I made this because I noticed there were not any unicorn add-ons on MCPEDL and thought you might like it so here we are. :)
This Addon has a sword that gives buffs and unicorns that replaces the mule. There is another item called the Unicorn Horn Shard too which is used to craft the sword.

I changed the Unicorn's horn to a better model because before it wasn't quite central.
My daughter loves it! She was disappointed when there weren't any before. Thank you
