Homing Donkeys for inventory load out in the wild

So when out and about you get the too much stuff in your bag thing. Well friend have I got an idea. Homing donkey; they’re like homing pigeon, but its a donkey. And what is so special about this beast? Well it can be called on occasionally; perhaps a cool down to keep it real because it is not a magic donkey. It just has a good sense of direction. You can offload stuff to it and they trek back to your house or Sanctuary, hence the coo ldown.

Of course it gets all the fancy do-dads like naming it, customizing its look (think urban sombrero), storage enchantments, et al.
