Coming into contact with these "plants" can cause Bomb Rocks to drop from the ceiling in certain caves. This is relatively easy to cause on the 5th sublevel of the Subterranean Complex. If attempts are unsuccessful, run around the sublevel running into each Glowstem after it has already been cleared of bomb-rocks and Volatile Dweevils. At least one bomb-rock should be triggered by the Glowstems. This can happen with either the red or the green variants of Glowstem, as both appear in the sublevel. This makes Glowstems a somewhat easy way to scout out bomb rocks in caves with them.
"Although they are obviously unrelated, the glowstem bears a striking resemblence to the street lights on Hocotate. It is highly possible that glowstems could be a relic of some unknown civilization beyond the scope of our imagination."
"Inedible. Known effects include uncontrollable episodes of impromptu break dancing."
- It's scientific name, Nocturnica illuminati, means 'nocturnal illuminate'. Nocturnia is close to nocturnal, and illuminati is close to illuminate.
