Silver Spoon was a very wealthy pony from a rich family, almost rivalling that of her best friend, Diamond Tiara. She was logical, privileged, quick to point out one's flaws, and one of the best-behaved fillies in Ponyville following the day when the Cutie Mark Crusaders earned their Cutie Marks.
However, when said well-behaved filly comes across a massive silver spoon rooted into the ground that no-one can pull out, she takes a hold of it and becomes the newest evil to ever plague Equestria.
NIGHTMARE SPOON!
