In many areas, it is possible for a "natural object" (e.g. a Berry tree, tall grass, a large rock, an iceberg, snow or sand piles, etc.) to appear behind an opponent in a wild or Trainer battle. These objects can be hit by certain moves that can target multiple Pokémon like Surf or Earthquake. If the object is hit, it will break or drop Berries and remain in that state until the end of the battle, when the player will pick up an item ranging from Berries to stones and other items.
