Lumalee

The Luma Shop.

The Luma Shop is a traveling "shop" in Super Mario Galaxy and Super Mario Galaxy 2 that sells helpful items to Mario. 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, Lumalee will appear in a pipe that is at one ear on the Starship Mario. The first Lumalee needs 30 star bits to turn into a Chance Cube. The second Lumalee needs 100 coins to turn into 5 chance cubes.

Trivia

• In the Super Mario Galaxy trading card, it says the Luma's name is Lumalee. It is unknown if this is official.
  • However, in the ear of Starship Mario in Super Mario Galaxy 2 there appears to be two Lumalees, suggesting that there's not the same Luma hosting the Luma Shop.
• When the Hungry Luma asks you what you would like to trade your Star Bits for, in Super Mario Galaxy, only the icons were shown. In Super Mario Galaxy 2, 1-up and Life are shown too. This might be because players might not know what the mushrooms actually do.
