Sandworm in Beetlejuice - The Animated Series
Like the movie, Sandworms are the only things Beetlejuice fears. But unlike the movie, Sandworms do not live on Saturn. Instead, Sandworms live in the Neitherworld in a desert region called Sandwormland, which seems to exist below the Neitherworld. It is sort of a "Forbidden Zone". Sometimes, sandworms leave their habitat and go into more urban areas. Lydia convinced Beetlejuice to save a baby sandworm.
