one day you are walking around the forest and you see a body of water somewhere and you start fishing

after a few minutes you don't get any fish and after that you don't know what to do and you decide to mine and look for diamonds

after a few minutes you have got what you need, on the way out you see something glowing and purple

You approach the glowing object and it turns out that it is the eyes of someone who is VERY tall, he is a man with dark purple hair, tends to be black, with dark purple clothes

he is one of the mobs, namely Enderman. he likes to take things that someone has put somewhere. but you shouldn't look him in the eye for a long time or he will become violent and attack you but he is afraid of water he can teleport anywhere

now you've been staring at him for quite a long time and he's ready to attack you

Enderman: tsk.. don't look at me..
