We should have minecraft horses. We've got all the pigs, cows, sheeps, even chickens.
Now... hmm... What farm animal did we leave out that is so obvious? HORSES.
We could get around easier other then walking, we already have saddles for those pigs... but its sorta a waste you can't control them.. Pig-riding... hmh...
Well what about something that's really meant for saddles something that man-kind has known for centuries! Horses. Thats right bois. Horses.
As well as the ocelot and the average wolf, Your going to have to tame them into cats and dogs for a companion! and yes as well for horses to. grass? eh. why not? Now heres the hard part on how to tame it... I guess what ever action the horse does.. like the ocelot sneaks you right click a fish on it.. You would right click the horse with grass when ever the horse does and action minecraft designs it to do you'd right click it. Not to hard after all i guess.
You could find them in the wild randomly as well as other mobs like chickens and what not. Black, white, brown colors for them? Why not. Common: brown Uncommon: white Rare: Black
Just putting uncommons rares and commons out there for ideas... like the sheep you mostly see white ones.
So i guess when you spawn one in creative mode it would be brown like the white sheep you spawn.
But i guess you could dye the sheep as well.
So You could say ive stated everything possible about horses for minecraft. I joined minecraft with the highest version, 1.2.5 so I dont know much about the earlier versions.
