World 8-3 (New Super Mario Bros. Wii)

World 8-3 is the third level of World 8 in New Super Mario Bros. Wii.

Layout
The level starts out in a cavern full of lava. Throughot Mario and company must contend with giant lava waves that will defeat them upon contact. Hanging over the lava are chained platforms that sink when one of the characters step on them; these platforms can be found throughout most of the level's first half, with Koopas and Paratroopas placed on or around them. Shortly after the checkpoint is a series of tunnels that require the heroes to weave through incoming lava waves to pass safely. Following the tunnel is a series of weighted platforms that also sink if weight is applied to them. Fire Chomps guard the area. At the end is a Warp Pipe that takes players to the level's flagpole.

1-up trick
