Leafage is the Pokémon move specifically cited as helping players add greenery in Pokémon Pokopia.
Pokopia turns familiar Pokémon moves into practical tools for developing the environment. In the game’s official description, players can learn moves from Pokémon and use them to customize their surroundings. Bulbasaur’s Leafage is presented as an example of a move that can add a touch of green to the player’s world.
This use is different from the move’s usual role in Pokémon battles. Leafage is a Grass-type attack associated with Bulbasaur and other Pokémon, but Pokopia adapts it into an environmental ability. That design reinforces the game’s focus on cultivation and restoration rather than combat.
Leafage can be confused with Razor Leaf because both are Grass-type moves and both are associated with leaves. They are separate moves, however. The example tied to adding greenery in Pokopia is Leafage, making it the precise answer to this question.
