This is a tribute to the Rainbow Roadtrip. Rainbow Dash may not have been invited to the celebration that she was expecting, but she managed to adapt to the situation. Sunny Skies doesn’t have a whole lot of field experience in comparison so it was a lot harder for him to get on with the program. He doesn’t have any fancy super powers either so there’s no way he can stop Equestria’s fastest flyer. Rainbow Dash won’t be going down so easily. Rainbow Dash wins.
