This is Apple Crumble, the accidental son of Pinkie Pie and Big Mac. He was conceived at Pinkie and Cheese Sandwich’s wild and drunken wedding reception. He lives with his father on the Apple farm but frequently visits his mother at Sugarcube Corner. He’s an abstract painter, and for awhile he tried to hide his talent from everypony fearing no one would understand his passion for specifically abstract paintings that other ponies made fun of because it just looked like “a whole lot of nothing”. But of course his parents were very supportive of his talents even if they didn’t fully understand it.
 
Having been raised within the Apple family, he’s not bitter about the circumstances of his birth like his half brother, Camembert. Crumble was raised with plenty of family to love and support him and he’s grown to be a calm and wise stallion like his father, but very optimistic (almost to a fault) like his mother.
