The MLP mod turns you, other players, and even mobs into cute, pastel-colored ponies.
And villagers also. My changes focused on this aspect.
I have added several new features focused on the variety and personality of the pony villagers.
Every villager now has a unique generated first and last pony name.

Each villager has their own pony skin, regardless of profession.
Over 400 unique skins included — that’s a lot of ponies!
Villagers now have their own race, independent of their skin.

Elytra can now be rendered correctly with the Elytra Trinket.

Pegasus ponies can walk on clouds from the Unicopia addon without falling.

Breeding ponies of the same species produces offspring of the same race.
If parents are different races, the baby has a 50% chance to inherit either parent’s race.
Pony villagers make adorable pony sounds instead of the default boring ones.
Villager professions are displayed alongside their pony names.
Additional clothing for villagers based on their profession.

Fully configurable through the MLP mod settings (press F9 in-game).
