The huff

And this, ladies and gentlemen, is why hedgehogs have no natural enemies, apart from humans and cars. When a hedgehog does not want to be moved it becomes an impenetrable ball of spikes and he can stay like this for hours on end, as it's a different set of muscles that controls the being a ball thing and inside the ball he's comfortably relaxed.

Essentially, this is Horatio throwing a 'I'm NOT going downstairs with you I found the BEST spot under this blanket, GO AWAY' tantrum. The spikes are not fully up, they go up on touch and he can also jump, as a ball, in the direction of any pressure. Really.

It took five minutes of talking to the ball and a piece of cat food to make him change his mind...
