Silly Sprout is one of the New Mane 6 in My Little Pony: Equestria's Heroes.
Silly, as her friends call her, is the descendant of Pinkie Pie. She inherited the money of the cake family, and opened an orphanage from young ponies. She wishes to become an entertainer. Not much of her backstory, other than that, is known.
Silly is slightly older than the other ponies, but is still the silliest, as her name implies. Her cutie mark is a decorative piece of wheat. She represents the element of laughter. This is shown when a sick child at the orphanage refuses to smile, but Silly's Song cheers him up instantly.
