Glowstem

The Glowstem is used for scenery in Pikmin 2. Glowstems appear to Hocotatian explorers to be relatives of the Common Glowcap, but in actuality, these tiny, orange lights are what are known as LEDs, or s. They are never seen above ground and can only be found in certain cave sublevels with a metallic layout. Despite the lack of insulation covering the live wires, Glowstems pose no electrical threat, nor any other kind, to Pikmin or leaders, and have been added to levels merely for aesthetic affect. Green variants exist as well.

In some caves, coming into contact with the "plant" will cause bomb-rocks to fall from the ceiling. When the player intends to begin the sublevel's exploration by scouring it alone, activating bomb-rocks, these plants provide a good indication of potential bomb-rock spots.

Trivia

 * The "Impromptu break-dancing" mentioned in Louie's notes on the Glowstem humorously refers to the convulsions brought on by being electrocuted.
 * In the Japanese version, the Glowstem's family is listed as unknown, instead of belonging to the glowcap family.
