Twipie. Twinkie Pie. Pinkie Sparkle(…?) you know, the ship of Twilight and Pinkie.
 
Their foal is called ‘Fortune Biscuit’, is an unicorn and his cutie mark is a rocket as a falling star :3
 
Fortune Cookie loves his moms so much. He calls Pinkie ‘Pink-mum’ and Twilight ‘Twi-mum’.  
Regardless of it, in his inside he knows that he’s jelaous of Twilight because as an alicorn she can fly, and he considers her dummy for not use this ability to travel the sky and explore new undiscovered places in Equestria, what it’s his dream.  
His relationship with Pinkie Pie is good, even if she acts so childish or hugs him too tight.  
His personality is very analistic, a bit serious and only smile sometimes, but when he does is with his heart. He is very clever and dreamer.
 
“It’s not like I care about not having wings, that’s not the problem, and of course I don’t blame Twi-mum or Pink-mum for it, it’s just… that the power, the magic… that’s not for me. My mind begs me for fly and dissapear between the clouds, being on my own, my personal heaven. But this horn that I have on the middle of my forehead forced me to keep my hooves in the ground, wishing to be a flying creature, that’s my fate. My name should be ‘Unfortune’.”
