From the Super Mario Wiki, the Mario encyclopedia
New Super Mario Bros. Wii
Spine Coasters appear in World 8-7 from New Super Mario Bros. Wii, a stage that can be unlocked by finding the secret exit in World 8-2. It also appears in multiplayer versus mode. Spine Coasters are the only method of transportation throughout the level, and they often make risky maneuvers, passing through lava geysers and into the lava itself. Players must time their jumps to avoid coming in contact with the lava and losing a life. Spine Coasters can stand the weight of Mario, Luigi, and both Toads on it. However, if all characters perform a simultaneous ground pound, it will fall.
Super Mario 3D Land
Spine Coasters (here called Bone Roller Coasters) later appear in Super Mario 3D Land, where they are only found in World 8- 2. Their design has changed into a three-dimensional figure, and also somewhat resemble Dry Bones. They also have horns.
New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
In New Super Mario Bros. U, Spine Coasters appear in two levels: the Rock-Candy Mines level Thrilling Spine Coaster, a course similar to the world shown in New Super Mario Bros. Mii, and the Superstar Road course, Spine-Tingling Spine Coaster. Spine Coasters and Spine Coaster tracks also appear on the world map, and can be used to travel between Frosted Glacier and Rock-Candy Mines. In New Super Luigi U, besides reprising their role on the world map, Spine Coasters appear in the levels Spine Coaster Stowaways and Spine Coaster Connections.
Spine Coasters reprise the aforementioned roles in New Super Mario Bros. U Deluxe.
