Iron Cage

Iron Cage is a location in the Wooded Kingdom in Super Mario Odyssey. It can be accessed by entering a Painting found in either the Metro Kingdom, the Seaside Kingdom, or the Snow Kingdom, depending on the order the player decides to visit the kingdoms. The cage contains the Secret Path to the Steam Gardens! Power Moon and a Checkpoint Flag. Two platforms that break when they are stood on are also found, allowing the player to have access to the rest of the Wooded Kingdom from the Iron Cage.
