Little Mouser

Shown with a Little Skull Mouser

Little Mouser's are small blue mice that wear bandana's just like Mouser. They don't throw bombs, but they will grab one of Yoshi's eggs if they get close enough. In some levels of Super Mario World 2: Yoshi's Island, several small holes can be seen on the walls. If a Little Mouser lives in one it will pop out and try to steal an egg.

Other versions are Little Skull Mouser's who wear an unknown species skull on their heads. They hop blindly around and will lose their skull if Yoshi steps on them.

If Yoshi's eggs are out of reach Little Mouser's will hop and squeak while trying to grab them.

In Paper Mario, a tribe of desert Little Mouser's live in Dry Dry Outpost. They are called Nomadimice and live with the Dryites. In Paper Mario: The Thousand Year Door, a white Little Mouser named Ms. Mowz joins Mario's team.
