A shay jeff is a very retarded entity that can be found wandering around on mnecraft servers hitting random blocks and has a disturbing skin of a human in the front and pure white on all other sides. If you have every encounter this rare being you are very lucky and can easily take advantage of his completely stupid actions such as wandering around in random directions breaking blocks occasionally and will try to attack you but fail miserably due to not having armor or any weapons, and he will keep coming back to attempt to kill you at random times but never will succeed.
Hey! Is that a shay Jeff!?!? Lets attack him and he what he has on him.
