Complete the Donut Secret House

Star World and Bowser Castle

Use the cape in Star World 4 to glide under the row of gray blocks to the keyhole. Get the key out of the Mystery Block by whacking it with the cape.
Step5
Go through rooms 2 and 8 in the castle. Light up the dark room by hitting the block near the first stairway and head for Bowser.
