When Molly wakes up in the middle of the night, she hears the sound of a step on the stairs. It could be a crocodile creeping up to catch her ...Or a giant giraffe outside on the landing ...Or an enormous elephant turning the doorknob and opening the door ...Or even a night monster come to gobble her up ...But when Molly surprises the tiptoeing beast, she gets an even bigger surprise of her own!
