Unithorn

Unithorns are purple unicorn-like enemies in Wario World, however they do not have a body, only their floating head is seen. They are only seen when Wario falls off a level (down a pit) into the Unithorn's Lair. They will try to capture 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.
