Star Key (Mario Pinball Land)

Star Keys are collectible keys that appear in Mario Pinball Land. A Star Key is dropped by the boss of each of the first four stages in the game after they are defeated, meaning there are four Star Keys in total. Collecting a Star Key earns the player 100,000 points. If the player does not lose a life, every Star Key collected after that earns them 100,000 more points than the previous one. To enter the Fiery Stage, Mario must insert a Star Key into each of the four boss statues to open the gate in front of Bowser's castle.
