This is a seed which is really great if you want a horse and diamond horse armor quickly after spawning. You might not be able to get a horse instantly but since they spawn naturally in savannah biomes it is clearly possible to find one with a little bit of searching.
There is one blacksmith in the village and inside you will find a chest which contains the following items.
- 1 Iron Pickaxe
- 1 Diamond Horse Armords0.16.2 Seeds0.17.0
- 1 Iron Helmet
I realize it isn’t a perfect seed seeing as you will need a saddle to control the horse. But it definitely sets you on the right path if it’s a horse which you want to get!
