Aguanoggin (a.k.a. Crex) is one of the four duodenary antagonists in Treasure Planet.
Role in the film
He is an alien pirate in John Silver's crew who seems to be an pink anthropmorphic angler fish with a "T-Rex" complexion. He was involved in the raid on the Benbow Inn, being one of the first two pirates (the other being Verne) to storm inside before Silver entered himself. It is unknown what had happened to Aguanoggin in the film, as his last appearance was at a camp site where he, Silver, and several of the other pirates were sleeping.
