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.

Elmo's back in Grouchland to sing some of his favorite songs with his new friend Grizzy. There's just one problem - Grouches aren't supposed to cooperate, so Grizzy won't sing along!
