Egg Marks are objects in Mario Pinball Land that can be used to make the Bonus Tower appear. Egg Marks are found in every area of the game (except in The Fun Fair) in the center of a special room. If a Yoshi Egg is used inside this room, a hole for the Yoshi Egg will appear underneath the Bonus Tower. The player then needs to use flippers to hit a Yoshi Egg inside this hole. This causes the Bonus Tower to extend upwards, revealing additional targets for Mario or Yoshi Eggs to hit, which lower the Bonus Tower and reward with coins. At the top of the Bonus Tower, there is a big golden Yoshi Egg, which can be collected for a large number of points.
