kidnap kai, as They are a great sins, and throw another bomb to make their getaway. darlyn and lloyd sinks below the ocean's surface, but cole manages to retrieve them.
The remaining teammates crew huddle aboard the wreckage with the two sins fighter girls and the Detective patrol, with emily deploying a parachute as a makeshift sail. jay blames Emily's going after the music box for the reason Kai was kidnapped, but emily explains that it is the only thing lina has left of their hometown. A brief flashback shows how when a man found lilly and lina, the lullaby of the music box was all that could calm them down. darlyn asks if that means they are not families, but emily replies that they are friends even if not through blood. As they sail along, dipper spots a whirlpool, and emily says that it means they are coming close to enchated wonderland portal. On enchated Kingdom, in a great castle, Turbo/king candy sits on his throne with his daughter katty while two couples explain the situation to them. They say the weapon of mass destruction he is having them build has spilled too much blood, but Turbo/king candy does not care and orders them back to work, as he will need the weapon to conquer the seas and become Sins King. sull khan naar and god/goddess of game come into the room carrying Kai, and Peacock lady looks all over Kai creepily. Turbo/king candy asks if kai will be katty's husband, and he glares at her, so Turbo/king candy says that he is katty's type. Kai tells Turbo/king candy that he cannot stand bad hair girl, so Turbo/king candy offers to comb on his dughter's hair, but then says that he hates weak girl more, doubting that Turbo/king candy could beat Darlene maylee "darlyn mae" p. De guzman. God/goddess of game and Sull khan naar show Turbo/king candy the wanted poster of emily potter, and thomas gray says that zane must be with him too. Turbo/king candy declares that he will kill Mae and emily and use his bounty to fund his daughter wedding with Kai by removing his memories with sins amnesia, which used by charles Dalimar and his son victor.
In hospital, kai wake up in room, when he meet the nurse asks your names which ka don't remember his memories, when the nurse will help him to get his new names, after his memories was remove, in outside the doctor said Just find the names, so kai say goodbye to them, but suddenly he got abducted and kidnapped by two lego raper girl sandra and patty who search people for tries to remove demon curse, while ripping kai's clothes and rape him, at until kai was tunred into demon beast which attack two girl and he escape the old house to survives armies attack kai who goes into the house of the roget family which they tries to help kai, but until marie roget turned into a ghost causing kai turned back into human, naked and the family help kai by cover with towel, in the house kai wake up and put the clothes and asks the marie will gives him a new name, gemshot and do some fun for gemshot, one month later, gemshot visit to house where marie roget is killed as gemshot must avenge on her and goes to evil sins castle.
Meanwhile, the remaining Heroes and Friends arrive on Enchatedwonderland portal, and immediately start heading up the winding stairs to the town that is at the top. The way is laden with traps, though, and the stairs turn to a ramp as they start to slide down, water rushing toward them. Darlyn grabs on and uses her magic chain rope powers to stop them from being skewered upon spikes, and as boulders come rolling toward them cole leaps from wall to wall, kicking them away. zane reaches down and tears up the floor so that they can walk up the path to the top. They arrive at Enchatedwonderland Kingdom, a fun place with windmills everywhere, and a large tower, Evil sins Castle, is in the center. At the top of the tower finn can spot the wedding firework. The four decide they will get new clothes and grab a bite to eat before rescuing Kai, much to Emily's shock.
jay, zane, and cole get new clothes that are much easier to move in, and the group heads into a sort of shop. darlyn and lloyd says Clockwork Town is fun, but the two couple at the shop disagree. They explain that they created the Crystal Clock lullaby, but ever since, they have been suffering since the League of the evil sins arrived. Ever since, they have been creating killing weapons instead. emily declares that the heroes will defeat the League of the evil sins, but they object, as they have not agreed to anything yet. jay says emily just wants this because the Crystal Clock lullaby will be easier to steal without the League of the evil sins around. The couple say it will probably be better if the Crystal Clock lullaby is taken away. darlyn then says that you cannot make a fortune without risking your life, so they decide to set out. As the group leaves, the couple find a music box on the ground, realizing that the girls was lily and lina.
In Evil sins Castle, the lover teammates crew arrives and angela sees kai beats the League of the evil sins at poker. Peacock lady gets up and walks away, dropping off her cape and turning into peacock as she slides into a pipe. Sull khan naar decides to go too, wheeling off down a rope. Outside, the heroes and friends are hauled up in a small basket along a rope, high above EnchatedWonderland Kingdom, toward League of the evil sins. emmet notes that the windmills below look just like his windmill, and he takes it out and finds it is broken. dipper quickly fixes it. Suddenly, Peacock lady forms before them, and Sull khan naar arrives as well, tossing her cape to her.
