Lilo, Gantu, and their friends are all trapped on a forbidden island.
Both Lilo and Gantu are trying to capture Experiment 619, a fireball-shooting creature. They follow him to a forbidden island (taking with them Jumba, Pleakly, Stitch, and 625). 619 destroys their boat, and pins them in a cave. They must learn to work together to catch 619 before they run out of food and water.—Tony-B4
