Wanderer

Wanderers are inhabitants of the outer End Islands. They will simply glide around End's void sky aimlessly, ramming into Chorus plants on accident.

Spawning
Wanderers can spawn out of an Enderman in the End dimension with a range of 1 through 35 (you can learn more about the spawning system in "More Mobs" here). However, they cannot spawn in the main End Island, nor can they spawn in an End City. Wanderers also require a big area to spawn (3x3x3). You can learn more about how Endermen spawn here.

You can also summon a Wanderer using this command: /function imm:summon/imm/wanderer. You can obtain a Wanderer Spawn Frame with this command: /function imm:spawn_frame/imm/wanderer. Make sure to replace the 'imm' portion with whatever version you're playing on if your version is older than Snapshot 3C (example: Snapshot 2A = imm2a).

General
Wanderers are passive mobs that fly around the End sky. They don't panic while being attacked and just continue aimlessly wandering.

Breaking Chorus plants
If Wanderers come in contact with Chorus plant stems or Chorus Fruits, they will break them.

Teleporting
If the Wanderer is close to touching ground it will teleport itself upwards avoiding contact with any solid surface.
