Bomb rocks are explosive rocks in the Pikmin games. In the first game, they can be carried by Yellow Pikmin, where their main purpose is to destroy rock walls. They can also be used to defeat enemies, and are particularly useful for doing so with bosses. When an enemy eats a Pikmin holding a bomb-rock, it explodes inside the enemy, harming it. They are usually found inside tin cans, pipes, or large animal skulls.
