that was no fresh cloud it was a green fart cloud warning you that you may need to slap towards the toilet.
The excersize yard and shower I saw as two function. Cleanliness increase from shower and aggression reduction from exercise . The other feature was it was two areas you would bring the convicts together. This gives aggressive convicts a chance based on aggression. To attack the other inmates therefore needing monitoring and a slap to stop a different death possibility.
I was going to have a soap option in shower you can rub over showerers and get bonus cleanliness.
Those were the thoughts and I was going to make it when you click the button you can pick up to 4 again needing balance and monitoring to give the right ones what they need. I was going to teleport them there as my skills didn't feel there for more flashy response and movement.
