The Treasure Cards are said to give the possessor happiness and can make wishes and dreams come true. The Straw Hats, Vivi, and Ace decided to compete. Luffy and Vivi pair up together. Zoro and Ace, who were not interested in the treasure but their competitive sides are rubbed, so they join "just to win". Sanji followed Nami, who is joining for the treasure. Chopper was amazed hearing that Usopp had a plan. Thus, the teams were decided.

Game Modes

Treasure Battle

"Treasure Battle" is a (two-player-in-each) team game, and has players grabbing a treasure chest and putting it into a boxing ring at the end of each island level, then literally waiting for their ship to come in. Once their pirate ship arrives, that team wins. A team can throw the chest to each other over a limited distance, lob it in the direction they are facing over a greater distance, or even use it to attack the members of the opposite team who are doing their best to grab the treasure chest and take it back to their own boxing ring, and their awaiting pirate vessel.

The screen is split in the "Treasure Battle" according to how many human players are involved. In one-player mode, the full screen allows a decent view of the action, but the 2- and 4-player splits reduce the action to an extremely small view that can make it very hard to determine what is really happening.

Battle Royal

"Battle Royal" is a similar game to "Treasure Battle", except there is no chest and the arena is more confined. Each team just bashes the opposition about, as much as possible, for just under 3 minutes. All players are displayed on the full screen, which will zoom in and out depending on the spread of the action.

Kung Fu Survival

"Kung Fu Survival" both teams are placed on to a very small island inhabited by large numbers of Kung-Fu Dugongs. Whichever team beats up the most dugongs within the time limit wins. The player can walk right up to a dugong and attack it in the face, or if they choose Zoro they can have him attack with a kendo. The dugongs are basically defenseless, but if a player is standing motionless, may wander over and attack with a headbutt or flipper strike.

Team Work Rally

"Teamwork Rally" has each team passing the chest to each other across gaps that can't be jumped over whilst carrying the chest. The race to the finish is a careful balance between taking risks to get the edge over the opposition and being careful at other points to avert disaster.

Cross Country

"Cross Country" is an individual race to the end of each stage of a longer race. Each player gets a score based on their position at each intermediate stage and the team scores are totaled at the end of the whole race. The race is conducted along a series of different jumps, ladders, islands and narrow passageways.

Pirate Soccer

"Pirate Soccer" is pirates playing soccer. Except the ball is enormous and can crush the players if they fall under it. They have to use their attack moves to push the ball through goals at each end. Each half is 90 seconds.

Treasure Hunt

"Treasure Hunt" has players wondering around randomly until an arrow appears, directing them to hidden treasure.
