Where can I locate the "mutant donkey female" steed?
I do not think there is any kind of means to purposely create this to take place. It is more than likely brought on by the video game perplexing the versions for the steed with the versions for the male or female, and also it does not appear to take place to a details NPC. I assume the only point you can do is maintain playing till it takes place. (If it takes place).
