Paradoxx

This is what I think pinkie would look like if it was up to me in the show lol...
She's biologically female, but she loves all and is willing to date multiple people. She has 6 children total.

Close-Up of Melody's Cutie Mark.
It's a two mirrored bridge eighth note shaped balloon.
It represents her love and talent for Music as well as Partying.

I remade my old Pinkie Pie next gen child. The child is with Vinyl Scratch, cause I believe they work well together.
I kind of also head-canon that Pinkie Pie is Polyamorous, only because she goes well with so many characters, such as:
Party Favor, Cheese Sandwich, and Vinyl Scratch/DJPon3.

My pinkie pie next gen child was named Minty Surprise originally, but I renamed her to Melody Joy. She is the next element of Laughter.
