Bonus Round
Go to Stage 6 (Ghost Castle.) At the first room don't go up the stairs, instead go to the place near the rabbit and you'll see a locked door near a crown. Get the crown then open the door. Go in to the room and you get to play a round of pool.
Note: You need at least 50 Crowns to get into the door.
