As the old mummy makes his way across a graveyard and through a haunted castle, he swallows all kinds of creepy things. From a rat to witches' brew, and a crow to a spooky ghost, this mummy keeps swallowing and swallowing...until finally there's a knock on the door. Trick or treat! Jennifer Ward's fun text and Steve Gray's zany artwork add a spooky Halloween twist to this adaptation of the popular song.
