Rainbow Dash's dream of joining the Wonderbolts.
Yay! I ponified something!
Seriosly, I got like a huge doze of Nostalgia when re-discovering this series. Also, the show's protagonist, Molly, made me think of Rainbow Dash somehow.
Anyway, for those who won't get completely confused by this, enjoy ;D
For the rest of you, google "Oban Star Racers"... I feel very European for liking that series...
