Chunks

Star Chunks (commonly, erroneously referred to as "Star Bits") are common collectible items introduced in Super Mario Galaxy. They come in many colors (red, yellow, green, blue, purple, and white), and are quite shiny. In Super Mario Galaxy and its sequel, they give the player an extra life when a certain amount of them are collected.

They are also useful to facilitate bribery on James, as he will do anything for more.
