Bogeyman

Children are scared of the Bogeyman. It’s not clear what he looks like but he is scary. He will get you if you suck your thumb or do anything naughty. He is tall, nasty and hairy and a bit like an ape. He hides under beds and in wardrobes and gets little children when they are asleep. Sometimes he scratches on windows in a scary way. There may be horrible pirates called bogeymen. There can even be a Bogeywoman.
