The ugly, ugly Neo-Otyugh, a D&D monster #toy from LJN toys. Bit of a bendy, actually, with wire embedded in the plastic for some posability (until the wire breaks).
I’m … fond of it. I suppose. It does look like it gives nice hugs.
This is the really deadly (and really ugly) #Grell, another LJN-made D&D monster bendable #toy which likely got little to no respect in the early 1980s.
There’s a lot going for it. Brains, tentacles, and … a beak. The Fiend Folio creature has these features, but the accompanying illustration is better than the effect here, which is sort of brains-on-a-cracker with green extremities.
Third of that short-lived, incomplete series once attempted (back in 3 November 2011, a late entry) of Monster Manual monsters in #watercolor: monsters of the alphabet. It's the carrion crawler, present in nigh every edition and iteration of the game.
Like the previous entry, this was also based on a #toy, this time something officially licensed: LJN Toys' bendable rubber critter.
