A-3 How to Get 3 Stars

These numbers are values we got based on our runs. If you got 3-Stars with better scores, take pride in it and share a picture in our Missions Record Boards!

1. Use the Crank in the Foyer
2. Investigate the Music in the Library
3. Clear the Library

Use the Crank in the Foyer

Once beamed into the mansion entrance. Make your way to the library using the crank from E. Gadd. Interact with the armor on the right side of the door, and collect the treasure for the upgrades on the Poltergust 5000. Get the Drop Amethyst before going forward.

Pass through the Guard Hall to get to the Foyer. Then check out the Coatroom. Interact with the coats to trigger the Gold Greenie to reveal itself. Capture it for a boost to your treasure count. Then interact with the table by the door to get a Golden Bone.

Head back to the Foyer and use the crank to lower the aquarium. Once the aquarium is lowered, continue north and investigate the music in the Library.

Investigate the Music in the Library

Head upstairs from the Foyer and through the Lobby where a couple of Greenies can be spotted. Once they are captured, face the elevator and wait for a Slammer and Spiders to appear. Charge up your Strobulb before the elevator arrives so you can flash the entire group as soon as they get off the elevator. Afterwards, vacuum the red poster to reveal a safe. Use your Strobulb to open it.

Afterwards, head into the Library. Dodge the books thrown by unseen enemies to get through the end of walkway towards the door. If you can, use the Strobulb on the golden enemies that spawn to increase your treasure count. Exit through the door and you'll find yourself in the Dining Room.

The Dining Room is filled with treasure. Be sure to interact with the curtain, table cloth, and chandelier to reveal all treasures in this room. Get the Stone Amethyst from a safe in the ceiling. Go to the Balcony on the south side of the room to collect some more treasure. Use the Strobulb to flash the bats and vacuum the gold brick. Head back in the Dining Room and interact with the hanging cord to reveal the dumbwaiter. Ride it to go drop down to the Kitchen.

Once inside the Kitchen, approach the stove to reveal an “armored” Greenie. Try to flash while it recovers from its spinning attack. Two more Greenies will spawn from the stove. It is recommended to deal with the “armored” Greenie first. There are lots of Hearts in the trash pile, consider taking it only after dealing with the greenies. Open the fridge to find a frozen Gem, then take it to the stove to melt the ice. Exit through the west door to go back in the Library.

Clear the Library

As soon as you enter the Library, the Piano-playing Poltergeist will show itself then vanish to ready its attack. The ghost will use the stack of books to hide itself, only appear just as it's about to attack. This is the right moment to stun with a Strobulb flash and wear it down with the Poltergust. Books will still be flying towards you as you struggle with the ghost, so keep dodging.

After capturing the Poltergeist, two more will appear. Use the same strategy to capture these two. Once all three Poltergeists are captured, answer the call from E. Gadd to complete the mission.
