Scarracuda

Scarracudas are piranha-like enemies with silver fangs in Wario Land: Shake It! Their name is a pun on the predatory fish, "Barracuda", and "scare", although they actually resemble Piranhas. There are two varieties of Scarracuda: red and green ones. Red ones just swim around in a pool of water. However, green ones can jump out of the water and attempt to bite Wario if he 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.
