World 6-5 (New Super Mario Bros. Wii)

This level features Porcupuffers, tides and some large ? Blocks. The design of this course is much like the design of World 4-2. There's also a secret exit that is accessible using a Propeller Block or Propeller Mushroom, which will take the player directly to the World 6 castle.
