No one believes in ghosts
Date 1988

"No One Believes in Ghosts" is a Muppet Babies song from the fifth season episode "Is There a Muppet in the House?"

In the song, Baby Piggy and Baby Fozzie are looking for Baby Kermit. Fozzie's scared of ghosts, but Piggy tells him that ghosts aren't real. She instructs him to call out "Oh, Piggy!" if he sees a ghost, and she'll come running to help... maybe. As Fozzie explores, ghosts appear and sing to him, convincing both Fozzie and Piggy that ghosts are real.
