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 three varieties of Scarracuda: red, green, and black. Red ones simply 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. Black ones live in the lava, but otherwise act the same as Green Scarracudas. If Wario gets hit by their fangs, he will get hurt. They can only be defeated when Wario runs fast via a Max Fastosity Dasherator, or Dash Attacking them while they are in the air.
