The Legend of Zelda: Tetra's Trackers was formerly planned as stand alone game, but ended up being released as a minigame on the japanese version of The Legend of Zelda: Four Swords Adventures (Four Swords +), as Navi Trackers. In this game, multiple players, using a combination of the television screen and Game Boy Advances, search for members of Tetra's pirate gang to gain stamps from them, as many as possible within a given time limit. All action takes place on the Game Boy Advance used by each player, with the television screen showing a basic map, and Tetra narrating the action. Before becoming part of the Zelda series, it was first intended to be a remake of BS Marvelous: Time Athletic, as verified by a leftover model left in the final game.
