Boss statues (alternatively spelled Boss Statues), also known as statues or gold statues, are four big golden statues with keyholes in Mario Pinball Land that are found at the entrance to the Fiery Stage. In order to progress, the player is required to insert a Star Key into each statue.
After defeating a boss and obtaining a Star Key, the player can hit the keyhole of the statue of that boss to insert the Star Key into it. This causes a red ! Switch to appear at the location where the boss was defeated. The player also receieves 100,000 points. Boss statues for which the player has obtained the Star Keys visually shine. After using all four Star Keys, the boss statues turn in the direction of the gate, and the gate opens.
If the player has obtained fewer than four Star Keys, using them sends the player back to The Fun Fair.
