Shell Soccer

Shell Soccer is an extra minigame featured in Mario Party 9.

Introduction
The minigame first shows a view of the center of the arena, with the teams on both sides of the court doing an animation. The camera then pans toward the sun before showing the Koopa shell in the center, then zooms out.

Gameplay
Players are divided into two teams of two, which may be selected after the player chooses the characters. The teams are working together in order to eliminate the rival team's seven Goombas first.

Players automatically "dribble" the shell by making contact with it. The player may kick the shell or pass it to his or her teammate by pressing. If the player shoots the shell, it may ricochet off the sides of the arena. Passing or shooting also forces the player to stand still, giving rivals a chance to steal the shell, which can be done by pressing. When the player hits a Goomba with the shell, his or her team receives one point times the number of Goombas hit. The next round then begins, with the opposing team getting the shell.

Ending
The winners stand in the center of the arena, with the losers behind them, while confetti falls from above to commemorate their victory.
