I once rode a zebra, my aunt owned a horse rehab for horses who have been mistreated, and every so often she would get either a donkey or a mule..
One day she got a zebra in and I trained it, helped it regain its strength :)
I rode it a couple times and it was just like a little pony
Have you ever ridden a mule? If so, it felt like that except with a shorter stride. :)
