After getting abducted by Team Rocket, Pikachu and Piplup end up stranded on a deserted island, where they meet a wild Corphish that is guarding a mysterious glowing jewel. While their trainers search for them, Pikachu and Piplup assist Corphish and a school of Mantyke in preparing for a major event involving the jewel, which they learn is to regenerate the legendary Pokémon Deoxys.
Tropes
- Because You Were Nice to Me: Deoxys shows gratitude to Pikachu and Piplup for helping it to regenerate.
- Breather Episode: This episode serves as this coming from the intensity that is the two part Iron Island episodes.
- Continuity Nod: When Dawn asks what the legendary Pokémon is that, Ash easily identifies it as Deoxys, which he saw during the seventh movie and during Battle Frontier.
- Deserted Island: Pikachu and Piplup end up stranded on one, which sets the plot of the episode in motion.
- Didn't Think This Through: Narrowly averted. While helping collect magnetic rocks, Pikachu prepared to blast a big one, only to be stopped by Piplup who reminded him they were underwater and he'd fry all the Water-types. Pikachu naturally feels sheepish for forgetting that.
- How We Got Here: The Cold Opening shows Pikachu and Piplup lost on the deserted island calling out to their trainers. Immediately afterwards, the episodes flashes back to Ash and the gang riding on a boat.
- Mugging the Monster: Upon seeing Dexoys, Team Rocket immediately decide to capture it. Of course, since Dexoys is a legendary Pokémon, it effortlessly sends them blasting off.
