Post your homebrew worlds

[D&D_Fan]

An example of a room in bagworld:

There is a room with an elevator that is deactivated.
There is a box on the wall with 5 levers.
The levers are labeled in English, but not Common.
They have to figure it out through trial and error.
Players take off the box.
The first lever (red) activates a robot.
There is a smaller lever for the robot to push when activated.
The robot is activated.
It refuses to push the lever.
The party pushes the smaller lever.
It makes the robot go forward and deactivate the lever again.
Second lever (blue) turns off gravity.
They quickly reactivate that one.
Third lever (yellow) turns off lifeform lock.
The wizard is now a dolphin.
They reactivate the lifeform lock.
The wizard is now trapped as a dolphin.
They deactivate the lifeform lock again.
The wizard is now an American Chestnut Tree.
They get him back to being human.
4th lever (white) activates the elevator.
They push the 5th (black) lever out of curiosity.
It turns off all DM narration.
That stopped the game until they reactivated it.

Other:
They had potions in jello and hypodermic needle format.
They also converted all of their gold into USD.
In the train subdimension, they wanted to buy food, but all money was souls.
They tried to get a man with multiple personalities since he would have multiple souls or something.
The surviving personality was evil and stole their food.
There was a hotel on the train subdimension that took peanuts instead of souls, but it was replaced by a rollerblading rink.
The wizard became a god of mayonaise.
Really.

Classic fun.
