The other two weasels from the Roger Rabbit graphic novel Resurrection of Doom: https://disney.fandom.com/wiki/Roger_Rabbit:_The_Resurrection_of_Doom
Again, the names Doofus and Al are fan nicknames and not official.

Not nearly as interesting as Slithy, but Al does seem to take inspiration from the unused weasel Flasher.
Doofus only has that jacket in (most of?) one page, but I figured it'd be better if he had it. Their colors are also pretty inconsistent, so I tried picking the most interesting variations.

This was drawn around the same time as my 2nd Slithy drawing (whenever that was).
