Inside the Cage

Into the Cage is the sixth mission of Dire, Dire Docks in Super Mario 64 DS, replacing Collect the Caps... from the original game. This mission requires Luigi and his Power Flower ability.

Layout
Luigi needs to make his way to the boardwalk in the second area. He then needs to collect his Power Flower from the red ? Block to turn invisible and swim down to the cage under the large hole to the south. Inside the cage is the Power Star, but Luigi needs to swim inside quickly before the Power Flower's ability wears off.
