Snowball Fight

Snowball Fight is the fourteenth mission in Mario Tennis Aces, taking place in Snowfall Mountain Station.

Mario and Toad enter Snowfall Mountain Station, where the Penguin conductor reluctantly says he can't take control of the train unless the Shy Guys controlling it would leave them alone. Mario agrees to help clear them out, though Toad warns him that Special Shots are not safe for the train.

In this mission, Mario has 180 seconds to clear out sixteen Shy Guys from inside and outside the train's passenger car, six Shy Guys from the train car with barrels, and eight Shy Guys from the train's main engine, mostly by rallying the snowballs the Shy Guys throw.

Afterwards, the Penguin thanks Mario for his help, and allows him and Toad to travel to Snowfall Mountain.
