How to Find

C-1

ComBooter

Warehouse (F1)

Go to the eastern side of the Warehouse and grab the red ribbon spool. Place it on the unthreading device to reveal ComBooter, the first Boo in this mansion.

C-2

Bootine

Quarry (B2)

Before filling the Quarry with sand, gamers can find a ruby gem at the bottom. However, after filling it, they'll be able to find a Boo. Once you're at the top of the sand-filled Quarry, use the Dark-Light Device on the western side of the room. This will reveal a wooden bridge, which allows players to reach the other side and open a chest that hides Bootine.

C-3

Boodonkulous

Kiln Room (F2)

Go to the Transportation Hall after crossing the beams in the Roundhouse. Then, turn left and enter the Kiln Room - the Boo will be there waiting for you.

C-4

JamBoolaya

Clock Tower Gate (F1)

Using the Dark-Light Device, scan the wall crack next to the clock tower gates.

C-5

Boony Raboot

Crank Room (B1)

There is a hidden compartment on the southwestern corner of the Crank Room. Pull the curtain hiding it in the fall and enter it. Then, flash Dark-Light on the southwestern corner of the room to reveal a toolbox, where Boony Raboot is hiding.

Boos in Old Clockworks have a total of 30 HP, so in order to save time trying to lower their health, gamers might want to upgrade the Poltergust 5000.
