Stone spire

The stone spire is a large solid object that appears in the Cascade Kingdom of Super Mario Odyssey. When the Power Moon for the mission "Our First Power Moon" is collected, it drops down, breaking a piece of ground and creating a permament bridge to the rest of the kingdom.

Simular objects reappear in the Moon Kingdom, known as large pillars. While capturing Bowser, the player is required to break these four pillars so that they would fall on top of the structure in the middle.

Another pillar appears earlier, which breaks a wall and creates a bridge to the 2D section.
