This is my third incarnation of this character/creature. I thought about going for articulation but decided to just sculpt a solid piece (maybe next time. :hmm He is sculpted out of "green stuff" putty. An interesting rumor I encountered while researching this character is that Attark IS in Return of the Jedi, or at least his snout is. It is the "tentacle arm" that grabs C-3PO in Jabba's dungeon. While I have not been able to verify this it does seem really plausible and would explain why no one on the throne room set remembers seeing this creature.
