The Glob is a large, sentient ball that appears in the Fraggle Rock episode "Boober and the Glob." The glob rolls itself into the Great Hall during Joke Day and begins devouring Doozers.

Although the Glob has no apparent skeleton, Boober succeeds in tickling its funny bone with a series of knock-knock jokes.

It is not known where the Glob came from, or whether there are other Globs in Fraggle Rock.
