Gas pipe

A gas pipe.

Because this subject has no official name, the name "Gas pipe" is conjectural.

Suggestions: Add locations, more images, explain how non-Whites and Gatling Groinks can destroy these.

The gas pipes are hazard sources from Pikmin 2. As the name would indicate, they are small tubes that emit a steady stream of poison gas. They can usually be found in caves, although they are present in the overworld as well, commonly placed inside bramble gates or bridges, functioning as a means of only allowing White Pikmin to be used to break down the gate. However, two thirds of the gate can still be taken down with non-Whites, by throwing them on top of the gate and having them break the wall down from the top.

The pipes can be taken down with non-White Pikmin as well. For this, one must throw a Pikmin directly onto the pipe. Although uncommon, the Pikmin will sometimes land a hit before starting to choke. From this point, the Pikmin can just be whistled back, and the cycle can repeat until eventually the pipe is gone. It's also possible to bait a Gatling Groink into attacking the pipes, which will destroy them. This can only be done on the gate after the lake in the Wistful Wild.

Trivia

The gas pipes on the areas will respawn 99 days after being destroyed.
Gates containing gas pipes can normally be attacked by all Pikmin (even though non-Whites will choke). However, if the player hasn't unlocked White Pikmin yet, then it will be impossible to attack those gates, except the ones found in the Wistful Wild. Without White Pikmin, the gas pipes can still be destroyed by a Gatling Groink, and to be able to destroy the gates afterwards, the player has to end the current day (since the gas pipes will have disappeared on the next one).
