Unithorn

Unithorns are purple-colored, unicorn-like enemies in Wario World. They do not appear to have bodies; only their floating heads are ever seen. They can only be found when Wario falls off a level (down a pit) and lands in the Unithorn's Lair. They will try to bite Wario and steal his coins. To escape, Wario has to break various boxes to find one with an Escape Spring inside. All other boxes have Smiley Bombs.

Unithorns are light purple in color, are rhino-like in appearance, and have huge thorns at the tips of their noses for horns.
