Stretch Plants are rubbery balloon-shaped plants that appear in Super Mario Galaxy and Super Mario Galaxy 2. They can also be called Rubber Bulbs due to their bulb-like appearance. Mario can use his Star Spin on them to send their bulging end flying out. However, these bulbs boomerang back to the plant's root, causing Mario to lose some of his Star Bits if the plumber is caught in their path. However, if an enemy collides with a Stretch Plant, Mario will not lose Star Bits upon getting beaned.
