Rog was traumatised by a recent home invasion. But it wasn't a man wearing a balaclava he had to worry about. It was just a cheeky hedgehog, making noise and pooing around the house.
Maybe Rog just looked in the mirror with that new haircut of his.
...curl up into a ball when you're frightened, covering your testicles and you poo inside. You are a hedgehog!
