Many plot elements and character names are based on "Treasure Island" by Robert Louis Stevenson. Eg. Billy Bones becomes Beelibones.
Beelibones is supposedly from the jewel-rich planet of Betelgeuse. In reality Betelgeuse is a distinctively red star which is visible to the naked eye in the night sky of the northern hemisphere.
Captain Tucker's hairy horned crew mate was also seen as the creature in the episode The Toymaker. He was the one who grabbed and took Dr. Smith away when the toymaker ordered him to do so.
