Bubble Weed

Bubble Weed or Bubble Grass are green plants that have oxygen-filled bubbles at the tips of their branches. Bubble Weed is found in the aquatic regions of Rain World, especially Drainage System, but also. These plants act as oxygen tanks underwater, providing 20-30 seconds of air before the slugcat's own reserves are used.

Function
Bubble Weed releases a stream of bubbles underwater, indicating extended breathing time. During this process, each bubble on the plant is exhausted individually, until the entire plant is dark and wilted. When found in the world, Bubble Weed plants are often found attached to the ground, with all bubbles filled. When thrown, these plants have tendency to float upwards before descending slowly to the ground. Bubble weed are buoyant enough to float on the surface of water.

Bubble Weed will also stun nearby Leeches momentarily.

Tips and Trivia

 * Bubble weeds were added to the game in the 1.5 update.
 * Two individual stalks of bubble weed can be held at the same time, but doing so underwater will drain both reserves simultaneously with no added benefit.
 * If not held, bubble weeds will float to the top of a region gate during the heating part of the gate sequence.
