Here is the second request from   RyanBrony765

A few well know race horses came across the cities local police horse. They all made fun of him for wearing something so childish, so our poofy friend here challenge them to a race to prove that his diaper gives him a better speed then any of them. Of course the others accept and soon all race each other. Somehow they all lose to the poofy horse and were completely shocked. The poofy horse said that his diaper is magical and to prove it, he made himself start to grow bigger and bigger~ All proud in his size, they eventually said sorry to him, goes to show don't judge folks for what they wear or do~ X3
