From the Super Mario Wiki

A Scare-oh! is a golden lion-like statue in Wario: Master of Disguise. Only six are seen in the whole game, two appear in the outside of the Smithsnorian Museum, two in Poobah the Pharaoh's Pyramid, and two in the Allergia Gardens. They try to hurt Wario; it is hard for Wario to jump on their heads since they usually grow spikes on their heads to prevent Wario from hurting them. Also, they shoot purple coin-like objects, which hurt Wario on contact.

In-game description[edit]
