Welcome to My Castle is a 1978 Sesame Street storybook released by Fisher-Price as part of the "Talk-to-Me Books" series. Each page features small vinyl circles which, when played with a "Fisher-Price Talk to Me Book player," plays audio, allowing readers to hear as well as read the story. The Count invites Ernie, Big Bird, Bert, Grover, Herry Monster, Cookie Monster and Prairie Dawn over for a tour of his castle.
