World 8-7 (New Super Mario Bros. Wii)

 is the secret level in World 8 in New Super Mario Bros. Wii. This level features the Spine Coasters' first and only appearance, and is populated by several Lava Geysers. There are no enemies in the level. Unlike World 8-2 and World 8-3, this level uses an edited version of the default underground background.

Layout
Mario starts the level in a lava-filled cavern where he must jump on a Spine Coaster, which later leads to another Spine Coaster. The Spine coaster leads Mario to a Warp Pipe, which leads to an above-ground area with the midway point and to another Spine Coaster. After three more Spine Coasters, the pole awaits at the end. The Spine Coasters often make risky maneuvers, passing through Lava Geysers and the lava itself.

Star Coins

 * Star Coin 1: After boarding the second Spine Coaster, the first Star Coin is floating just above the lava. Mario and co. must obtain it by jumping at just the right time.
 * Star Coin 2: After the midway point, the second Star Coin is floating next to two lava geysers, and must be obtained by jumping over them.
 * Star Coin 3: The third Star Coin is floating in between the two tracks of the two Spine Coasters that are ridden simultaneously. Mario and co. must ride the lower Spine Coaster to it, then immediately jump up to the higher one, obtaining the Star Coin and avoiding the Lava Geyser.

Trivia

This level was going to be an autoscroll level. This was changed because the screen moved too fast and the Spine Coaster could not keep up with the screen.
