Submarathon

Submarathon is a 2 vs. 2 minigame found in Mario Party 5. The name is a portmanteau of the words "submarine" and "marathon". The song, In Calm Water, is a cover version of the Super Mario Bros. underwater theme.

Gameplay
The mini-game consists of teams of two players each who must race to the finish riding Cheep Cheep-shaped submarines.

Simply enough, the first team to reach the goal is the winner. To do this, players can take turns. While a player uses the lever (and makes the submarine move), the other rests. Once the one using the lever gets tired, evidenced by that player slowing down the rate at which he or she can pump the lever, he or she changes positions with the other player. This way, none of the players gets extremely tired and can cooperatively work to get to the goal. However, it is possible to reach to the goal quickly without switching the players at all. The team who gets to the goal first, wins.

The screen is divided in two. In the upper half, the red team pilots a red-colored Cheep Cheep submarine. The blue team controls a blue Cheep Cheep submarine in the lower half. In the middle of the screen is a small, straight line which shows how far each team is from the goal.
