So, I was playing against someone online. He kept choosing Rainbow Road and it keeps getting picked. I notice while racing, as I was often ahead, I would hear the hopping sound of my opponent's kart. I'm thinking, what's that for? So he glides in air, giving him speed leverage? By the way he was using Princess Peach with her pink kart. Then, when he finally got to me with all the crazy hopping, I noticed he was flying??? What the heck is that?
