Multi Moon

Multi Moons are collectable items in Super Mario Odyssey. Equivalent to the Grand Stars in Super Mario Galaxy and Super Mario Galaxy 2, they are usually collected after completing a level with a boss (with the exception of Bowser) or another story-related mission. They count as three Power Moons when powering up the Odyssey, although they are only counted as one on the list of Moons in a kingdom. Like the Power Moons, the Multi Moons are given specific colors depending on the kingdom in which they are found. Collecting a Multi Moon will teleport Mario back to the Odyssey.
