D64 castle

Koopa's New Fortress is an area in B3313.

Description
This is a small area with walls lined with dark metal, and filled with water and Goombas. The water level is set low enough that the Goombas create loud splashing sounds as the water rises and lowers. The music here is a rendition of the castle theme, seemingly played with low metal banging sounds (please change this if you know the name of the track).

There's a room with a Bowser Painting and a black painting, both unenterable, and a well with a grate leading to a Red Star. Another area is a flooded stairwell with two podiums, each changing the water level to their position when Mario interacts with them. This stairwell also has an Ultimate Box. At the bottom of the stairwell is a door to the room with the Red Star. Under the stairway leading here from Rainbow Rooftop, there's a doorway with the doors blown off and laying flat on the floor.
