So, the others didn't float your boat, well, there's still plenty of mammals to go around!
The Unassuming Badger: All your life, you've been called a loner. Even your own father despises you, calls you the Devil. Your mother died in labour, and he's resented you for it... Especially since he couldn't possibly be the father; mom and dad are brown bears... you're a badger. You've never been taught to be socially graceful, so you've grown up... awkward, socially maladjusted. But now's your chance to change all that. You're a brilliant student and have just gotten yourself into a top Ivy League school. Now, as a freshman, it's your chance to leave a mark on the world... If only your new roommate didn't get in the way... He's a big hulkin' goat, and while rambunctious, you secretly wish you could be more like him... and him more into you.
Gettin' Down and Dirty as a Raccoon: You're never afraid to get your hands a little dirty. As a successful entrepreneur, business has never looked so good for you. Through your natural talents in thrift, knack for audacious moves and a just a bit of streetwise (oh, and also lots of support from your loaded parents), you've hit the big time, your company even going so far as to being traded on the stock markets soon! However... as great as this all sounds... you're far from perfect. You're definitely not afraid to get your hands dirty... Mom and Dad used to shame you relentlessly for it... but you're a compulsive dumpster diver, it's just encoded in your DNA. There's just nothing like diving into another's trash and scarfing down someone else's half eaten dinner, or a melted ice-cream bar. And while it's filthy and you feel terrible about it afterwards, you can't stop doing it. You know it's putting you at risk, what if the trustees find out? Damn, what if your girlfriend finds out? It's just another run to the dumpster, you're not sure which one, maybe it's the local heavy-iron gym, or maybe some kind of medical lab. All you know is, while your girlfriend's wondering where you are, you're getting a bite to eat!
Other: Rather write about some other furry critter? Go for it!
