Elmo loves his fuzzy, blue blanket, and would never let anything happen to it. However, a tug-of-war with his friend Zoe sends his blanket to a faraway land, and Elmo in hot pursuit. Facing life without his cherished blanket, Elmo musters all of his determination and courage and heads off on an action-packed rescue mission that plunges him into Grouchland--a place full of grouchy creatures, stinky garbage and the villainous Huxley.
