Rainbow Mario

Rainbow Mario is a special form of Mario that appears in Super Mario Galaxy and Super Mario Galaxy 2. Mario can reach this form by obtaining a Rainbow Star. It makes Mario invincible, much like the Starman, but the effects of the Rainbow Star are more extensive and longer-lasting than those of a Starman. As Rainbow Mario, the heroic plumber runs faster, leaves a light trail behind him, breaks through certain objects, and is rewarded with Star Bits if he doesn't stop moving.

Rainbow Mario's theme is a re-orchestration of the classic invincibility theme. The music as well as Mario himself will increase in speed while in use, making Mario harder to control until it runs out.
