Clog

Because this subject has no official name, the name "Clog" is conjectural.

A clog is an obstacle used to block the entrance of caves and geysers and to plug holes underwater so that areas remain flooded. They can be destroyed with Pikmin; often, only Blue Pikmin are able to approach them due to their being submerged. By destroying an underwater clog, a hole is opened up that drains the water from the surrounding area.

Locations

• Valley of Repose; drains lake that gives access to the main part of the area.
• Awakening Wood; drains the small lake behind the ship, providing a shortcut.
• Perplexing Pool, plugging the entrance to the Shower Room; drains the pond with the Toady Bloyster.
• Wistful Wild; drains an area near the Burgeoning Spiderworts.
• In multiple caves, blocking entrances to the next sublevel.
