Use goat horns to call all tamed mobs, villagers, and iron golems to you

Tamed mobs: 
The goat horn would be able to call all tamed mobs toward you. Mobs like cats and dogs would instantly teleport to you, regardless of if they're sitting, and regardless of how far away they are from you. Tamed mobs that can't teleport like horses would instead walk toward you as long as you are in a 30 block radius within them.

Villagers:

If you have the hero of the village status effect, all villagers would walk toward you, making trading easier. 

Iron Golems:

If you have built any iron golems yourself, you can call them toward you as long as you are within a 30 block radius of them, this can be especially useful during battles like raids. If you have the hero of the village status effect, all iron golems of that village would walk toward you as well.
