Leader of the weasel trio featured in the graphic novel sequel The Resurrection of Doom: https://disney.fandom.com/wiki/Roger_Rabbit:_The_Resurrection_of_Doom

The "Weasel Trio", as we like to call them, are probably the most interesting Disney weasels out there besides the Toon Patrol. While they're certainly derivative of the original five, you can tell a lot of thought was put into giving them interesting designs. I'm glad to finally give them their due after all these years. (Note that "Slithy" is fan name that I and fellow weasel fans came up with. He probably doesn't have an official name at all.)
This also happens to be the drawing that seemed to impress that Disney animator I met the most.

One problem I have is that while it's fairly easy finish a drawing, it's annoyingly difficult to clean up the smudges and eraser marks after scanning it. I drew this around when I was still on the Toon Patrol board.
