Monsters with Stunning Fist

[the Jester]

So if you have two claws and a bite, and you're, say, an advanced babau demon fighter/assassin, and you take Improved Unarmed Strike, Improved Grapple and Stunning Fist, can you combine them? In other words can you attempt to stun with a claw attack?

 

[Viktyr Gehrig]

I think the requirement of Improved Unarmed Strikes very strongly implies that it is something that requires a "normal" unarmed attack, and not a natural weapon.

I would not be inclined to allow it.
