=Boo Hunt= Boo Hunt one of the co-op challenges in Mario Tennis Aces.

Gameplay
(copied paragraphs from the Boo Hunt section in the Mario Tennis Aces article) Boo Hunt uses Swing Mode controls. In this event, players use tennis balls to hit Boos on the opposing side of the court to eliminate them, earning coins in the process. If the Boos reach the center of the court, they will steal some coins from the group total. Small mirrors that line the center of the court shoot tennis balls for the players to hit. Some Boos have an orange glow, and when a player hits them their next ball will be large, allowing them to hit more Boos at once. There are three stages, and when the group total reaches a certain threshold of coins they can proceed to the next stage when time runs out. Hitting Boos will also increase the Frenzy bar. When the Frenzy bar is filled up, Frenzy Time will activate. King Boo will appear and hover around the court, and all players will continuously receive tennis balls to hit him to earn more coins. He will disappear when either his health bar or the Frenzy bar is depleted.

Different stages have different hazards. Usually, the group of Boos slowly move towards the center of the court. In some stages, they assemble into set formations, and after the players hit the ball at them, they re-assemble into a new formation. Sometimes, the lights turn off, making it hard to see the Boos. Two glow-in-the-dark Boos also appear, and if a player hits one of them, they will be able to control their mirror to shine a light at the Boos that will halt them in their tracks. Other times, pieces of furniture will fly around the room, making it hard to hit the Boos, and Golden Mushrooms will appear, which can be hit to earn coins.

=Shy Guy Train Tussle= Shy Guy Train Tussle one of the co-op challenges in Mario Tennis Aces.

Gameplay
(copied paragraphs from the Shy Guy Train tussle section in the Mario Tennis Aces article) Shy Guy Train Tussle uses Swing Mode controls. In this event, players have to retrieve as many coins as possible from a band of Shy Guys who have stolen them and are trying to escape by train. To earn coins, players mut use snowballs to defeat Shy Guys (who are either on the train or around the train) or destroy the train's freight consisting of crates and barrels. Stationary cannons in the background shoot snowballs for players to hit. There are eight stages, and after the group total reaches a certain threshold of coins, they can proceed to the next stage when time runs out. Hitting Shy Guys will also increase the Frenzy bar. When the Frenzy bar is filled up, Frenzy Time will be activated once the current stage is cleared. Shy Guys will then jump in from the background, forming tall towers by stacking on top of each other, and all players will continuously receive snowballs to hit them to earn more coins. Defeating a tower of Shy Guys and destroying the crate on top of them grants players a key to opening one chest full of coins. Any remaining Shy Guys will leave once the Frenzy bar is depleted. Frenzy Time can be activated up to three times, and each time, one additional tower of Shy Guys is present for players to defeat.

Train layouts and Shy Guys tend to vary slightly between stages, constantly providing players with a different challenge when trying to collect coins. Shy Guys may come in singles or in stacks, as well as larger variants or shield-holding ones; the latter two variations require two hits to defeat them. Some Shy Guys float across the screen with the help of balloons and carry large amounts of coins in crates. Often, players will encounter different kinds of chests as part of the train's freight, which are opened on different conditions. For example, some chests require players to defeat a certain number and color of Shy Guys in order to open them, while other require players to uncover a key hidden inside of a crate.

Each stage also has a certain quota for players to achieve in order to earn extra coins. Once players fulfill a stage's quota, they will earn a large sum of coins which are added to the total threshold. Some crates hold large amounts of extra coins as well as power-ups such as Super Mushrooms, Ice Flowers, or Bob-ombs for players to use. The power-ups can be used to enhance the effect of their snowballs, with the Super Mushroom making the ball larger and able to destroy sturdier crates or barrels in one hit, the Ice Flower splitting the ball into four, and the Bob-omb being able to destroy a large portion of the train's freight.

A large Black Shy Guy appears as a boss in the fourth and eighth stages, wearing a yellow bandana in the former and a red bandana in the latter. Players must defeat him both times in order to successfully complete the Co-op Challenge. As players try to hit him with snowballs, he walks around while occasionally jumping to certain locations on or in front of the train. At one point, he throws Bob-ombs at each of the players which can be knocked back at him to deal more damage than usual. In the fourth stage, players simply have to deplete his entire health bar in order to defeat him. In the final stage, as they fully deplete his health bar, he initiates one final attack in which he throws a big Bob-omb that must be knocked back to him by all players in order to defeat him. Once he is defeated, he drops keys which unlock chests that completely fill the threshold of coins needed to complete the stage, thus signaling a successful end to the mission.
