松鼠

A chipmunk, a small rodent with puffy cheeks. Depicted as a brown chipmunk in full profile facing left, sitting on its hind legs with a bushy tail and striped body. Generally holding an acorn or other nut in its hands.

May be used to represent a squirrel or related animals.

At one point, Google’s chipmunk was looking forward, squinting with a buck tooth. Microsoft’s previous black-and-white design could be mistaken for a skunk.
