Friend and former art studio-mate, Jason Dryg, made this great Slimer. Here's what he had to say about it on his blog:

Josh Ellingson has drawn 100 and some odd Slimers on a dry-erase board, and shows zero evidence that he will slow down. I asked if I could do one and he said I should. But what could I do he hadn't done? I had to add a second character.
