The kids continue walking until they exhaust himself, to the concern of their Digimon. Taichi is especially guilt-ridden after the events of the previous episode, though Mimi encourages him to keep going. Palmon fantasizes about becoming a giant Togemon who can give everyone shade, until Mimi points out that, what do you know, there ''is'' a giant cactus next to them! The kids run to the cactus...only to find out that [[GlamourFailure there seems to be no shadow from the cactus]], and are even more confused when the cactus disappears, having been a mirage.
Another light appears and [[MrExposition Gennai]] returns, and the kids yell at him, asking why their Digimon haven’t evolved. Gennai explains that the Crests and Tags will only evolve their Digimon the right way if the kids raise their Digimon properly, but unhelpfully disappears before he can explain how. Now more confused than ever, the kids wonder if they’re really capable of raising their Digimon “correctly”.
As if their situation weren’t already confusing, a giant luxury liner cruise ship starts coming at them in the middle of the desert. The ship turns out to be driven by a Numemon and, seeing the exhausted Koromon, Taichi asks if they can rest on the ship. Mimi eventually gets the Numemon to allow them on by flirting with him, and the ship turns out to be quite luxurious.
[[GenreBlind Having learned absolutely nothing from their previous encounter with suspiciously luxurious amenities]], the kids bathe and gorge themselves on food. (Hunger seems to dull their ability to detect evil.) While Taichi and Jou discuss the definition of raising Digimon “properly” at the pool, they’re watched over by a Cockatrimon[[note]]Kokatorimon[[/note]], who recognizes them as the Chosen Children and tries to report to Etemon, who’s busy giving a [[DreadfulMusician horrifically bad]] performance to his Gazimon. Unable to contact Etemon, Cockatrimon decides to kill the Chosen himself, and orders his [[PunchClockVillain part-time Numemon workers]] to capture them for a raise.
The Numemon catch Jou and Taichi in a net, and Gomamon narrowly avoids this fate by somehow summoning fishes out of the pool. The Numemon approach Koromon, but Taichi evolves Koromon to Agumon, who staves them off until Cockatrimon himself shows up. Without further ado, Cockatrimon [[TakenForGranite turns Agumon and Gomamon to stone]], and takes Taichi and Jou’s Crests. Gabumon, Tentomon and Tokomon, fending off Numemon themselves, also fall victim to Cockatrimon’s petrifying attack.
Cockatrimon then tries to find Sora and Mimi, but upon entering the showers, finds that they’ve escaped out a window. He catches up with them, barely clothed and accompanied by Piyomon and Palmon. Cockatrimon reveals that he’s captured the other Chosen and tied them to “fry in the sun”, and intends to eat them along with the petrified Digimon. Piyomon and Palmon barely avoid Cockatrimon’s petrifying attack, and the four make a run for it.
Piyomon evolves to Birdramon and Palmon to Togemon, and they make short order of Cockatrimon by stuffing him into the ship furnace. The defeat of Cockatrimon [[NoOntologicalInertia restores the petrified Digimon]], and Sora and Mimi reclaim Taichi and Jou’s Crests.
Seeing the Numemon flee the ship, the kids and their Digimon reason that it must be dangerous to stay on the ship and flee. Cockatrimon himself [[NotQuiteDead pulls himself out of the furnace]] and declares revenge on the Chosen. Soon after, the wandering children find themselves being chased by Cockatrimon’s ship again.
The kids see another cactus and, seeing that it has a shadow, realize that it’s a real cactus. They hide behind it for shelter as Cockatrimon’s ship crashes straight into it and Cockatrimon is flung straight back. The ship explodes in the air, finishing off Cockatrimon for good.
A flower sprouts from the cactus, releasing Mimi’s Crest, which inserts itself into her Tag. Mimi wonders if she can bring up Palmon “properly”.
