Horrid Henry is about to be out-naughtyed!

Hack and Whack - two angelic looking Viking toddler twins - are on the attack! As they go marauding around their village, upsetting the apple carts, little do they know there is a force far more powerful than they: their mum! The story ends on the terrible two being plunged into a cold bath!

Gloriously funny, slapstick, fast paced action from the queen of funny.
