Bubble Weed

Bubble weed are green plants with blue bubbles filled with oxygen found in aquatic regions of Rain World, particularly Drainage System. Holding these plants underwater uses them like oxygen tanks, providing 20-30 seconds of air before the slugcat's own reserves are used.

Function
Bubble weeds show they are providing oxygen by releasing a stream of bubbles underwater. During this process, each bubble on the bubble weed is exhausted individually, until the entire plant is dark and wilted. When found in the world, bubble weed are often found attached to the ground, with all bubbles filled. When thrown, these plants have tendency to float high before descending slowly to the ground. Bubble weed are buoyant enough to float on the surface of the water.
