Tube It or Lose It

Tube It or Lose It is a 1-vs-3 minigame found in Mario Party 5, Mario Party: The Top 100, and Mario Party Superstars. The name is a pun on the phrase "Move it or lose it!"

Gameplay
The solo player controls a spiked machine, while the three members of the team each control an inner tube, which is faster and more maneuverable than the spiked machine. As the players travel through the course, the solo player must collide with the team members, popping their inner tubes and eliminating them. Along the way, rocks, tree stumps, and ramps are encountered. The solo player can break these by colliding with them, but the team must maneuver around them. Also, jumps in the course can be used strategically by the players to avoid or hit the others. If the solo player can eliminate all three team members before the end of the course is reached, the solo player wins. If even one team member survives to the end, the team wins.

In Mario Party 5, every character has their own tube colors when they are on the team side (see the section below for variants), while in Mario Party: The Top 100, the team tube colors are instead based on player order (red for Player 1, blue for Player 2, green for Player 3, and yellow for Player 4). In Mario Party Superstars, all of the team tubes are colored black, regardless of character or player order.

Tube colors (Mario Party 5 only)

 * Mario – red and blue tube
 * Luigi – green and blue tube
 * Peach – pink tube
 * Daisy – yellow tube
 * Wario – yellow and purple tube
 * Waluigi – indigo and black tube
 * Yoshi – white and green tube
 * Toad – white and red tube
 * Boo – white and cyan tube
 * Koopa Kid – orange and green tube

Ending
In Mario Party 5 and Superstars, the players are shown standing in front of a log cabin, with the winning side in front of the losing side. If the solo player wins, they will be seen in front of their spiked machine and celebrate while the team players sulk behind them. If the team players win, it is the inverse; they will be seen in front of their respective remaining inner tubes and celebrate while the solo player sulks without their spiked machine.
