Scarracuda

Scarracudas are fish-like enemies with silver fangs in Wario Land: Shake It! They can jump out of the water if Wario comes too close. If Wario gets hit by their fangs, he'll get hurt. They can only be defeated when Wario runs fast via a Max Fastosity Dasherator.

Trivia

 * Their name is a pun on Barracuda and Scar, although they appear as Piranhas.
