Diablo

Would YOU buy a horse called Diablo? Seriously?
Kim is the world's best parent pesterer. So when she pesters for a pony, she gets a pony. What she doesn't know is that she's just adopted an Evil Genius with only two things on his mind - hay, and World Domination. Having a horrible beast of a brother doesn't help. Soon Kim realises the awful truth. There's only room for one Boss in the paddock. Who is it going to be?
