Marumen

Marumen (まるメン, meaning "circle face"), known in English as Bouncers, are purple, spherical enemies of Wario Land 4. They have a nose, and two feet. They won't hurt Wario in any way. Most Marumen are found in the early levels Hall of Hieroglyphs and Palm Tree Paradise, but many of them get replaced by Spear-Masks in the Hard and Super Hard modes. Otherwise, they are generally rare in all difficulty modes. They are mostly purple, but can turn into red as well, when Wario executes a Ground Pound near them.

Marumen are practically based on Wanderin' Gooms, as they won't hurt Wario as well. Red Bandineros share the same behavior.
