Blue Fish (ギョッピー, Gyoppi, in Japan) is an enemy that appears in Bomberman 64. It appears in water, swimming around aimlessly. Once the water has been drained, Blue Fish will walk around aimlessly on two legs, and will chase after Bomberman if he is close. It stuns Bomberman on collision. Blue Fish takes one bomb blast to defeat, and a single Pumped Bomb thrown on top of him will defeat him as well. It is possible to destroy a Blue Fish while it is swimming, but any items it yields will be lost.
In Hard Mode, Blue Fish moves more quickly, but still only takes one bomb blast to destroy.
