Lumalee

A Lumalee, also named a Salesman Luma, is a cyan Luma who appears in Super Mario Galaxy and Super Mario Galaxy 2. A Lumalee's appearance is very similar to that of a Hungry Luma and Comet Tico, holding up signs depicting a Life Mushroom and a 1-Up Mushroom.

Super Mario Galaxy
A Lumalee serves as a "shop," where Mario (or Luigi) can purchase either a Life Mushroom or a 1-Up Mushroom for 30 Star Bits. Lumalees can be found in several galaxies and tend to appear before boss battles. Once Mario has made his choice of purchase, a Lumalee is fed the right number of Star Bits automatically and proceeds to transform into the mushroom of his choosing for him to collect. Because of this transformation, Mario can buy only one item from a Lumalee per appearance in that playthrough of the stage.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Lumalees serve the same purpose as in the first game. In addition, by doing certain missions, two Lumalees holding sticks with Chance Cubes on the end appear in a pipe that is on the left ear of Starship Mario. The first Lumalee turns into a Chance Cube for 30 Star Bits. The second Lumalee turns into five Chance Cubes for 100 coins. The possible outcomes from both Luma Shops' Chance Cubes are a single Star Bit, a 1-Up Mushroom, three 1-Up Mushrooms, and five 1-Up Mushrooms.

The Super Mario Bros. Movie
A Lumalee appears in The Super Mario Bros. Movie. He is one of Bowser's captives, alongside Luigi and the penguins. He has a child's voice and a somewhat twisted personality, as he mentions that death is the only escape from their imprisonment; the penguin king tells Luigi to ignore him and implies that he is insane.

A figure of a Lumalee appeared in a line of The Super Mario Bros. Movie toys released by as part of a Happy Meal campaign outside of Europe and Oceania. The release of this toy predated any official, explicit announcement of a Lumalee character appearing in the movie. The character was later revealed officially in the movie's final trailer. Outside of remakes, this marks Lumalee’s first appearance in any Mario media in 13 years.

On the official website for Super Mario Bros. Plumbing, inspecting the website's console output after visiting its faux 404 error page shows an version of a Lumalee.
