Elmo loves his fuzzy, well-worn blue blanket more than anything in the whole world. However, when Elmo's blanket gets sucked through a colorful, swirling tunnel into Grouchland, the yuckiest place on earth, Elmo goes on an adventure to Grouchland to retrieve his prized possession.
The Adventures of Elmo in Grouchland is a 1999 American musical adventure comedy film directed by Gary Halvorson from a screenplay written by Mitchell Kriegman and Joey Mazzarino, based on a story conceived by Kriegman. This was the second of the two theatrical feature films to be based on the children's television series Sesame Street, after Sesame Street Presents: Follow That Bird in 1985. It stars Mandy Patinkin and Vanessa Williams alongside Muppet performers Kevin Clash, Caroll Spinney, Steve Whitmire, and Frank Oz. It features songs written by a wide range of songwriters, including Siedah Garrett, Jeff Elmassian, Andy Rehfeldt, Martin Erskine, Seth Friedman, and Michael & Patty Silversher, with a score composed and conducted by John Debney.
