This guide shows you how to find every Newspaper, Schematic, Baseball Card, Comic, and Figurine hidden in the tunnels and sewers in Cheeseball Sub.

The Ticket Booth and Broken Floors

Once you get to the first train, turn your body around and grab the Ticket Booth Key from the crate. Walk along the train tracks and unlock the door on your right. Follow this path to the end.

You will find a Newspaper on a table in the room with the lights and a Schematic on a bunk bed in the room to the left. Later, when you reach a room where the floor is broken, jump up the boxes to reach a higher spot. Walk past the wooden fence to find a Newspaper sitting on a box.

The Timed Lock and Locker Room

After you climb up to the second set of tracks, turn left and use your tail to pick the lock on the door. You are on a timer for this task. If you are too slow, the lock jams and you must restart from your last save in MOUSE: P.I. For Hire.

If you succeed, go through the door and follow the path to the locker room. A Baseball Card is hanging on a clothesline on the right side of the room.

Suspended Trains and Sewers

Look for a large room with a train car hanging in the air. Look at the windows of the small room in the top left. Break a window and jump up inside, then shoot the explosive barrel to blow a hole in the wall.

Follow the path through the train until you hit the platform, then turn left and jump into the tipped-over train to find a Schematic. After you climb a small ladder into the sewers, enter the second room. A Newspaper is on a box immediately to your left.

Boss Arena and Toxic Water

In the area where you fight The Boss, jump to the very top of the cargo crate in the middle. You will find a Comic on the metal grate near the edge. After that, you will reach a second section of water where you have to glide.

A Schematic is on the lower section at the end. Stay out of the water because it deals a lot of damage. To leave, use a Double Jump into the updraft to start gliding again.

Hidden Tunnels and The Figurine

Go through the vent and pick the lock on the door in front of you. Jump into the water and follow the tunnel at the bottom to find a safe with a Schematic. Go back to the main room and hit the lever to turn on an updraft. Glide up and land on one of the platforms.

Find the explosive barrel on top of the train car and throw it at the breakable wall. This opens a secret room where a Figurine is sitting on a shelf in MOUSE: P.I. For Hire.
