Mario Speedwagons

Mario Speedwagons is a 4-Player minigame found in Mario Party 4 and Mario Party: The Top 100. Its name is a pun on the name of the American rock band. If the player reaches the goal in under 10 seconds in Mario Party 4, they unlock Boo's picture frame in the Present Room. This is the only minigame in Mario Party 4 to have no music (other than the "Let the Race Begin" jingle) and one of only two minigames in Mario Party: The Top 100 to have no music, the other being Don't Look.

Introduction
The camera zooms across the speedwagon each character controls. Then, the screen splits four ways, showing the rear of each character's vehicle. The traffic signal flies in, and after the "START!" signal (3–2–1 countdown in The Top 100), the signal's lights turn on. When the green light flashes, the race starts.

Gameplay
The goal is to be the first one to cross the finish line in a. Each participating character drives their own, complete with unique coloration (player color in The Top 100). Along the way, the car's gears will need to shift as it picks up speed. This is indicated by the gear numbers flashing in the bottom right corner (Touch Screen in The Top 100). However, correct timing is required, as early or late shifts will result in a decrease in speed or no increase in speed, respectively. Likewise, accelerating too quickly at the start can cause the car not to move very much, like in the Mario Kart series.

This is also the third game in Mario Party: The Top 100's Decathlon.

Ending
At the "FINISH!" signal, the screen with the winning player zooms in, with the player's wagon having a parachute flying off it. After that, in Mario Party 4 only, the scene changes to the winner podium, where the players are in their respective positions. The winner does their victory pose, and the losers do their losing poses.
