You'll need the hammer
ability for this level. A quick way to get it: The
Yogurt Yard arena, or from Bonkers in the beginning of
6-3.
When you get to the part with Waddle
Dees on a bunch of blocks (after the block passages),
don't smash the blocks! Instead, only smash the first
two so you can smash the Waddle Dees as they come out.
Jump on the blocks, and then jump and use the hammer to
smash the blocks above. You'll be able to access the top
right door, which leads to the switch!
