In Pikmin 4: Curse of Astromountain
The Glowstool is an uncommon enemy found in only three underground areas. They light up dark areas with their bioluminescence, acting as a large, walking Common Glowcap. They're harmless, and they steer clear of other enemies so they're not a big bouncy blockade.

In Pikmin: Dual Worlds
The Glimmerstool is a rather uncommon species of Sporovid that, rather than producing spores like most other members of its family, instead merely produces Light. It's harmless on its own, but can be somewhat of a nuisance. It may wake up sleeping enemies my walking in front of them due to their glowing.
