A tsunami-creating experiment appears with the threat of endangering the entire world if it reaches the ocean. Lilo and Stitch must use the newly designed X-Buggy to capture it before Gantu does. Meanwhile, Lilo's Hula halau participates in a sand-sculpting contest.
Notes: This episode has a slightly different animation style than most of the Lilo & Stitch series. Characters have soft shadows on them at all times, where in the other episodes and movies, shading is only used when the character is in sharp contrasting light. Canonball ( 520 ) is in the 5-series of Jumba's experiments, but even though they are classified as elemental manipulatord, he technically doesn't controll water, only forces it.
