Welcome to Spook School - where lessons include learning how to fly, walking through walls and making objects move! Charlie's not all pleased to find himself at Spook School - he spent quite enough time at school when he was alive! But soon he proves himself to be a pretty impressive spook and is invited to join the Spook Squad, who are sent down to earth to investigate strange and spooky goings on. First on the list is the deadly Mothman, rumoured to be the size of a horse, with really sharp claws and a very bad temper.
