Spine Coaster

Bonecoasters are rideable creatures made of bone used to make Mario and his company pass through the lava pit. They only 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.

Bonecoasters are very useful throughout World 8-7 because they help Mario and his friends get the Star Coins in this stage and also prevent them from falling into the lava. However, the Bonecoasters often make risky maneuvers, passing through lava geysers and into the lava itself. Bonecoasters can stand the weight of Mario, Luigi, and both Toads on it. However, if all characters perform a Ground Pound over it at the same time, it will fall, making everyone fall into the lava. Also, Bonecoasters can not hurt any character.

Bonecoasters have also appeared in the Wii U demo New Super Mario Bros. Mii shown at E3 2011. One is seen in a dark cavern that is filled with poison water, carrying Mario and friends once again.

Bonecoasters later appear in Super Mario 3D Land. However, they only make the appearance in 2
