Are there any puppet patterns available for an obese puppet? I'm looking to make a muppet-style puppet with a nub of a chin, and a "tire" of a second chin.

Also, is there a pattern available that resembles this muppet: Hardhead Henry? I'm not looking to recreate this character, but this muppet has the round head and "frown" that I'm looking for. If not a pattern, is there a generic kit for this type of puppet for sale?
