World 8-2 (New Super Mario Bros. Wii)

This level contains more falling debris and spinning wheels on the ground. As soon as Mario and co. enter the pipe, they end up in an underground area filled with more lava. Goombas and Paragoombas will appear many times on this stage, along with the spiked balls. The team have to dodge the obstacles to get through. However, there is a secret exit; after the Mario team passes a yellow and a red pipe, they will see more spiked balls rolling forward slowly. Right at the ledge, if the team drops down and heads left to the wall, a secret entrance will allow them to enter a pipe further if they keep heading right.

Once gone into the pipe, the team will see that the ground is spinning very fast. They have keep jumping until the end of the ground. They must also watch out for Goombas that appear on the spinning ground. Once they get through, they'll open up the secret exit to 8-7.
