The Rowdy Mouse, known as Delinquent Mouse in Japan, is an enemy that appears in EarthBound. These small grey mice first appear in the caverns of the Giant Step, the first "Your Sanctuary" location, and are often found alongside Black Antoids and Attack Slugs.

Rowdy Mice later appear in Brick Road Maze and the cave of the Rainy Circle, the fourth "Your Sanctuary" location; in the latter, they may be paired with Attack Slugs and Struttin' Evil Mushrooms.

The Deadly Mice of the Fourside Sewers are their stronger counterparts.


Rowdy Mice frequently use biting attacks; the real danger lies in their absurdly high Guts stat, which means unless defeated quickly, the party may be SMAAAASHed into submission.

This is an especially dangerous situation to face early in the game, where the most that can be done is to repeatedly attack it, while using whatever items are available to heal any serious damage. Rowdy Mice may drop bread rolls upon defeat.
