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
"There's no escape. The only hope is the sweet relief of death."

- Lumalee

Lumalee appears in The Super Mario Bros. Movie and is the only Luma that appears in the film. In the English release of the movie, Lumalee is voiced by Juliet Jelenic, the daughter of the movie's co-director Michael Jelenic. Some of his sound effects, however, are reused voice clips of Lumas provided by Yuya Takezawa. Jelenic explained in an interview that her voice was recorded as a placeholder, but was ultimately used in the final release as they were unable to find actors with a voice that provided the desired dissonance.

Lumalee is one of Bowser's captives, alongside Luigi, the Penguin King, some penguins, and some Goombas, as well as the Kongs later on in the film. He has a child's voice and a somewhat twisted and nihilistic personality. The Penguin King tells Luigi to ignore him and that he is "cute but [cuckoo]." He is shown annoying the other prisoners, especially the Penguin King, with his cheerfully suicidal demeanor. He exclaims that time, like hope, is an illusion and that death is the only escape from their imprisonment. The Lumalee is later excited to die in the lava at Bowser's royal wedding along with the other prisoners, but he is freed from his imprisonment by Mario and Donkey Kong, which visibly dismays him. After the ending of the film, Lumalee appears and tells the audience that since the film is over, all that is left is them and the "infinite void." He then plays the Super Mario Bros. Ground Theme on a saxophone to start off the end credits music.

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 third and final trailer.

Trivia

 * In the Japanese versions of Super Mario Galaxy and Super Mario Galaxy 2, Lumalee's dialogue does not make reference to the Luma species or its own name, instead singing,「ピカリン」(pikarin), an expression that suggests something flashy.
