Open the Artifact Room Door
Use the keycard in the keycard reader at the Artifact Room door to start a puzzle that requires you to enter the correct code. The solution is a five-button code. Select the second button down on the first column and then choose the top button of the second column. The third button down on the second column and the second button down on the third column are also part of the code. Press the top button in the last column to open the door.
Fixing the Fuse Box
The fuse box in the engine room needs to be fixed, requiring you must solve a tricky. Attach the green wire to the XII socket. Connect the red wire to the XIX socket. Connect the purple wire to IX, join the yellow wire to VII and attach the blue wire attaches to XX. These connections will get the fuse box up and running.
Twinkle Twinkle
Once you place the sheet music on the piano, a puzzle begins. Use the sheet music to work out what tune to play to complete the puzzle. The solution is "CC, GG, AA, G. FF, EE, DD, C. GG, FF, E. D., GG, FF, EE, D., CC, GG, AA, G. FF, EE, DD, C," which turns out be "Twinkle Twinkle Little Star." Not all of the keys on the piano have notes written on them. Use this order of keys: "CDEFGAB." The music box opens at the end of the song. Take the broken stone from the box because you will need it later in the game.
Bathroom Differences
When you enter the bathroom, you must complete a spot-the-difference puzzle to continue. A items sits in the distance when you look out the window in the first picture, but it is not there in the second picture. The shells in the bottom left and top right corner of the screen do not appear in the second picture. Other differences are: the bench has no ornament, the bottom half of the crowbar is gone and the object poking out from the toilet lid is missing. The bird's head sticking out of the toilet is also removed in the second picture.
