Trapdoor (Mario Pinball Land)

Trapdoors are objects in Mario Pinball Land that appear in the shipwreck of the Frosty Frontier Stage and in the boss rematch room of the Fiery Stage. These are wooden objects with white targets that are placed on the left and right sides of the room. Hitting a trapdoor reveals a cannon, which shoots a single cannonball bomb. Cannonball bombs are required to defeat Porcupuffer. After that, a trapdoor closes. Cannonball bombs can also hit it. Hitting a trapdoor grants 3,000 points.
