Swordfish (Wario)
From the Super Mario Wiki
The Swordfish are fish enemies found in the game Wario World, in the Horror Manor level. When Swordfishes are in the water, the player can see where they are, other than that, they will be invisible to the player. However, without warning, a Swordfish may jump out of the water and try to bite Wario. While they are out of the water, Wario has a chance to attack the Swordfish. Once it is dazed, Wario can pick it up and use a Power Throw, Piledriver or Wild Swing-Ding on it to defeat it.
