Just as it says, I'm looking to see how to fit Lord of the Rings into a pony world.

So perhaps....
Hobbits should be Earth ponies.
Humans are Zebras.
Elves, I like Flutter ponies for this.
Orcs should be Diamond Dogs.
Wizards are Unicorns.

I need help for the rest.
Also I'm thinking all possessors of Rings, should be granted Alicorn status regardless of original race.

To aid you with this head-canon of yours, Timber Wolves are Ents, Donkeys are Dwarves, Minotaurs are Trolls, and all the Wraiths are Changelings!

My own head-canon for this (based on books, not films), however, is:

Human-types:
Shetland Ponies: Hobbits
Ponies: Men
Mearas (a horse breed in Middle Earth): Elves
Tarpans: Orcs
Draft Horses: Olog-Hai
Shires: Giants
What appear to be elderly ponies, but are so much more...: Istari (Wizards)
Ghostly equines: Wraiths

Non-human types:
Donkeys: Dwarves
Timber Dogs (creature I made up): Ents
Timber Wolves: Huorns
Minotaurs: Trolls
Dragons: Dragons (duh!)

Anyone else have a unique head-canon about this?
