Super Horn

Finally, a way to stop the all-mighty Spiny Shell! _ quote from Mario Kart 8 trailer

A Super Horn is a new item introduced in Mario Kart 8. It can be obtained in any position, though it is the hardest item to obtain in first place. When players use it, it emits a large shockwave generated from sound that can flip out nearby racers and destroy items, including Spiny Shells, within its radius. It looks similar to both the Light Box and the Cannon Box from Super Mario 3D World.
