I open my eyes and I see horses, many horses. Im confused. i stand up and I feel that Im very heavy. I supose that Im in a barn, but why? I walk through the wood door and It is a sunny day but I see everething more tall. Now Im scared, Inwalk to the little river near the barn and I see my reflection, Im a horse! I snore and I start to jump like a crazy horse and an old man tries to calm me down and I stop. Besides the old man there are 5 knights with shiny armours. A knigth points at me and the man catches me and he drives me to the knight, that knight is confused just like me. The name of the knight  is Sir Robberts and he drives me to another barn but know we are alone, without horses. He starts talk to me and he tells me that he travelled to this year through a time machine. He also tells me that today he has a joust with the best knight and he doesn't know how to fight. He tells me that his really name was Steve. I jump of happiness when I find my friend Steve, he saw me very strange but when I discovered that I can talk I say to Steve that Im Max.
