Struttin' Evil Mushrooms (いけないキノコ ikenai kinoko) are enemies fought in EarthBound. They are relatives and palette swaps of the Ramblin' Evil Mushroom. They have a yellowish green tint with dull yellow spots. When they are being fought in Jeff's side, they look just like Ramblin' Evil Mushrooms.
The Japanese name ikenai ("can't go," or "naughty") contrasts with the aruku ("walking") of the Ramblin' Mushroom.
