The Comet Medal is one of the main items in Super Mario Galaxy 2. It allowed a Prankster Comet to enter the galaxy that Mario had collected the Comet Medal in. The Medals also appear in Super Mario 3D Land. However, the function is unknown.
The Comet Medals could be found throughout all of the galaxies in Super Mario Galaxy 2. They are usually located in secluded or hard-to-reach areas, far away from where the majority of the level is played. They can usually be accessed through a power-up that Mario or Luigi can use, or through objects surrounding their location.
Despite there being a Comet Medal located inside of every single galaxy, there is not always a Prankster Comet for each area. However, the Medals are required for 100% completion of the game.
