Shrek

Shrek is an easter-egg that has been added as an April fool on April 1st, 2014 when Mevans said that he would stop making the Lord of the Rings mod and would be transforming it into the Shrek mod instead (Link to the original post on facebook).

Shrek was actually in the mod ever since the Middle-earth terrain generation was released in February 2014, but he was not seen until the April Fool's post.

Shrek appears in the game as a troll with green skin. He spawns only in his unique house that lies in the Dead Marshes together with a donkey and a cat.

Behavior
Shrek has 100.000.000 HP so he is very hard to kill. Fortunaly he also is passive and doesn't fight back. He won't turn to stone through the sun as other trolls would.

The donkey and the cat also have the same amount of health and are not tameable.

Shrek's House
Shrek's House is a small wooden hut that is built in the bottom of a giant tree (around the size of the biggest Fangorn trees). This house is always generated at the coordinates X=76807, Z=51209, regardless of the seed.

Discovery
Shrek was first discovered by Thorren Buch at July 28th 2014 (original facebook post). For the discovery, Thorren got a middle-earth cape as a reward.

Code
The reason Shrek is green is hidden in the code. The code says that any troll named Shrek will be green. This does not happen normally, because Shrek is not on the normal list for Troll names.
