|The user turns the ground to grass for five turns. This restores the HP of Pokémon on the ground a little every turn and powers up Grass type-moves.|
Grassy Terrain creates terrain that envelops the field and replaces the background environment and any other terrain that is already in effect. The terrain fades after five turns.
This terrain has the following effects on Pokémon that are on the ground and not in the semi-invulnerable turn of a move.
- At the end of each turn, the terrain restores the HP of each affected Pokémon by 1/16 of its maximum HP.
- It boosts the power of Grass-type moves used by affected Pokémon by 50% (regardless of whether the target of the move is affected by Grassy Terrain).
If Grassy Terrain is in effect, unless the target is in the semi-invulnerable turn of a move such as Dig or Dive, the power of Bulldoze, Earthquake, and Magnitude is halved (even if the user or the target is not grounded).
If Grassy Terrain is in effect, Nature Power becomes Energy Ball, Secret Power uses the animation of Vine Whipand may cause sleep, and Camouflage causes the user to become Grass-type. Natural objects disappear and cannot be destroyed while Grassy Terrain is in effect.
Grassy Terrain also activates the Ability Grass Pelt.
