This Real Monsters storybook about the best holiday of all - from a monster's point of view - describes how Ickis, Oblina, and Krumm venture out on Halloween night in order to frighten young children with their scariest noises. But kids on Halloween don't frighten easily - if anything the youngsters are impressed by the trio's cool costumes. It's only after the trick-or-treaters have gone to bed that the junior monsters are able to elicit some terrified screams - turning the disastrous evening into a success after all.
