Jump Block

A Jump Block (also known as a Music Block, a Note Block or a ♪ Block) is a type of bouncy block that helps Mario and Luigi achieve extremely high jumps. They first appeared in Super Mario Bros. 3, then in Super Mario World. In Super Mario Bros. 3, the Jump Blocks can be used to jump high (by pressing the jump button as the player is launched upward) and occasionally hold a power-up or Star for the player if he or she bounces on it or hits it like a ? Block. In Super Mario World, they serve the same purpose.
