Pinball digital counter

The Pinball Block is an object in the Game Boy Advance game Wario Land 4. It only appears in the level Pinball Zone. It is a block that guards the door to the next room. Ithas a digital face that counts down how many Pinball Slots remain in the room. Wario must throw a Pinball in each of the four Pinball Slots. They have a mouth which opens and closes on regular intervals, determining whether or not the Pinball will enter the slot. If a Pinball is correctly placed in a Pinball Slot, the slot will disappear and it will drop a 50 Coin. With every Pinball Slot filled, the digital number on the Pinball Block will decrease by one, beginning from four. When it reaches zero it will flash briefly and disappear, dropping a 500 Coin and granting access to the door, which will lead to the next room in the Pinball Zone. There are a total of six Pinball Blocks amongst thirteen individual rooms in the level.
