Gas pipe

Gas pipes are hazardous obstacles that are small tubes that emit poison gas in a constant stream, or, in some fanon games, at regular intervals. Some are embedded within bramble gates or stick bridges. As they constantly emit poison, White Pikmin, which withstand poison, generally must be used to deactivate them, by attacking them. Alternatively, some enemies can be used to deactivate them.

In Pikmin V
Gas pipes are indestructible objects in Pikmin V. They have had a visual update, becoming metal pipes arcing just out of the ground that have holes in them that the gas leaks out of. The only way to deactivate the pipe and allow passage is to find a valve to shut off the gas flow.
