Gray Wolf is a well-known forest bachelor, a fine figure of a fellow or, as Willy's mom usually describes such guys, a real macho.
He looks a little wild but deep inside he is a good gay.
Once an unlovely thing happened to him: he put Yagha the Sorceress out of temper and, as a result, he lost his tail.
And, so that you know, a wolf without a tail is not quite a wolf, but an uncontrollable werewolf.
When the full moon is near, he consistently turns now into a human, and then into a beast. That is why he is longing to get his tail back.
