Well uhh, with this mod you can... troll your friends by secretly adding this to your server.
You don't want to do that?
Well then uhh... I guess you can use this mod to make mining easier.
Just get some animals down in the caves and breed them!
What's that? You're not sure where to get the animals from because they explode when bred?
Well uhh... they survive the explosion, so you can have your animal farm in the cave that you're exploding!
