Clover

Clover is a three-leaved plants used as scenery in all Pikmin games. It can be seen in numerous overworld locations, but it's particularly common on "rest levels" inside several caves.

In the first two games, although clovers do not directly affect gameplay, disturbing a clover patch can often scare Iridescent Flint Beetles out of hiding. Some small insects may also fly out. In Pikmin 3, leaders and Pikmin can hide under clovers and other tall plants. Finally, in, the clovers in Downpour Thicket provide protection from the droplets of dew that fall from the sky.
