Boonanza!

Boonanza is a Duel mini-game in Mario Party 6.

Gameplay
As in all Duel mini-games, for each player the whole point of the game is to beat the other one. The way to do it in this game is to round up as many Pink Boos as the player could into his/her piece of land. An easy way to do this is to chase the Boos up the corners that would lead to the player's piece of land. Whoever gets the most Boos in their piece of land would win.

Introduction
The introduction shows the 1st player chasing a lone Pink Boo. It would soon get away and all the other Boos would pop out of the ground.

Trivia
Boonanza is a pun off the word "bonanza".
