Now it's happened to Sebastian's little brother, Rory. One minute he's a normal little kid hanging out in his backyard. The next, he finds himself walking through stuff: the back porch, walls, even people! What's a monster-kid gonna do?

Rory decides that he'll try and find some other sprits and ask them how to get "un-ghosted." So he heads up to the local haunted house to give it a try. What Rory doesn't know is that if he doesn't get the answer soon, he'll only have a ghost of a chance of ever being a kid again
