There are three smaller plateaus below it that you can use to reach the ledge. Shortly after the mid-level save point, you’ll come across a large floating mass in the sky with a tiny ledge just visible at the top of the screen. Make sure you don’t lose him during the level, as you’ll need his help to gain entry to the warp cannon. You’ll make your way through the level and eventually find a ? box containing your old pal Yoshi. The game’s first warp cannon entrance is located in World 1-3. New Super Mario Bros Wii is no slouch in this department, as there are several secrets for careful explorers to unlock.

No Mario game would be complete without a multitude of unlockable warp cannons.
