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 this minigame, "In Calm Water," is a cover version of the Super Mario Bros. Underwater Theme.

Introduction
The minigame starts with a clam onscreen. It then spits out the Red Team members in their Cheep Cheep submarine. The screen then splits, showing both teams.

Gameplay
The minigame consists of two teams of two players, who must race to the finish by riding Cheep Cheep-shaped submarines, one red and the other blue. The upper half of the screen shows the Red Team, while the lower half shows the Blue Team, and the divider contains a small straight line that shows how far each team is from the goal. The players must reach the goal by taking turns pumping the lever to accelerate their submarine; if a player gets tired, their movement rate will visibly slow down. Players should switch places at appropriate times in order to maintain their submarine's pace and prevent either one from becoming extremely tired, though it is possible to reach the goal quickly without switching at all. The first team across the goal wins.