Peacock lady declares she has eaten the 600 lives, and so Sull khan naar throws balls at them. cole leaps out to kick him away, but spikes vines protrude from Sull khan naar's ball, piercing right through Cole's foot. cole screams and cries out in pain as he starts to fall. emily catches him only to drop him when Goddess of game arrives and floods their airship. cole then falls and hits the ground, hard. A mine then nearly blows cole up. He is then quickly tied up by Peacock lady,goddess of game and sull khan naar and brought to Evil sins Castle. cole is dumped before them, and Turbo/king candy says he did not kill cole because he is kira's boyfriend. gemshot proceeds to deny caring for him anymore.Turbo/king candy then sends God of game his minions to get rid of the rest of the crew.
Meanwhile, at the gate to Evil sins Castle, the group, minus cole, has arrived and lilly and lina goes on about how if he was captured, emily would save him no matter what, and the others see that emily has a metal hand. This irritates jay, who says that it does not matter at sea, and how he hates people who depend on others to save them. darlyn then says it's time to get going, and whe tells lina to stay behind if she's afraid. She uses element echo fist to knock down the door, and they charges in, but is quickly mobbed by a huge group of knights. zane runs in after the, to help. Meanwhile, back in Evil sins Castle, thomas gray notes how zane finally arrived.
Suddenly several villain, formerly under Victor, arrive with the King Cannon, which is now completed. They dance, proclaiming about how much better Turbo/king candy is than charles. cole apologizes to kira about how he could not do anything because he wanted to use only his own strength to show off to her. Turbo/king candy interrupts, demanding what Cole's relationship with his "fiance" is, and cole replies that he "adoptive kai as his classmate/brother". This makes Turbo/king candy angry, and after beating cole up declares that he will have cole crucified.
Down below, teammates crew fight through the knights when God of game and his minions arrives, standing on a tall pole. He points them toward cole, who is hanging from a cross up high outside the castle, and so the old man unleashes a cloud of poison snow, snow that will make those who inhale it paralyzed. As Their strength start to fail, jau turns to lilly and lina,declaring how brave he can truly be. jay scales the pole and grabs Old man around the legs, holding the flap that releases the snow shut, yelling for the others to go on ahead. God of game becomes furious, trying to help old man to shake jay off, and jay has to put his mouth over the poison snow release to keep the snow from coming out. The others see Jay's diversion and so they rush on ahead as Old man launches into the air with jay along. He lands on the balcony of Evil sins Castle, and jay collapses, filled with the poisonous snow. Turbo/king candy declares that jay will be crucified as well, and he is put up on a cross beside cole as nya looks on in despair.
The heroes and friends rush up the stairs of the castle, fighting through the enemy knights, but as they near the top they come to a chamber where the floor and ceiling close in on them. The teammates crew struggle to hold it up as lilly and lina is knocked out, and emily takes lilly and lina to safety. isabella reveals that emily was the one to steal the Wedding fireworks, as she wanted to bring the Heroes to Enchatedwonderland Portal. zane blames it on Isabella's greed for the Crystal Clock lullaby, but Isabella replies that she wanted the League of the evil sins defeated by emily so the island could be free and lilly and lina could meet their family, as Enchatedwonderland portal is their home.
Isabella kidnap emily and rushes ahead to face the Leauge of the evil sins, leaving The heroes to their fate. Thomas gray then arrives, drawing his sword and saying how zane gave him the scar he has across his face. zane replies that he does not remember Thomas gray, so Thomas gray becomes angry, using Hari Hari Ken (Sword of Blood ruby) to stick Zane full of poison. zane falls to one knee, as the potion were tipped with God of game's poison. zane tells Darlyn and lloyd to hold on a little longer as he draws his sword and charges at Thomas gray, but a fence comes up in front of Thomas gray, causing Zane to only slash it instead. Thomas gray jabs his sword through the fence, getting Zane in the midsection, and so he carries away the injured zane on the lift, where he is brought to Turbo/king candy to be crucified.
At the top floor of the castle, zane, cole, and jay hang bound to crosses as turbo/king candy readies to King Cannon to blow them all apart. He says that angela must be overjoyed, but angela aims a kick at Turbo/king candy, snapping how she'd rather die with her friends then kai marry katty. Turbo/king candy strikes her across the face and rip angela's clothes, saying it can be arranged, and so gemshot (kai) and angela is set up to be killed as well. Down below, lily and lina wakes up to see the heroes struggling under the ceiling, asking where Isabella and emily went. darlyn explains emily and Isabella went to fight the League of the evil sins, so lily and lina runs up the stairs after them, much to their dismay. Meanwhile, turbo/king candy fires up the King Cannon, but before he can fire, a large metal wall comes up, with isabella and emily standing before it. Emily walks forward with dynamite strapped to her midsection, and Isabella holds a lighter, ready to sacrifice emily for the island. Turbo/king candy only laughs, stepping forward as he says that detonating the dynamite will only destroy the portal's key, which is below his feet, within the castle. If the island key is destroyed, the whole island will be destroyed as well.
Isabella fleas away Before emily can react, turbo/king candy starts tossing her around like a rag doll, knocking the dynamite off of her. lina tries in vain to help their friends. As emily hits the floor, Thomas gray picks him up angrily after emily corrects him on a misspoken word (Thomas gray misspeaks many times throughout the movie). lily and lina then tries to defend emily. Meanwhile down below, emmet sees that his windmill toy, which dipper kept after fixing it, is broken, so with great fury he pushes up the ceiling, forcing themselves up and through the floor of the throne room where the League of the evil sins are.
