Lumalee

The Luma Shop is a traveling "shop" in Super Mario Galaxy and Super Mario Galaxy 2 that sells helpful items to Mario usually right before he fights a boss. It is run by a turquoise Hungry Luma who holds the items for sale on sticks. The shop only sells 1-Up Mushrooms and Life Mushrooms, each for thirty Star Bits. After Mario feeds the Star Bits to the Luma, it will transform into the item that Mario has chosen. Because it transforms after purchase, Mario can only buy one item per appearance of the Luma Shop. In Super Mario Galaxy 2, by doing a certain mission, a Luma Shop will appear in a pipe that is at one ear on the Starship Mario. The first Luma Shop will turn into a Chance Cube for 30 star bits. The second Luma Shop will turn into 5 Chance Cubes for 100 Coins. Both Luma Shops' Chance Cubes have Star Bit, 1-Up Mushroom, Triple 1-Up Mushroom, and Quintuple 1-Up Mushroom spaces.

Trivia

 * In the Super Mario Galaxy trading card, it says the Luma's name is Lumalee.
