In Pokémon Pokopia, the player can learn Leafage from Bulbasaur.
Leafage is presented as a practical ability rather than merely a battle technique. When used by the Ditto protagonist, it helps add greenery to the environment and supports the process of restoring the world around the player.
Bulbasaur is an appropriate Pokémon for this ability because it is a Grass- and Poison-type Pokémon with a plant bulb growing on its back. Its association with vegetation fits Pokopia’s gardening and habitat-building systems.
Leafage can be confused with other Grass-type moves associated with Bulbasaur, including Vine Whip and Razor Leaf. However, the move specifically highlighted for environmental use in Pokopia is Leafage.
