Twilight isn't great at dancing. Spike knows it. Her friends know it. Even the poor souls who witnessed it first hoof on her birthday party in Canterlot knows it. But that hasn't stopped her from enjoying herself while "busting a move". So when Twilight receives an invite to a party being hosted by DJ Pon3, she eagerly accepts.
However, she's more than aware that everypony finds her dancing skills lacking. To solve this and impress everypony she decides to do a little research on the subject.
In the end she'll impress everypony alright, and it's not because she studied beforehand either.
