NiGHTS into Dreams
Soft Museum is Claris' third level and it is only available to be played after clearing Mystic Forest.
The museum's walls can be used like a trampoline and the player can get many points by bouncing on the museum walls and doing tricks.
The Nightopians and Mepians sculpting statues of NiGHTS is behavior exclusive to this level. Other than that, they can be seen doing all of their common behaviors (singing, dancing, rolling, walking, whistling, clapping, making bubbles and fishing cake).
Sonic Pinball Party
Soft Museum appears as the fifth NiGHTS thematic table in Sonic Pinball Party. The boss of the table is Jackle.
