Inktober Monstrosities: Z for Zorbo

At long last we reach the letter Z, and in the search for forgotten and overlooked creatures we find the
zorbo - a strange koala-like creature that can absorb protective properties from its surroundings, as well as draining protective magical items.

The zorbo first appeared in the Monster Manual II for first edition AD&D, then later in the Monstrous Compendium Annual volume two...

... and that was it I thought, only to find out that it actually appeared in the Tomb of Annihilation adventure for fifth edition, which strictly speaking means it's disqualified for this list (the locathah appeared in Secrets of Saltmarsh AFTER it appeared here), so maybe it'll be replaced later... we'll have to see.
