Cell Block and Water Room

Once you get to the area with the cells, walk into the Control Room. You will find the Ze Orders Clue right there on the desk. Later on, you will find a room that has water everywhere.

Get in the water and move under a bridge to reach the middle section. There is a Schematic sitting on a crate in MOUSE: P.I. For Hire.

The Brain and the Jar-Head Gun

When you get to the room with the Brain, look at the board to grab the Schematic. After the Jar-Head Gun is in your hands, head through the door and wait for a Warp Pipe to appear.

Go through it and you will see a Comic on a Wheelchair. Climb up the ladder after that. Another Schematic is on a table next to the door.

Laundry and the High Balcony

Walk out of the Laundry Room and enter the Warp Pipe. Go through the door on your left. You need to get onto the pipe and jump across to the other Warp Pipe. Check the cabinets by the door to find the Baseball Card.

When you reach the Balcony at the top, jump onto the roof over the center space. The Schematic is waiting in the Safe in MOUSE: P.I. For Hire.
