Encounter: the Busey Thumbrantula; feeds on raw meat. If a character or other creature is bitten, its venom causes them for the next d4 hours rounds to be irritable and aggressive and uncontrollably bare their teeth at all times.
Encounter: a horrific mass of writhing, interconnected snakes; a slitherin’ slippery sleazeball and a highly-skilled bounty hunter in its home-realm beyond the ken of mortals
Encounter: horrific living hollow cone that generates oversized fries, each of which is as nourishing as a meal for any creature, including itself. Regardless of the language it speaks, it somehow always has that culture’s equivalent accent to a disreputable 1950s street vendor.
Encounter: a top-hat with legs and a pair of hovering double-ended hands; the hat contains an oversized Deck of Illusions, which the free hand can use as a standard creature with a standard deck; the other hand has a scepter that can trap creatures in one of ten pocket-dimension cells within the hat. As with the Mirror of Life Trapping, if it accidentally tries to trap an eleventh creature, a random one of the other ten is freed, and if the hat is destroyed then they all are set free.
Encounter: an inbred Beholder; it has no mouth and the blind eyes on its scrawny, underdeveloped eyestalks can only cast Entangle, although instead of vines it’s more eyestalks.
Encounter: Leonard; not evil but does not understand the plane, and feeds by grappling creatures with the green tentacles and licking them to harvest their Charisma points
Encounter: Clockwise Blazer; once per round can blast Obscuring Mist or either version of Pyrotechnics. Said to possess certain arcane knowledge, if you can get its smokes away from it long enough to free its mouth up.
Encounter: actual name is unwritable with human language, but has wound up nicknamed the Octophant; while most Aberrations are all about harvesting pain and dealing psychic damage, this fellow would rather have a friendly grappling match. Beat it and it will grant you a Wish! Lose and you are under a Geas to grant its wish, though. It has unusual wishes.
