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 hits their fangs, he'll hurt. They can be defeated when Wario runs fast via a Max Fastosity Dasherator.

Trivia

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