Hole (Super Mario Odyssey)

Holes, also referred to as archer ports and archer's ports, are objects that appear in the Bowser's Kingdom in Super Mario Odyssey. They are small openings in the walls, some of which are open. When Mario captures a Pokio, he can use its beak to poke inside the open hole, rewarding him with a Power Moon.

According to the brochure, these holes were previously used by defenders to shoot at invaders.
