The tree branch and acorn tell the story. The squirrel beaver thing broke his leg and needs to get the acorn. So he makes a flying contraption to get him up there. I thought mixing him up a little would be more interesting.
It's a great concept, but it would be better if it was just a "flying squirrel" but with fake wings. I.e. lose the branch and cast, and make him look a little more like he's realistically flying, and I'd 5$$ it for sure!
Basically, he's a combination of beaver, squirrel, and human. Enjoy!
