The Cloud Worm is a supporting character who appeared in Stuart Little TV series during the 19th episode "The Cloud Worm". He is a gigantic flying worm-like creature who claims to be the only one of his kind, and therefore has no need for his own name. It is his job to eat the clouds in the sky so the sun can filter through, making his presence essential to life on Earth. However, he has a tendency to devour any cloud he sees, including those that hold up Care-a-Lot.
