A black poison gate in the Wistful Wild.
Gates are obstacles in both Pikmin games that block paths to other areas. They are found in a number of different forms, which require different strategies to overcome. In general, they can be destroyed by Pikmin: a captain just needs to order them to work on the structure, by throwing, swarming or disbanding them. As time passes, a gate that is being destroyed lowers in three distinct stages, finally collapsing to the ground with the standard 'completion sound'. The length of time it takes to demolish a gate depends on its type, and the number and types of Pikmin working on it.
