It's quite easy, you just find the unicorn again, break it and hitch it
You have to find it. It usually says theirs a mythical creature around you.
No, you can only find it once I'm afraid
Nowhere in reality, they are mythical(imaginary) creatures. ( the above is a LIE!! i have a unicorn in my backyard)
marco polo found a unicorn. it is likely that he found a rhino
A pig unicorn and water lizards. But it was just a rhino and alligators
You need to go to Game Marketplace. Find Red Dead Redemption. Then there should be a DLC list.
You find them all around the map
