Redhawk Caldera i was twelve years old and bullet proof

Peter was probably a very boring play-fight mate, because he rarely if ever attempted to fight back, preferring to giving up, giggling and trying to lick the other's chin or cheek. The worst thing you could expect from him would be him trying to grab his opponent's ear. And even then in a very gentle manner. 

Therefore, when Ferret attacked him, he fell backwards with a muffled thud, let out a little whimper, when he felt a tiny rock poking in his back, and with his belly facing upwards and paws drawn to his body he looked his crocodile of the brother and smiled happily at him. As if being attacked was the greatest thing in the whole world.
