Bulb Berry

The Glimmer Bulb Berry is a new type of Berry for Yoshi in Super Mario Galaxy 2. The berry appears as an inverted glowing light bulb with a yellow stem on it. The Glimmer Bulb Berry gives Yoshi the ability to light up hidden paths, similar to the bouncing matter in Matter Splatter Galaxy from the first game; this power-up is known as Bulb Yoshi. It seems to have a time limit, much like the Fire Flower.