As everyone gapes in shock, gemshot picks up a stick of dynamite, notes how cool it is, and lights it. Everyone freaks out for gemshot to throw it away, so gemshot tosses it to the iron wall in front of their friends. It blows the iron wall to pieces, and Gemshot asks where the strangers are, which the Emily and friends reply to that he just blew them up. However, cole, zane, and jay emerge from the smoke, albeit somewhat battered.
With the three now free, the League of the evil sins burst into action. God/goddess of game their minions chases alice,her friends and jay up to the roof of the castle. lina and cole and Sull khan naar square off, and Sull khan naar laughs that cole will not be able to kick him with his bleeding feet. jay tosses down Cole's zx suit to him, and cole puts them on, but sull khan naar refuses to believe they will make a difference. jay shoots Lumber jack in the face with a Holy water Star, and as God /goddess of game goes down he tosses Zane's weapon and zx suit down to him. zane catches them and barely blocks Thomas gray's sword, who took a stab at his back. zane stands in front of pixal, defending her. Turbo/king candy and darlyn begin their fight, as darlyn uses Fire lighting fist, but finds it has no effect. Turbo/king candy declares that his body is as strong as steel because he ate the 900 lives.
The lover teammates crew fleas away as sull khan naar curls up into a vines whip and charges at cole, but cole sends him careening into the roof with one kick. cole leaps up and proceeds to kick sull khan naar, several more times until he drives Sull khan naar down through the floor, into the island key chamber. He again drives sull khan naar into the ground, and cole stands victorious, flicking away the trone vines, as sull khan naar lies in a bloody heap. On the balcony, zane tears off his clothes and put them on, assuming his three weapon stance, and he charges at Thomas gray. God/goddess of game and their minions declares to alice, her friends and jay the power of his poison snow, and they charges at they as Alice friends pretends to be frightened and alice and jay tries tofind the way to defeat them. At the last second jay fires his Lighting Star, striking Old man and causing a big explosion. jay,alice and alice friends falls back into the pool below while God/goddess of game and their minions Are sent flying off into oblivion. Floating in the water, jay yells that God/goddess of game and their minions got what was coming to him. darlyn uses Ninja fist Whip on turbo/king candy, but gets all tangled up and is knocked to the floor.
zane and Thomas gray trade sword swings, engaging in a fierce duel. Thomas gray uses Hari Hari Ken once more, but zane blows them back with his swords. He stands back up, and Thomas gray says how he shouldn't be able to stand with all of the poison in his body. zane replies that he cannot fall, because he faces a long journey and there is one man at the end of it for him to beat. zane then uses Oni Giri and takes Thomas gray down. Upon seeing the defeat that the other League of the evil sins endured, Peacock flees, dropping her cape and becoming peacock again, heading into a pipe, but gemshot (kai) grabs the pipe and pours Peacock into a jar, which lloyd screws shut and holds down.
Meanwhile, the fight between darlyn and turbo/king candy continues as turbo/king candy's arm lights with fire. darlyn grabs onto it but is singed. turbo/king candy starts pounding darlyn around, but katty fires a missile from the King Cannon at Her father. turbo/king candy is barely able to avoid it as it smashes through the window and flies out into the sky, landing in the water with a great explosion. katty says that his next shot will not miss.
turbo/king candy becomes furious that his daughter is using his cannon, so he pulls a gun and fires it at him. lily leaps in the way and is shot in the chest, falling to the ground. darlyn becomes furious and throws turbo/king candy through the wall, causing the entire top tower to tip and water to pour down. turbo/king candy emerges, more furious than ever, and he climbs onto the King Cannon and fires it at darlyn. darlyn catches the missile with her magic chain rope, twisting chain ropearound and stretching chain rope way out into the sky, and so she pulls it back in, using Element fist Screw to drive the missile right into turbo/king candy's chest. turbo/king candy is driven through the floor and lands in the island key chamber, where there is a great explosion and the island key is destroyed.
emmet beat charles and victor to get it and tosses Sins amnesia machine to her as congratulations for defeating turbo/king candy. lina kneels beside lily and sees that Lily's chest was protected by a sheet of metal under her dress. As lina carries lily to safety, the Crystal Clock lullaby starts chiming. All of the Heroes and emily as well as lily and lina recognize the sound as Lily and lina's music box. It is then revealed that the two couple they had met earlier were Lily and lina's parents.
The three friends head back down out of the castle to the townspeople of Enchatedwonderland Kingdom, and meet the two couple from before again. The couple explain that lily and lina is their daughter, and a brief flashback shows the mother putting lily and lina into the water, hoping that they will escape and survive.
With the key destroyed, the entire island starts to collapse, and the Airship falls from it and into the ocean. The people of the island land in the water and scramble into the boats as their island is completely gone, but they know it could not be helped and that they will rebuild a new island and a new future.
