Loco Motives is a Duel minigame that appears in Mario Party 8. Its name comes from "Locomotive". It features a train set.
In this minigame, the two players are controlling toy trains and are tasked to avoid popping their own balloons with the trains. The trains will lose their ability to move when they pop a balloon. When the train is touched, they will change direction. The players must be careful not to pop their own balloons which will score a point for the other player. The player whose opponent's balloons pop first (often three points) wins. Balloons will eventually regenerate and gain their spherical form at which point their train starts moving again. This costs the owner's opponent to lose a point.
