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

World 8-7 is a secret level in World 8 of New Super Mario Bros. Wii. This level can only be accessed if World 8-2's Secret Exit is completed. 
== Overview ==
This level features the Bonecoasters' first and only appearance, and is populated by several Lava Plumes. 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.
== Walkthrough ==
Mario starts the level in a lava-filled cavern where he must jump on a Bonecoaster, which later leads to another Bonecoaster. The Bonecoaster leads Mario to a Warp Pipe, which leads to an above-ground area with the midway point and to another Bonecoaster. After three more Bonecoasters, the flagpole awaits at the end. The Bonecoasters often make risky maneuvers, passing through Lava Plumes and the lava itself.
==Star Coins==
*Star Coin 1: After boarding the second Bonecoaster, 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 Plumes, 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 Bonecoasters that are ridden simultaneously. Mario and co. must ride the lower Bonecoaster to it, then immediately jump up to the higher one, obtaining the Star Coin and avoiding the Lava Plumes.
