Comet Medals are a type of item that appears in Super Mario Galaxy 2. They are white octagonal coins with a golden lining and a picture of a golden comet imprinted on them. Collecting enough Comet Medals will make Prankster Comets appear, like the Prankster Comets in the first game. They are found in the first mission of every galaxy, usually in hard to reach places or requiring the use of a power-up. Once collected, if the player re-enters the level, the Medal will appear to be a clear blue silhouette of the original. It can still be collected, however. It will temporarily be added to the total, but as soon as the level is completed, the total will revert back to its previous value.
There are 49 Comet Medals total, but not every galaxy will encounter a Prankster Comet, even after every Comet Medal has been collected.
Comet Medals also appear in Puzzle & Dragons: Super Mario Bros. Edition. They raise the Skill levels of both forms of Rosalina and all types/forms of Cheep Cheeps and Bloopers from levels 1-4, while Grand Comet Medals raise from levels 5-7.
