Well.. Okay... it looks like you all are using the bad unwrapping that comes with the model.. The texture i stretched badly on the legs.

Well.. i can give it a try... do you want photo textures or painted? (painted relatively good then)

Squirrels climbs in the same way as they run.. :P (it could make it whole pretty interesting to do a game that way ^^... every wall are ground to you… )
