The next room houses a mini-game like stop and go. This mini-game tasks you with making your way across the room while the lights are dark. If you move when the lights are on you will get eaten. As you go through the room about mid-way there is a slide selection. Go through the Hard Slide to get the PJ-Pugapillar (6). At the end of the course hook up to the window to smash through it into the control.

In the control room there is a hole in the floor. Drop down through this hole. Walk forward and swing across the gap to the other side. Continue forward on the other side and look up at the end of the hallway. Grapple to the floor above. Walk forward through the next section and grapple up again. Walk forward again and look for a vent on your left. Crawl inside the vent and go through it. Go forward and grapple up again. Follow the path forward up the stairs to reach the Water Treatment plant.
