The Adorable Chuspiki - Polymorph Attack

[SillyString]

I'm planning on polymorphing myself into a Chuspiki (Bestiary 5) by using greater polymorph, would I gain the ranged air blast attack?
If not, i'm assuming I would get 1-1/2 str to damage on the tail as its my only attack?

No and yes

Thanks, a player at my table was arguing otherwise, so i figured id check :)
