Star Chip

"I HAD a Launch Star all ready for you, but a meteor smashed it up! You can't leave without it, so find all the Star Chips to fix it."

- Luma

Star Chips are items that appear in Super Mario Galaxy and Super Mario Galaxy 2. They always appear in sets of five, obviously representing the five points of a star. When Mario collects all five of the yellow pieces, a Launch Star will appear. There are also blue Star Chips in addition to the regular yellow ones. Blue Star Chips are far less common, though they do prove integral to the successful completion of several levels. When all five are collected, they create a Pull Star. Sometimes, upon completing a set of yellow Star Chips, several Pull Stars will appear in addition to the Launch Star. When the first Star Chip is collected, a small icon representing the Launch Star (or Pull Star) will appear at the top middle of the screen, and will gradually be filled up in a clockwise direction as Mario collects more Star Chips.

Super Mario Galaxy
* - Levels containing blue Star Chips.

Mario Tennis Open
Star Chips are found in Mario Tennis Open. They appear exclusively to Galaxy Rally, a Special Minigame. If the player hits one with the ball, the player collects some coins while filling a Launch Star meter. When the Launch Star meter is full, the Star Chips stop appearing, and a Launch Star is formed. After a certain amount of time, the Launch Star disappears and the Star Chips reappear.

Trivia

 * In the Supermassive Galaxy, there are several platforms toward the middle of the level that are shaped like gigantic Star Chips.
