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 don't harm 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 S-Hard modes. Otherwise, they are generally rare in all difficulty modes. They are purple when first encountered, but can turn red and back again when Wario executes a Ground Pound near them.

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