In Pikmin: Dusk and Dawn
Lumin appear in Pikmin: Dusk and Dawn as the first Pikmin type to be encountered. They are first found in the Verdant Vales by Captain Olimar. They are not able to be found during the day, only the night. Lumin are light blue, have even lighter blue-ish spots covering their body, beady glowing white eyes, and a glowcap replacing the leaf of their stem. They have no resistances but have the unique ability to root themselves into the ground, their stem growing into miniature Common Glowcaps, providing precious light that can repel creatures that lurk in the dark.

They are later found again in the Luminescent Caverns, along with their Onion. They are used to traverse the first part of the area, which is shrouded in darkness until a giant lightbulb is activated.
