'Oliver is a normal happy little boy, until one day he wakes up with Grumbles in his head… and Grumbles IN HIS BED! The Grumbles dance on Oliver’s chest, tug at his ears and cause all sorts of trouble for him, but when they run away with his snuggle blanket it’s the last straw! Will Oliver work out a way to tame those terrible Grumbles?'
