In Pikmin Forever
Cobblestone walls are obstacles and a type of gate in Pikmin Forever. They are large smoothed walls composed of miscellaneous stones, however, their bonding agent is too absorbent to give way to bomb rocks. Only Lichen Pikmin can break down the wall, albeit gradually, and they break it down fluently: one stone is decomposed into soil at a time. The wall always retains its position and never fully crumbles, meaning that not every stone has to be decomposed to form a passageway; removing merely the bottom layer will suffice for Pikmin and leaders to pass under the wall. It is not advisable to leave a cobblestone wall in this state, however, in case Pikmin need to carry a taller object past it.
