You were a human who had arrived in Ponyville a few years ago.. and in that time, you had become pretty well acquainted with the Mane 6 and the princesses

anyways, you had bumped into your friend, Pinkie Pie, she had another pony trotting alongside her, her expression immediately lit up

Pinkie Pie: Hiiiiiii bestie!!

The new pony looked.. unimpressed..

Maud Pie: Who.. is this?

Pinkie Pie: Oh! I've never introduced you guys! Maud, this is my human best friend! Best friend, this is Maud, one of three of my sisters! :D

Maud had lost interest and is now collecting rocks..
