Monkey Bedtime

When a little boy lets a monkey in through his window, he doesn't expect it to bring all its friends. But when he is followed by six red-handed howlers, six macaques, ten capuchins and two great big baboons there's going to be trouble. Surely mum will notice the banana skins, the toothpaste, the handprints on the walls. Will he ever get to bed with all this monkeying around?
