The O'Brien family are new in town. An ordinary family - well, almost. Roy O' Brien is a little different - he's a cartoon! Ghoul Claw is supposed to be the scariest movie in years. Roy is eager to see it but his mother forbids it, as he is much too young. Roy and his friends manage to hatch a plan to fool the cinema attendant and gain entry to the film. It turns out to be a bad idea - Roy is completely terrified by the movie and it proves very difficult to hide this fear when his nightmares appear in a thought bubble above his head.
