Penguin (ペンペン, Pen Pen, in Japan) is an enemy that appears in Bomberman 64. It walks around very slowly and aimlessly. When Bomberman approaches, it will speed up slide on its belly, pursuing him playfully. It does not stun Bomberman on collision; instead, it only knocks him back for a moment.
Penguin takes one bomb blast to defeat, and a single Pumped Bomb thrown on top of it will defeat it as well. In Hard Mode, it moves quickly, but still only takes one bomb blast to defeat.
