Let me get this out of the way - Passel Argente looks to me like a hybrid of the Djinn from Wishmaster and Yogurt from Spaceballs.
Okay, I always assumed Passel was a new character in AOTC (if you don't recognize the name he's the green separatist on Geonosis). But last night while going through a pack of Young Jedi (TPM era) cards I found a card of Passel from TPM. I don't recall him in the film, do you?
I'll include reference shots here, first the card from TPM . . .
