"Show me the skeleton of any animal and I will show you how it must move," said Albert Hurter. Unfortunately, there are very few, if any, Grinch skeletons about, so we had to do with Dr. Seuss' careful academic drawings of the living Grinch.
"All fully animated characters have implied, but very real, skeletal structures and the muscles to move themselves about. Once decided, the implied skeleton of Bugs Bunny, Daffy Duck, Pepé le Pew, or the Grinch must be respected, or it will become inconsistently rubbery and lose all claim to believability.
"The Grinch fell well into this classic anatomical crew. His skull and enormous set of teeth are not notably different from Elmer Fudd's, only more so. His body is a sort of huge, sagging, pear-shaped, Porky Pig-like structure. His arms, legs, skinny elbows and bony knees are not unlike those of the Coyote. So, we had a full-length portrait."–Chuck Jones, Chuck Reducks, Drawing on the Fun Side of Life
