Bubble

Bubbles are a hazard that appear in the Pikmin series. After being blown, they gently rise into the air, eventually popping if they last long enough. Pikmin and leaders can become trapped inside of them, but they both can be freed if the bubble is made to pop or pops on its own. A trapped leader can also struggle to cause the bubble to pop prematurely. Winged Pikmin can pop bubbles most easily because of their ability to fly.

In fanon games, bubbles can be filled with a fluid such as water or be made of a substance such as oil.

In Pikmin: Wide World
Bubbles appear in Pikmin: Wide World as a rare hazard. Any Pikmin or leader that touches one will become trapped inside of it until the bubble pops. Bubbles pop once enough time has passed or Pikmin are thrown at them, and leaders can pop a bubble they are trapped inside of by struggling enough. Popping a bubble is done most easily using Winged Pikmin because they are able to fly. Although small bubbles can often be seen underwater, they are purely cosmetic and do not affect gameplay.

Aquatic Cannon Grubs may blow large bubbles as a secondary attack, which can trap several Pikmin and leaders at once. Peckish Aristocrabs may spit up bubbles to defend themselves with. Lastly, Waddlepi may release a multitude of bubbles from the pores on their back.
