Hey, everyone!
I'm new to pathfinder (an old veteran of 3.0 and 3.5), and I've been enjoying playing around with novel possibilities. I took some time rolling up a character and relearning the rules, and I just wanted to check to make sure I haven't done something wrong in my understanding of how this all works (particularly natural attacks). We're starting at fourth level, but I'm providing the build I intend to take up to level 6 to make sure it's legit. The attack values I've provided are when using natural attack shifting, and I'm only providing feats that are integral to combat operations.

I'm mostly concerned about how to go about incorporating the at will shift attacks into the attack action. I currently am working under the understanding that a single shifted body part can attack twice (The only available natural attack for Frogs to gain, for example, is Bite, and it seems insane that Frog based shifters would be limited to a single natural attack), so I feel semi-safe with the double Croc tail slap. My main concern is whether I have to limit myself to either crocodile tail slap or lizardfolk tail slap. Ideally, I'd like the extra croc tail to shoot out just above the lizardfolk one.
Alternatively, is it possible to make the double shift go to foot claws or something instead? I'm mostly just running into the issue of doubling up on body parts here.
