Buy an Ernie costume to join Bert and Sesame Street this Halloween. Ernie is a Muppet from the long-running PBS children’s show that forms a comic duo with his roommate Bert. Ernie is the shorter and stouter of the pair who has a fondness for baths with his Rubber Duckie as well as a distinctive laugh. Bert is the world-weary foil to Ernie’s naive troublemaker.
