I am currently making another adventure map about the events before this one. But because it won't be realeased for a while heres a quick explanation of what happened.

There was a scientist who loved mushrooms. She loved them so much she wanted them to know how much she loved them. She did an experiment on one of her favorite mushrooms, Barry. The experiment both succeeded and failed. It succeeded because the mushroom came to life. It failed because the mushroom grew huge and became evil. The mushroom broke out of the lab and destroyed a city. A hero was sent to stop it and succeeded. They captured it and kept it in prison until it escaped again.

I will fix this in the next update, thanks for telling me.
