Goggley-Blade

Goggley-Blades are fish and occasional foes of Wario in the Game Boy Advance game Wario Land 4. They have saw blades banded on their heads (probably serving as a hurtable backfin) and wear goggles, hence their name. These attack Wario by swimming toward his position with an enormous speed, although only at a glance to Wario. However, they don't follow Wario. So, if Wario evades them, and they start to attack, Wario can just swim away when attacking, and the Goggley-Blades would swim forward. They must be defeated from below.

Strangely, they have two tailfins what resemble aquatic birdfeet. But their two handfins are just normal fins for fish. Also, they resemble piranhas.
