checked-part =>Hidden Cash: Use the vacuum on everything. Drawers, lamps, plants and more might yield cash. ->Large Diamonds: There are some special event diamonds that can only be earned if you complete certain challenges in the game. * Boo Diamond: Once you capture all 50 of the escaped Boos, you will be rewarded with a special giant blue diamond. * Plant Diamond: In the boneyard (behind the kitchen, with the dog ghost) you will find a small sprout in a planter. Before you use the warp in the dog house to battle the second boss (the ghost in the graveyard), water the sprout. After you beat the second boss, water the sprout again. Continue playing, but water it once more before you fight the third boss (all the Boos on the roof). If you water it all three times, it will bloom into a flower and give you another large diamond. ->Cheese & Golden Mice: If you suck up one of the small golden mouse ghosts, you will get lots of cash. If you find a wedge of cheese in a dark room, examine it with the Game Boy Horror to make a golden mouse ghost appear. These ghosts only appear in dark rooms, never in lit ones. Here's a list. * In the room with the Reading Ghost, look behind the desk. * In the 1st floor dining room with the Fat Ghost, look under the chairs. * In the 2nd floor dining room with the ice bucket, look near the back. * In the crystal ball/fortune teller room, look behind the fortune teller. * In the 3rd floor trophy room (with tigers), check behind the chairs. * In the 2nd floor hallway near the stairs leading to the attic, a golden mouse will appear at some point. When you hear a tone, grab the mouse. =>Hidden Mansion: Once you beat the game and save your progress, the mansion will reset so you can play through the game again. However, you will also have the option of trying out the Hidden Mansion. The only difference between the two mansions seems to be that the Hidden Mansion features tougher ghosts and a stronger vacuum. Whenever you load your saved game, you can choose between the Mansion or the Hidden Mansion. Any progress made in one is also made in the other, which means that it is really more of a Hidden Mansion mode than a unique mansion. =>Warp To Lobby: Want to return to the main lobby?
