Snowfall Mountain is a winter-themed court in Mario Tennis Aces.

In-game description

 * "A bustling square in front of the train station. Keep a close eye on those Shy Guys, who will hide among the commuters and hit the ball back!"

Adventure Mode
Mario and Toad arrives at the fourth area they visited. A Penguin told Mario and Toad that cannot board the train because the Shy Guys took control of the train. If they get rid of the Shy Guys, they can resume their schedule to their trip. After defeating the Shy Guys, Mario, Toad and the Penguin climbed on board to Snowfall Mountain. After their discussion with the player, a Shy Guy realizes that they are trying to reach the summit and challenges Mario into a tennis match. After the match, Shy Guy informs about the treasure. He even mentions that a Shy Guy informed about the snow ogre and added that is why they stole the train; they are shy but not "heartless". He tells them to go to the summit and investigate. There are two optional missions: Shy Guy challenges them to return twenty-five balls without Shy Guy hitting it three times, and Mario must hit the panels until he reaches 800 points within 200 seconds to earn the Ice Racket. Mario and Toad reach the summit for the third Power Stone and faces the Snow Ogre, the third boss. After defeating the Snow Ogre, the sky turns dark and the ice pillars disintegrated and the Koopa Troopas and Shy Guys. A hole appears after completing the mission. They saw the airship that they took to go to the island which presumably Waluigi, Wario and Luigi who are fused by Lucien took it. They travelled to Savage Sea for the fourth Power Stone.
