Oil

Oil is an element found in the Pikmin game series, and found in many, many Fanon games. Oil is usually found in the form of slicks splattered on the ground. When Pikmin walk onto the oil, they will uncontrollably slip and slide as if walking on ice. Black Pikmin will not be affected by the hazard though, so their use is recommended in areas with oil in them. Oil on its own is harmless, but it can make your Pikmin easy targets.

Some enemies also utilize oil as a weapon, for instance, the Splattering Wollywog leaves behind oil puddles when it hits the ground. Black Pikmin generally should be used against oil-wielding enemies.
