Grewnge

Grewnge is one of the supporting antagonists in the animated film Treasure Planet. He is a large, fat tan reptillian alien with a pair of horns (one of which a gold ring hangs from) and a pair of antennae protruding from his head, and he sprouts a tail that is as thick as his fat legs. As one of the pirates in John Silver's crew, Grewnge seems to be the cannons expert, which is demonstrated when he fires with great accuracy at several incoming astroids during the meteor shower as well as the longboat Jim Hawkins, Captain Amelia, and Dr. Delbert Doppler were escaping in during the pirates' siege on the Legacy. He is also provoked easily to any insult regarding his weight, as he rears in to kill Doppler for doing so, but this distraction leads to his arrest alongside the remaining crew.

He is voiced by Jack Angel.
