I've made a new world! I actually made this for Carbonfest on Carbon Combat so it could be used during the Cagematch event, but the world obviously also works here!
It's called the Cagematch world; here's a picture preview!
There is a big cage in the middle of the world, surrounded by a force field, in which the cagematch will be taking place. Positioned around the cage, there are two big screens that will display LIVE what is going on inside the cage, so that the spectators of the Cagematch event will be able to see. There are also a few boats in a lake, and an exciting easter-egg trail that runs through the world!
