Carmine (Full name Carmine Angelica Crush Pie) AKA Firebug by a select few- is the daughter of Human!Pinkie Pie and Pony!Sunset Shimmer. She’s a ball of energy and a complete spazz, but is surprisingly not insane.
 
She inherited Pinkie’s weird exploding sprinkle powers, and uses the power to make some very interesting fireworks. Also, she plays the drums and likes crocheting, because why not? At a young age, her and a few others from the human world decided to go on an exchange trip, so to speak, to Equestria to learn about their culture, magic, etc; or in Carmine’s case- out of curiosity. She loved it so much that, as soon as she was old enough to, moved to Equestria and became a citizen of Ponyville. She visits her family constantly, and adores her parents very much. In fact, for awhile she considered them her best friends.
 
Carmine literally has an explosive temper, causing generalized mayhem whenever she’s peeved. She tries very hard to calm herself, but the only things that seems to help are crocheting, sweets (especially ice cream), and her friends/family. Perhaps what she really needs, though, is someone specifically trained to handle such things…
 
Also I love her design. Which is good, since I literally spent eight hours on it.  
Yes, eight hours.
