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 Cannonball before Gantu does. Meanwhile, Lilo's hula halau participates in a sand-sculpting contest.
- Lilo called the hula teacher "Mr. Petuli" in this episode, though she did later refer to him by his actual first name, Moses.
- The net that Gantu uses for Cannonball appears to have no air holes.
- Moral: "Aloha" means to help others.
- Unlike most episodes of Lilo & Stitch: The Series, the characters in this episode are given shading. Most episodes have the characters drawn with flat colors.
- Stitch is seen wearing his superhero costume that consists of all stolen items: a pair of red sunglasses, a red towel, a green bikini top, and a letter S (from the PARADISE POOL sign).
- When Gantu notices Cannonball passing by, he says, "Just follow the bouncing abomination." This is a reference to the bouncing ball seen in sing-along videos in which viewers follow an animated ball that bounces across the top of the lyrics, landing on each syllable when it is to be sung.
- Pudge was mentioned by Lilo in this episode.
- Lilo revealed that she had a pet goldfish named Koko who died.
- During their battle to reclaim Cannonball, Stitch hits Gantu with Nani's X-Buggy, a callback to the first film.
- When Lilo and Stitch take Cannonball to the sand-sculpting competition, his stomach becomes Finder's size.
- This episode marks the first appearance of Charles and Mary. They only made a brief cameo when Gantu trampled past them to recapture Cannonball.
- In "Felix", Cannonball was seen ruining the beach with his tsunami-sized waves, implying that he was incompletely rehabilitated.
