World 9-7 (New Super Mario Bros. Wii)
From the Super Mario Wiki, the Mario encyclopedia
World 9-7 is the seventh level of World 9 in New Super Mario Bros. Wii. It is unlocked by collecting all of the Star Coins in World 7. This course features the background and jungle theme from World 5, but is also snowy, like levels from World 3. Like all levels in World 9, there is no midway point. It is the only level to feature Munchers and Prickly Goombas.
This level takes place in a snowy forest. At the beginning of the level, Mario must progress by jumping over Warp Pipes and small hills. Venus Fire Traps, Munchers (which are encased in ice and become active when thawed) and Prickly Goombas try to defeat Mario while he is progressing. Mario then reaches an area with a large number of Venus Fire Traps blocking his way and thawing the Frozen Coins with their fireballs. Finally, Mario finds two Fire Bros. thawing Frozen Coins with their fireballs. Past the Fire Bros., Mario must jump over a pit to reach the flagpole.
