All children grow up eventually but Peter Pan wanted to be old right away. He was sick of baby kid stuff so he ran off to a magically spooky place to become...a mummy! One night in the normal world Peter overhears Wendy Darling telling her brothers super scary stories. He decides they'd love it in Mummy Land too. But Peter's home is filled with many grim ghouls - including skeleton pirates who will put them all in grave danger.
