Yes. I do indeed have a mini for the Trapdoor Alligator :)
Sadly, the 'trapdoor alligator concept is not mine. It was created by R.K. Milholland over at Something Positive for his comic strip. I just like using them in the game... it puts a surreal twist on things. It's a bit of whimsy that I use at the table, but I'd never go to print with it unless I had permission. Which at present, I do not.
