Mouse

A mouse is a small mammal belonging to the order of rodents, characteristically having a pointed snout, small rounded ears, and a long naked or almost hairless tail. The best known mouse species is the common house mouse (Mus musculus). It is also a popular pet. In some places, certain kinds of field mice are also common. They are known to invade homes for food and occasionally shelter.

Mainstream Smurfs Media
In mainstream Smurfs media, mice appear as both regular animals and sentient beings. Smurfette had owned a pet mouse named Squeaky, who lived for a short time until he helped save Papa Smurf's laboratory from being burned up in a fire. During the Smurfs' time-traveling adventures, they encountered a sentient group of mice in Japan.
