Marumen

Marumen are purple or red spherical enemies of Wario Land 4. Along with Imomushi, they are among the weakest enemies in the game, as they do not 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. Most Marumen spawn colored purple, but there are some exceptions, such as the second screen in Palm Tree Paradise. The difference between the two colors is that defeating a purple Marumen yields two Small Coins, while defeating a red Marumen yields one Bronze Coin. Purple Marumen will turn red and vice-versa when Wario executes a Smash Attack near them.

Despite being weak enemies, more of them appear in Hotel Horror as the game mode difficulty increases: none are found in Normal mode, one is found in Hard mode, and four are found in S-Hard mode.

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