Call your happy ghast with a goat horn whenever you need it

The happy ghast can be anywhere, it always works to teleport it to you, even in unloaded chunks

How it works

Give the happy ghast any name (it can't have special characters like # or ')

Hold your goat horn in your hand

Sneak and look at the happy ghast

Your goat horn will get enchanted and get the name of your happy ghast

Whenever you use the horn, it will teleport to you

--> Anyone with the horn can call the happy ghast

--> To unbind/reset the horn, sneak + look directly up

Leashed entities also teleport with the happy ghast (make sure to first attach the leash to the happy ghast, and then to the entity)

Config

/trigger call_your_happy_ghast.config

You can configure 2 things:

If players can sit on the happy ghasts if you teleport it

If players should automatically mount the happy ghast after calling it
