Beaver-- big buck teeth, ready to get busy, maybe a construction worker.
Check out the Squirrel - he'd make a great beaver with a tail change. http://www.axtell.com/woods.html
Armadillo-- kind of an armor-plated possum.
We will make one someday!
Reindeer-- great at Christmas. can also be a regular deer.
On the list for "someday"....
Walrus-- more big teeth
Same list. I love walruses!
