Navi Trackers (formerly planned as a stand alone game titled Tetra's Trackers) is a minigame found only on the Japanese version of The Legend of Zelda: Four Swords Adventures (Four Swords +). 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.
