Minecraft wiki entry for Enderman, associated text: An enderman can be provoked by a player or other mob attacking them. They can also be provoked by a player looking them in the eyes from up to 64 blocks then looking away. Endermen open their mouths and begin to shake‌[Java Edition only] angrily if provoked; they also make loud and lengthy sounds while being stared at. If the player continues to maintain eye contact, the enderman does not move, although it may teleport away. Once the player stops looking at the enderman, it runs toward the back of the player to attack, although it ceases if hit by another player or mob.[2] An aggravated enderman runs fast and often teleports to the location of a player or mob up to 32 blocks away (orthogonally). Endermen are not provoked by a player viewing it through a transparent block or while wearing a carved pumpkin.
