Jorax runs the Discount Space Prize Emporium on the Space Station, and rewards those who helped defeat Dr. Sloth. Strangely, Jorax has a missile in the background of his shop, but doesn't offer it for sale. Jorax's name is also given as Joroax, though this is assumed to be a spelling mistake.
Hey, you must be lookin' for the prize shop, for people who helped fight off ol' Doc Sloth. Well, you're in the right place, buddy.
