Quiet Wall

The Quiet Wall is a location in the Moon Kingdom in Super Mario Odyssey. It is a large cliff wall below Ever-After Hill and subsequently, the Wedding Hall. At the bottom of the wall is a large doorway leading to the start of the Underground Moon Caverns. In front of the doorway is a Checkpoint Flag. To the right are Binoculars. Further to the right is an Astro-Lanceur orbiting a crater with six regional coins above a Hat Trampoline.

Around the wall, to the right, is the Sphynx. Before Bowser has been defeated, his only question is 'Should you really be answering questions right now?' After Bowser's defeat, the Sphynx gives Mario a small set of questions as usual. Answering one question correctly opens up a doorway leading to a small hidden area containing a Power Moon in a treasure chest.
