You must get out of that cell.
Pick up the BOOK from the floor and you’ll have the PAPERCLIP as well. Talk to the guard and ask why you’re here and what the place is. Look out the window to see what’s outside. Talk to the window on the lower right. Zork is there and after your conversation with him you know he’s afraid of water.
Leave the windows and look at your book. It’s a law book for prisoners. Keep looking at it until you reach chapter four about your rights and the right to go to the toilet. Talk to the guard and tell him you need to go. You can leave your cell and walk to the right into the toilet.
Look at the sink to find a COIN. Use the coin on the condom vending machine to get a CONDOM out and use the condom on the faucet of the sink to fill it up with WATER. Take the TOILET ROLL from the wall and use it on the toilet to block it. Use the toilet to flush it and cause a mess. Walk back to the guard and talk to him. You have to get into your cell first. Talk to the guard again and tell him about the blocked toilet.
While the guard is busy use the paperclip on the grated door to open it and walk over to the toilet. Push the guard into the toilet and pick up the KEY he dropped on the floor. Leave the toilet and use the door north to leave the cell. In the hall open the door to the locker room and take the SHOWER HEAD from the wall. Use the key you found on locker #2 to find a PORN MAGAZINE inside. Take it out and leave the locker room again. Use the staircase on the right to go to the level below.
Throw the porn magazine at the guards and they’ll be distracted. Pick up the utility belt from the floor to take a MAGNET and a WRENCH. Open door #1 and walk inside. Talk to Zork and ask him for his plate. You can’t have it. Leave the cell, go up the stairs and go back into your own cell. Look out the window and call Zork on the lower right. End the conversation and throw the condom filled with water at him.
Ga back inside and leave the cell. Walk back into the locker room and use the wrench on the ROD that held the shower head. Leave the locker room and go down the stairs back to cell #1. In your inventory use the magnet with the rod and use the combination to get the PLATE from the cell. There’s also a SPOON on it.
Walk north through the doorway and up the stairs on the right. Enter the locker room again and use the spoon on the broken floor under the shower. You’ll end up in the sewer. Walk to the left to the end of the tunnel and step on the plank on the left. Tie the shower head with hose to the flag pole and use the hose to climb down.
Open the lid of the crate and use the crate to climb in. Destination: mainland.
