Mario Kart 8's new features include anti-gravity racing, in which certain parts of a track can allow racers to drive on walls and ceilings. During these sections, players can bump into other racers or special bumpers to trigger a Spin Boost, which gives them an extra speed boost. New characters include the Koopalings, Baby Rosalina, and Pink Gold Peach. There are four new items: the Boomerang Flower, which can be thrown to attack players, the Piranha Plant, which attacks nearby racers and obstacles, the Crazy Eight, which gives the user eight items, and the Super Horn, which can be used both to attack nearby opponents and defend against items, including the previously nearly unavoidable Spiny Shell. The game features 32 tracks in eight cups (Mushroom, Flower, Star, Special, Shell, Banana, Leaf, and Lightning), with an additional 16 later released as downloadable content (DLC) in four additional cups: Egg, Triforce, Crossing, and Bell.
