Well, I've been biting my tongue, waiting for other people to play:

Here's my list:

Mojo: madd maxx, because he's got a magical quality or Beverly because she's so calming and supportive;

We Can Do It: Red Rider because she's a racer chick or Pam because she crashes a lot and still gets back up.

Grover: This would be me because I'm so goofy.

Tux: DnvrFox, because he's kind of the host here since he started the forum.

UK: Stapfam, because he's from the UK

SD: DG, as previously stated

W: Wisconsin Badger for Tom Bombadil
