I don't know what you are but...

... I don't trust you.
Just a random thing I thought up after seeing the episode of Legend of Korra where she does that hand motion. Though I'm quite sure Pinkie Pie is just doing it to mimic her, and then she would probably just start talking non-stop at Korra like she does with everyone, and being all happy and what not. XD
Though really, they have probably never seen each other's species before with the avatar universe having cross animal, and I've just never seen a human in the MLP:FiM universe. So I could see them being suspicious.
So yeah, if you can't guess I completely gave up on Korra's hands after a while. Don't judge me. O.< -eye twitch- Besides the hand issue, I had a lot of fun doing this. Wooooot! Fandoms!!!!
Korra and Pinkie Pie belong to their respective owners!!!!
