Item: Shirt of the Tarrasque, granting the wearer the Tarrasque’s Extraordinary Ability Carapace: The tarrasque’s armorlike carapace is exceptionally tough and highly reflective, deflecting all rays, lines, cones, and even magic missile
spells. There is a 30% chance of reflecting any such effect back at the
caster; otherwise, it is merely negated. Check for reflection before
rolling to overcome the creature’s spell resistance.

BICYCLE MONSTER!

LIKE A BIKE BUT BETTER!

LIKE A DOG BUT WORSE.

HIS NOSE SHOULD MAYBE BE WETTER.

IF YOU PET HIM, WHOOPS, YOU’RE CURSED!

I constructed him from  wool, wire, a red velvet dress that fit me badly, and a bicycle I got out of the trash.

Item: Bicycle Monster

Encounter: flouncy insectoid-person of some sort that either has no explanation for itself or refuses to give it, preferring to flit hither and yon in the cold night air; it requests to join your party and assist as it is able. Upon consulting the proper lore, the party discovers that actually it is one of the early larval forms of a Remorhaz. If allowed to gain a sufficient number of XP, it will begin to manifest extra limbs, ravenous hunger, and/or jagged chitonous spines that radiate heat.

Encounter: 2d8 Flumphs

I had always looked at these and assumed they were low-level monsters, but now I’m noticing “Intelligence: Average”, which I believe by 1981 manuals was the same as humans and dwarves and such. I don’t know what languages they’re up on, but they could probably hold conversations, or even hold down jobs. (If so, why do they have Treasure Type: Nil? Do they blow it all on drow rogues playing blackjack on the streets of the Underdark? Do they send it to televangelists for some sketchy deity? #worldbuilding)
