A Big Bubble (also called Green Bubbles or simply Bubbles is an object that appears in Super Mario World.
Big Bubbles are large, green bubbles that can only be found in Ghost Houses in the game. In certain areas of a Ghost House, Big Bubbles often float randomly on the screen. Touching one directly causes harm to Mario. Big Bubbles are indestructible and, therefore, must be avoided. Also, Mario can Spin Jump on Big Bubbles to avoid taking any damage.
