The Humongous Chicken is a giant, slow-witted chicken (referred to by Huxley as "Tiny") who pesters Elmo as he tries to get to Huxley's castle to retrieve his blanket in The Adventures of Elmo in Grouchland. He mistakes Elmo for a worm. However, upon hearing Elmo sing "I'm a Little Teapot" to prove that he isn't a worm, the Humongous Chicken then thinks that Elmo is a teapot and declares that he can't have tea. He hasn't had his "din-din" yet and then he tossed Elmo off the tree branch.
The chicken is a normal-sized hand puppet, but is superimposed over the landscape to appear bigger. He is one of Dave Goelz's few Sesame characters.
