Is this human pony failing...?!

Mistress Zora pushes the slave on all fours and wants to see if he makes a good little horse. But what she sees looks more like a lame, stupid donkey, an old nag for the charity yard - or a pony for the sausage factory! So she gets on her human pony and rides it around to give it one last chance.... can the slave convince Mistress Zora of his abilities as a pony?
