Plot
One morning, Lilo and Stitch arrive for hula class after feeding Pudge the fish. Mertle insults Lilo about feeding Pudge again. Moses then explains to both Lilo and Mertle that he'd like for them to just get along with each other. Then he announces that they are on summer break for the month. After the hula class ends Mertle tells Lilo that she and her friends are going on vacation to Honolulu. When Lilo is about to say that Mertle didin't invite her, Mertle says her mom wanted to invite Lilo to come but Mertle doesn't want her to. But Moses tells Mertle it would be a good idea and calls Nani and she agrees to come with them along with Jumba and Pleakley. Then he tells Mertle and her friends to be nice to Lilo and for Lilo to get along with them. Because of that Mertle grumpily agrees.

So they set off on a ferry for Honolulu. When they get there they go to the beach. While Nani and Mertle's Mom are napping Mertle and her friends wander to the rockpools with Lilo and Stitch following them. Where Lilo tries to tell them that they need to stay with the adults. But Mertle doesn't listen. Then they get caught in a high tide and they stumble across the boathouse of Professor MacCrab, an eccentric but kindly marine biologist. Reasoning that climate change will melt the polar icecaps to produce marine transgression within the next century, MacKrill reveals he has developed a potion to transform humans into fish, along with an antidote to reverse the process.

Mistaking it for lemonade, Elena drinks the potion and turns into a starfish, which Mertle unknowingly throws out the window into the sea. Lilo discovers the mistake after Elena's transformation was caught on camera. Lilo, Stitch, the professor, Mertle, Teresa and Yuki set out to find Elena, but their boat sinks in a storm. Lilo, Stitch, Mertle and the two other girls drink the potion, becoming fish too. Lilo a parrotfish, Stitch a pufferfish, Mertle a jellyfish, Teresa a blue tang fish and Yuki a lobster. Nani, Mertle's mom, Juma and Pleakley find out that the kids and Stitch are gone. Noticing footprints in the sand heading to the rockpools, they head to the rockpools to search for them but find only Mertle's sunglasses instead. They fear the worst until Professor MacCrabl, having survived the storm, arrives and shows them the video of Elena's transformation.

Underwater, the leaking antidote attracts a great white shark and a pilot fish. They consume it, gaining intelligence and anthropomorphic appearances. Joe, the pilot fish, quickly uses the antidote to found a civilization of intelligent fish, intending to launch a revolution. The Shark becomes his dim-witted subordinate.

Lilo, Stitch, Mertle and the hula girls reunite, accompanied by Emily, a seahorse who Elena adopts. If they do not find the antidote within forty-eight hours, their transformations will be irreversible. The trio swim to Joe's domain, a sunken oil tanker, where Mertle tries to steal the antidote. They are caught and interrogated by Joe about their intent and origins. He demands they manufacture more of the antidote, or the Shark will eat them. The children are imprisoned, guarded by an aggressive, militaristic king crab. Stitch and Emily free the children, who manage to escape.

The children decide their best hope is to duplicate the antidote's formula themselves if they work together. But Mertle doesn't want to work with Lilo, but the hula girls remind her what Moses said about getting along with each other. And they tell the truth to Mertle that they don't think Lilo is wired but unique, they tell her to put her diffrences with Lilo's diferences aside and work together. Then Mertle agrees to give it a try. They start gathering ingredients from around the ocean. Just as they complete the potion, Joe and his army appear. In a stand-off, Joe drinks the last of the original antidote, transforming his fins into hands. The children try to flee, but Lilo is wounded by the Crab, who drinks the new antidote, declaring himself the King Crab. At the same time, MacCrab and Nani pass over in a makeshift boat powered by a water pump. The pump causes an underwater typhoon, sucking up all the army. The Shark eats the King Crab, but is incapacitated when he is sucked head-first into the pump.

Mertle remembers that MacCrab has another antidote in his laboratory. Formulating a plan, Mertle plans to carry Lilo, Stitch and the hula girls through dangerous seawater intake pipes back to the lab. Elena has to leave Emily behind. The children flood MacCrab's laboratory to reach the potion, but Joe follows, stealing it. Lilo pursues Joe into the pipe, tricking him into repeatedly drinking from the potion by challenging his intellect. Joe evolves into a deformed humanoid and drowns.

Lilo drags the antidote back into the lab, Mertle uncorking it just as Mertle's mom, Jumba and Pleakley open the door to the flooded lab. Mertle, the hula girl and Stitch become human once more, reuniting with Nani, Mertle's mom Jumba, Pleakley and MacCrab. After a few tense moments in which a stuffed fish is mistaken for the limp body of a Lilo, the human Lilo emerges from one of the lab's pipes with a broken leg. Then she goes over to Mertle who tells her her plan was something. Then Mertle apologizes for everything she did to Lilo and tells her she isn't weird and that she wants her to be her friend now. Some time afterward, the kids, aliens, grown-ups and MacCrab play on the beach. Emily appears, so MacCrab transform her into an actual horse, who Elena rides around with joy.

Some time after the vacation Lilo, Stitch, Mertle and her friends are back in Kauai and are hanging out together and Elena is riding Emily around for joy and Moses is proud of Lilo and Mertle for getting along with each other.
