Mash is an enemy that appears in Bomberman 64. It is a rock-like creature. It moves slowly and aimlessly, stunning Bomberman on collision. When it is defeated, it will split into two smaller Mashes, which are identical in terms of behavior and hit points. While Mash takes six bomb blasts to defeat, a single Pumped Bomb thrown on top of it will defeat it.
In Hard Mode, Mash and its smaller versions move more quickly and take seven bomb blasts to destroy.
