Obstacle

A cardboard box in Pikmin 3, the first and one of the most basic obstacles found in the series.

To do: Check if Pikmin contribute to a task in a linear fashion or logarithmic fashion. i.e. do 50 Pikmin take exactly twice as long to take down a gate as 100, or are they faster? Check other obstacles too, and check all games.
Care to do so?

An obstacle is anything that stands in the way of the Pikmin and their leaders until it has been cleared or overcome. There are several obstacles of different types scattered across the areas of all games, and usually, the Pikmin must work together to clear them effectively. At times, obstacles do not block a path, but clearing them normally yields a shortcut or a reward of some sort.

Minor obstacles

Main article: Minor obstacles.

Several other obstacles appear throughout the Pikmin series; however, they are much more uncommon than the other ones listed above.

Trivia

In Pikmin 2, Pikmin that are attacking an obstacle while latched on will cause damage at a faster pace than those that are standing on the ground.^[1] This can be achieved with bridges by pushing the Pikmin off to the side and letting it go back to the bridge on its own, where it should hopefully cling on instead.
