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.

It should be noted that Unithorns have a fear of Smiley Bombs as they will not attack Wario when one is uncovered inside a box. However, once the bomb explodes, the Unithorns will continue to harass Wario. Wario can use the Smiley Bomb to his advantage as he can pick it up and walk around with it, making the Unithorns run away from him.

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