Smarty Pants

Smarty Pants is Twilight Sparkle's old doll from when she was the Cutie Mark Crusader's age.

She is first seen in a blue and gold chest when Twilight exclaimed that she was going to create a friendship problem.

Later, Miss Smarty Pants is used to try and create an argument between the Cutie Mark Crusaders, so that Twilight may solve it and send in a friendship report.

When that does not suceed, Smarty Pants becomes a main part of Lesson Zero when Twilight enchants the doll with a 'want it, need it' spell making all of Ponyville fight over it.

The doll is abandoned by most of the ponies when Princess Celestia intervenes and lifts the spell, but Big McIntosh, showing a genuine want for the doll, runs off with it.
