Four brand new stories in which Horrid Henry makes his own scary movie The Undead Demon Monster Who Would Not Die persuades Peter to hand over his stash of Grump Cards (as a brilliant scheme to get him out of the punishments his parents give him) and spends a weekend at Aunt Rubys where he has to share a bedroom with his two arch-enemies Stuck-Up Steve and Bossy Bill. Then when Henrys school decides to have a mini-Olympics he sets up his own Holympics with medals for crisp-eating TV watching and Burping to the Beat.
