Khndrel Keght

The Khndrel Keght (also referred to as the Dirt Slime in the config and code) is a hostile mob added by Ender IO Zoo. It is a special version of the Magma Cube. It has a 20% change of spawning when a Dirt block or a Grass Block is broken without a proper tool. Each attack will inflict points of damage if it is small,  points if it is of medium size, or  if it is large. When a Khndrel Keght is killed it has a chance (which can be altered in the config file) of spawning another one that is larger in size (small to medium, medium to large).

While only the small version of the Khndrel Keght will spawn through breaking dirt, hitting a small Khndrel Keght with dirt has a small chance to spawn a medium sized one. The Khndrel Keght's spawn egg will randomly spawn any size Khndrel Keght.

In versions for Minecraft 1.12.* the Khndrel Keght drops a lump of Clay but no experience when it is killed.
