The Greedy Mouse is an enemy in Mother 3 that is encountered in Sunshine Forest. It is much weaker than its stronger counterpart, the Greedier Mouse. They move rather quickly on the overworld, making them hard to avoid. They mainly attack by biting. Occasionally, when their HP is low, they'll eat the cheese they hold, regaining HP. It may waste a turn by hiding its cheese. They are not a threat unless encountered in groups.
They are also one of the few animal enemies that does not “become tame” when beaten - instead, it “was taught a lesson”.
Its battle sound is Battle Sound 20 which falls under Code Numbers 496 for regular attack, 497 for Smaaaash! and 498 for Miss.
