Comet Medal

"Collect many Comet Medals? Comet arrive. First time in galaxy... Always one Comet Medal somewhere! Look hard. Find!"

- Whittle

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 usually found 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.

Trivia

 * When collected, the Comet Medal makes a similar sound effect to that of a Red Coin from Super Mario Sunshine.
 * They were originally thought to be known as Comet Metals due to a mistranslation.
 * Comet Medals have a shape that is almost identical to the shape of the Bowser Space from Mario Party 6.
 * Star Coins, which will appear in the upcoming Super Mario for the Nintendo 3DS, feature a design similar to that of Comet Medals.
