Plunder Island - Secret Star Block

After the midway gate, you will see two groups of ascending platforms. Climb the second of these to reach a Triangle Switch. Activate the switch and continue to the right beyond the Star Block, using the Triangle Block to reach a springboard. Bring the springboard into the first yellow pipe to the left of the Star Block to find the secret exit.

Mario Becomes Lunch - Keyhole

The keyhole is located to the right of the blue pipe that takes you to the second area.

Davy Jones's Locker - Solution

The Flame Blocks in the ship area will turn on or off the candles in the background, brightening or darkening the area. Different paths are accessible depending on which setting the candles are on.
