What Goes Up...

What Goes Up... is a 4-Player minigame in Mario Party 6 and Mario Party Superstars. The name of the minigame is a reference to the phrase "What goes up must come down," which is emphasized in both versions of the minigame. This is the only minigame in Mario Party 6 that plays different music between day and night. Only the daytime version appears in Mario Party Superstars.

Introduction
In the daytime version (and in Mario Party Superstars), a cloud platform takes the leading player to the starting point, where they leap off the cloud as the screen splits in four.

In the nighttime version, three balloons lower each of the players to the starting point. When the minigame starts, the balloons pop.

Gameplay
Between day and night, the minigame's objective is different. In the daytime version, the players must climb higher into the sky with the help of clouds and Koopa Paratroopas within 30 seconds. Hitting a Paratroopa instead of jumping onto it sends a player downward. Whoever reaches the highest point wins. Any players who tie for first win also, unless all players tie.

In the nighttime version, the players must fall a distance of 200 meters/yards to reach the platform at the bottom first by avoiding Paratroopas and clouds.

In Mario Party 6, the daytime variant of the minigame appears as the second minigame in Decathlon Park. Here, the player's objective is to climb as high as possible to earn as many points as possible, up to 1,000. The default record for this minigame in Decathlon Park is 100 meters/yards.

In Mario Party Superstars, the minigame retains the record system from Decathlon Park.

Ending
In the daytime version (and in Mario Party Superstars), as soon as the minigame has ended, players are suspended in their current positions by balloons. The losers'/loser's balloons then pop, and they fall as the winner(s) perform(s) their victory animation(s). If no one makes it up high, they instead sulk.

In the nighttime version, as soon as a player wins, the others are suspended in the air by balloons. The victor then performs their winning animation as the losers' balloons pop, sending them plummeting toward the ground. If they were close to the ground, they land and do their losing poses.

Trivia

 * While the nighttime version is still called "What Goes Up...," the demo version of Mario Party 6 that could be played in stores separately referred to it as "Must Come Down!"
 * Because the music track for this minigame changes depending on the time of day in Mario Party 6, this is one of only two minigames in the Mario Party franchise to have a version that has a different music track in the same game, the other one being the Mario Party version of Hot Rope Jump, where the "Full of Danger" music plays in the Mini-Game Island version, instead of the usual "Let's Limbo."
