Bulbasaur helps the player in Pokémon Pokopia by using Leafage to add greenery.
Pokopia lets Ditto learn practical moves from Pokémon friends, turning familiar battle techniques into construction tools. Bulbasaur’s Leafage is shown as a way to restore vegetation and add green growth to the landscape.
This move-based building system is a defining idea of the game. Squirtle’s Water Gun can hydrate plants, while other Pokémon abilities assist with cutting, smashing, or shaping terrain. The player therefore chooses companions partly for the functions their moves provide.
Bulbasaur is a particularly fitting helper because its Pokédex identity is tied to plants and a seed carried on its back. In Pokopia, that botanical theme becomes useful for rebuilding the withered fields and attracting Pokémon that prefer lush habitats.
