The Castle map contains many secret areas.

The disco floor.
Disco Room
In the water below the largest ship in the Port quadrant, there is a gap in the water located at (−19, 62, 103). Opening the trapdoor and descending the ladder beneath reveals a room with a rainbow-colored floor and two large speakers. A stand is in the back of the room with a record player.



The golden whale.
Golden Whale
Behind a stack of hay bales in the Farms quadrant at (38, 76, −64), a descending ladder leads to a small room with a table and a chair (consisting of a door and trapdoors). Opening the door reveals another hidden ladder. Descending it leads to a whale made of gold blocks. The whale is partially submerged in water, making the room a viable fishing spot.
