Where to Find It
Chapter
The Sewer
Location
The half-pipe area after the code door, where exploding balls must roll freely.
Step-by-Step
- Turn the catwalk valve handle to rearrange the rear half-pipe, then pull the switch to open the wall pipe cover.
- Upstairs: turn the first valve twice, push the middle button, turn the second valve twice.
- Break the boards with your knife, pull the switch to open the lower pipe cover.
- At the four-button panel: pull the left switch, then the right switch (opens both pipe covers).
- Press the buttons in sequence: 1st, 4th, 1st, 3rd. The half-pipes align across from the buttons.
- Let an exploding ball roll to the fingers blocking the water tunnel — they open. Enter the tunnel as they open.
