Rubble

Rubble refers to small rocks strewn about the ground in a loose group. When Pikmin pass over rubble, whether directed to by the leader in charge or not, they will begin attacking the pebbles until none are left. Each pebble has a chance of inexplicably releasing nectar when destroyed.

In Pikmin: Attack of the Breadbugs
Rubble appears in Pikmin: Attack of the Breadbugs, and serves the same purpose as nectar weed, providing nectar. It is found at the Toxin, Marsh, Arctic, and Inferno Territories of the Land of Wonders and occasionally in Dangerous Depths. An unlimited number of Pikmin can be set to work on rubble at once, and Captain Olimar can destroy rubble by punching it.
