Clog

A clog is an obstacle that resembles a cracked rock, blocks some cave entrances or other holes in those caves, and plugs holes underwater so that areas remain flooded. They can be destroyed with Pikmin; often, only Blue Pikmin are able to approach them due to them being submerged. By destroying an underwater clog, a hole is uncovered, draining the water from the surrounding area.

In Pikmin: Shipwrecked Stargazers
In Pikmin: Shipwrecked Stargazers, a clog can be found on the seabed of Creature's Quay. Destroying it, with Blue Pikmin, will drain the normally changing water levels to a point where all Pikmin can cross any pathway in the area.
