On Melemele Island, a wild Dewpider leaves its nest in search of its own pond to call home. Along the way, it gets caught up in confrontations with various Pokémon who don’t take kindly to intruders.
Dewpider wears a water bubble on its head that lets it breathe on land, so when it sees Lana wearing one of Popplio’s balloons on her head, it thinks she’s a Dewpider, too! The Pokémon School class observes and encourages Dewpider as it searches for a new home, battling opponents in the process. When it finally succeeds, it happily begins building its nest, inspired by its new friend Lana.
