| NiGHTS into Dreams|
Soft Museum, called The Confusion at the beginning of the game, is the third dream of Claris Sinclair in NiGHTS into Dreams. This mysterious world was created from big changes that Claris wasn't ready to and swayed her. It is set in an European-style garden with a strange museum that isn't solid. The museum's walls can be used like a trampoline. This world's boss is Jackle.
Soft Museum appears as the fifth pinball table in Sonic Pinball Party, the boss of the table is Jackle.
- In Amy Rose's version of the level Twinkle Park in Sonic Adventure, there's a mirror room section which is very similar to Soft Museum's mirror section, where the player must look at the mirrors to see hidden details in the level.
