The Most Useless Bridge In The World
We do not know why this bridge exists. There is simply no good reason for it to be there. You are not supposed to make a bridge over the ground because it is going to be useless.
In general, bridges are placed over a body of water. This allows people to get from one end to the other. Now, it would be fine if the pool went through it. That is not the case, however.
Too Close For Comfort
Considering the way that they placed the toilet around the room, it seems impossible that they will all be used at the same time. After all, the space in this toilet is a little too small to accommodate ten users.
If they planned on making the most uncomfortable toilet in all of mankind, they did that. Congrats.
