Rainbow Notes are multicolored notes that first appear in Super Mario Galaxy and usually only appear when Mario finds a Question Coin. The ones in Gold Leaf Galaxy will only appear after Mario rings the bell. They will then line up and Mario will have to grab them all in order to collect an item from it. They will make different sounds and form a jingle of a classic Mario tune. They can also be used to get a star like in Hurry-Scurry Galaxy, Gold Leaf Galaxy, and Sea Slide Galaxy.
