Animals Fury

Gameplay Loop
When you spawn in a new world your first focus should be to immediately get a weapon, as the animals wont wait for the night to arrive before attacking. So now you have to do the things you usually do in Minecraft while avoiding getting ambushed by an Animal.
The Cure
It is possible to craft a Cure. When cooking rotten flesh and thereby getting leather, you unlock a new crafting recipe that can be fed to any animal to cure it from the disease.

Note
It is not possible to play this Datapack in Peacefull mode for technical reasons, and the difficulty will be switched easy if you load up the world as Peaceful.
