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 Sphynx. As usual, he gives Mario a small set of questions. Answering one question correct opens up a doorway leading to a secret, hidden area.
