The spirit chief of the mice is female. She once went to earth in the form of a grandmother to help a human hero who was in trouble. All his brothers had gone missing when they tried to track a bad spirit who had eloped with their sister. He found the village in which his sister was living and met an old woman (the spirit chief of the mice) who helped him by telling him everything that he must do to triumph over the evil spirit. Her help was invaluable in his success, so he offered her enough bear meat to last the age. She took this to her spirit abode under the earth. 
In those early days, the mouse was dangerous and combative. When the animals lived together in a single village at the center of the world, Mouse was always starting quarrels. Finally, a general civil war erupted among the animals, and all were scattered except Mouse. For what he did, Earthmaker condemned him to be small and in want. All his brother animals would now hunt him. This is why mice are secretive and fearful to this day. Because the animals had hunted one another, they were condemned to be hunted by humans. 
Mice can be go-betweens for the domestic and the wild, since they are a bit of both. Their devious nature is seen in a Trickster tale. Trickster persuaded Mouse to tell Little Fox to come out into the wild were there was a dead animal he could have all to himself. The fox, being condemned to eternal penury as he was, could not pass up such an opportunity, so Mouse led him to the animal, which Little Fox took to be a cervid. She helped Trickster tie the fox's tail to this animal, which turned out to be a horse. Having startled the sleeping horse, it jumped up and galloped all the way to the village, dragging Little Fox behind. Since then, out of shame, the fox has been more wild and reclusive than even the mouse. 
Even in their diminutive form, mice are often represented as dangerous. An evil spirit tells the children with Ocean Duck that unless they stay close to the fire, the mice will gnaw on them.  Hare forgot their bad reputation for this when he disguised himself by hiding one of his eyes under a bush. While he was off seducing Grandmother Earth, the mice nibbled on his eye, leaving it blemished.  The eye may represent the moon with its gray mare. The Dakota have a similar idea, holding that mice cause the decline of the moon by eating away at it when it is full.  Perhaps something like this is meant by the children's "Mouse Song":
|Who put on earth||can be like me?|
|No matter where they are,||I alone the little sky,|
|I myself touch.||'O'o! |
