We had an entire episode dedicated to giving the mane six their butt symbols, but so many ponies throughout Equestria remain a complete mystery. Why does Bonbon have a Bonbon? What is the significance behind Derpy's bubbles? It remains a mystery!
Have a task: A new episode is planned for season five called "Cutie Mark Chronicles 2", where six background/incidental pony are going to have their sonic rainboom inspired marks explained. Pick your ponies, and if you have some time, give a short description on each of their origin stories.
