Knock Knock Who's There?
Summary
A gorilla, a witch, a ghost, then a fierce scaly dragon hungry for his tea. Who will be next? Each time there's a knock at the door, there's a different monster, but each time they're wearing the same tartan slippers. Of course, it's just Dad, playing an hilarious bedtime game!
