Moosey Mouse is a young mouse who lives above the store in Mopatop's Shop with his father, his mother and his baby sister. Moosey likes to explore the shop. Since Mopatop, Puppyduck, and the customers hardly notice him, he can do almost whatever he wants. He is a recycled version of the mouse puppet that was originally made for The Muppet Christmas Carol and later used for Stanley the Mouse in The Animal Show. For Mopatop's Shop, large hand puppet versions were made for closeup scenes inside their house, whereas the small rod puppets appeared in the shop set.
