Two players are trying to free Willy, which is a poor whale got stuck on the island. Each player has to maintain stability while standing on an unstable surface on one foot only!. Under this unstable surface a wiimotes (Wii Remotes) are installed, and we can track the movements and stability of the player. As much as the player can holds his stability, that will keep playing trance music with high volume to the loud speakers under a special containers (the pools) The beats frequency will perform vibrations in the water and causes the flagpole (that Willy is on the top of it) to sway and shake. Eventually, that should bring one of the player to free Willy!
