The keen eye of Grognardia's James Maliszewski put my spell-checker to shame in noticing my caption in which the Paladin implores "Taste my holy steel, *fowl* arachnid!"
Even after fact, I decided to leave in that flub, as James' vision of a "chicken-spider" still makes me giggle, even just typing about it here.
At any rate, I didn't really have a good Otus pic to pair up with that shot, but I just liked it, so I bunched it the others there. Well it was kina eating at me...I mean, I knew there must be an old-school D&D illustration somewhere, by one of the greats of that time...but where, and by whom?
Tried googling. Failed. Broke out some of the old tomes. Ah-ha! There it was. And so here it is, paired with a reverse-image of my original pic...a wonderful little sketch by the incredible Bill Willingham of a Tarantella:

If that creature name doesn't ring any bells, it may just compell you to dance. Check out it's description in the Monsters section of my favorite D&D ruleset, Moldvay's Basic D&D box set, page B43 (please excuse the photo, it's all I could find, and I don't have a scanner or camera on hand at the moment...oh and I am far too lazy to type it all in here by hand):

So who's dancing? Yeah, me too...for 2d6 turns, as the dreaded Tarantella utters in Tarantellaic (or is that Tarantallaese?), "Bailamos, you *fowl* humanoids!"
