From TV Animation: One Piece Treasure Battle!
"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.
