It is still playable, if you die as an arctic hare, you will have the option to respawn as a chipmunk. You can also die as a mouse or shrimp in the arctic.
The Chipmunk is a light, caramel brown, with three dark strips running vertically down its back. The small half-moon ears just behind the large eyes are a slightly lighter shade than the rest of the body.
The Chipmunk has a small muzzle, hardly noticeable and tipped with a small black nose.
