Slade speculation. Formerly a discussion on Natural attacks.

[Mystic Muse]

I'm asking this for two reasons.

1. I'm playing in a game where I have a tail attack I didn't think I was going to use since a greatsword does more damage
2. I was curious whether a Monk who got polymorphed into say, a twelve headed hydra would get both his natural attacks and his unarmed strikes.

I read that they did stack in a thread about natural attacks that was on here a day or two ago and decided I should ask.
