Boss Keys are special miscellaneous items found throughout the Newer Super Mario Bros. series. They appear after most end-world bosses, allowing access to the next world.

Appearance

Boss Keys are large shiny golden keys with horns on their held end.

Behavior

Boss Keys will jump out of most end-world bosses on their defeats (excluding Bowser and Dry Bowser), usually landing on the right side of the arena. On touch, the player will be able to open a door to the next room, often revealing Princess Peach being taken to the next world.
