Bubble Weed

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

Utility
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 stuns all varieties of until it has run out of air. This interaction only happens when underwater.

Trivia

 * Bubble Weed was 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 drains both reserves simultaneously with no added benefit.
 * Slugcat can boost underwater without using up Bubble Weed faster.
 * If not held, Bubble Weed float to the top of a region gate during the heating part of the gate sequence.
 * Swallowing Bubble Weed allows for easier transport, especially through lightly flooded areas, as the reserves won't be used up while they're in Slugcat's stomach.
