A little hedgehog is fast asleep when all of a sudden, the light clicks on. He is not happy about being woken. “Turn off that light!” he demands. The light switches off. And then on again. And off. And on. “Who keeps doing that?!” The hedgehog bumbles around, exasperated, in a flurry of onomatopoeia — GRRR!! OW! CRUNCH. BANG! — as his room mysteriously goes from dark to light over and over and over again.
