Marumen

Circle Face (まるメン Marumen) is a purple, spherical enemy of Wario Land 4. They have a nose, and two feet. They won't hurt Wario in any way. Most Circle Faces 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.

Circle Faces are practically based on Wanderin' Gooms, as they won't hurt Wario as well. Red Bandineros share the same behavior. The name of Circle Face translates to "marumen" in Japenese.
