In Pokémon Pokopia, Ditto learns Leafage from Bulbasaur and uses the move to restore greenery. This is one of the clearest examples of Pokémon moves becoming environmental tools rather than battle attacks.
Pokopia’s progression revolves around befriending Pokémon and borrowing their abilities. Leafage lets the transformed Ditto add or revive patches of vegetation, helping turn the opening wasteland into a more welcoming habitat.
Bulbasaur is associated with several grass-type moves in the wider Pokémon series, so Vine Whip and Razor Leaf are plausible but incorrect answers here. The move specifically demonstrated for environmental restoration is Leafage.
The game pairs this ability with Squirtle’s Water Gun, which hydrates dried plants. Together, those examples show how each friendship can unlock practical construction or gardening options while preserving recognizable Pokémon abilities.
