Pick up the CLOCK on the right and walk towards the castle in the back.
On thw wall is a dowsing rod. Try to take it and Ow of the El will get if for you. Talk to the Ow and ask for the rod. You can have it if you get his car from Room III. Use the door to get inside the castle. Walk towards the north and use the door to the interview room. Talk to the interviewer to receive a PEN. You’ll get the assignment to get the book.
Use the door to Pit I and put the pen in the bin. You’ll get the BATTERIES out. Leave the slinky, it will get you in trouble later on.
Don’t enter Pit II as it will cause your death. Use the door to Pit III. Use the lightbulb to distract the fat man and pick up the BOOK. Also take the CAR and leave thr room on the left. Return to the interview room and give the book to the interviewer. He tells you to destroy the stained glass window and to do so you need to visit room IV. You get the code for this room.
Walk to the south to leave the hallway and give the car to Ow. He tells you to destroy it so put it on the track to let the train run over it. He’ll give you the DOWSING ROD. Use the door to go inside again.
In the hallway use the pin pad next to door IV. Put the battery in the pin pad and enter the code Z, Square, I and IIII. [Note: this is not as the interviewer told you! The last character is IIII, not III]. Use the dowsing rod on the floor to find a DETONATOR. Leave the room and return to the interview room. Use the detonator on the window and use it again to destroy the window.
Then tell the interviewer you’re not ready for the interview. Use the window to jump out.
