From the Grim Reaper series by Christopher Moore (A Dirty Job, and Secondhand Souls). He's one of the Squirrel People which Moore based off of of the sculptural assemblage works done by Monique Motil.
This one likes cheese. And has a specific piece of anatomy that he uses to tie his wizard robe shut.
There's really no way to properly describe the character, but he's hilarious.
Many thanks to my wife for doing the inking on this one.
