I open my eyes and I see horses, many horses. I'm confused. i stand up and I feel very heavy. I supose that I'm in a farm, but why? I walk through the wooden door and It is a sunny day but I see everything shorter. Now I'm scared, I'm walking to the little river near the farm and I see my reflection, I'm a horse! I start to jump like a crazy horse and an old man tries to calm me down so I stop. Besides the old man there are 5 knights with shinny armours. A knigth points at me and the man catches me and drives me to the knight, that knight is confused just like me. The name of the man  is Sir Robberts and drives me to another farm but I know we are alone, without horses. He starts talking 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 I'm Max. After that I woke up and I felt very tired.
