After the Events with Tirek and the box that became the seed of friendship, Discord took it upon himself to give Twilight a better present than a key that was once a medallion.

He gave her the Earring's of Profound Change.

It was said in the Journal of Star Swirl that these earrings allowed one, if the right statement is said whilst wearing them, they would spend an allotted amount of time as something other than pony.

This is the story of how Twilights once boring life literally took a turn at the road of Banana's and Crazy town, but maybe she could live with it.
