I don’t know how much you need to write but say something on the lines of “I went bucking with my prarents and I missed a step and fell down the side of a hill and stumbled into a cave. I went inside the cave to see if there was a way I can go through to the other side and saw this creature sleeping in a nest. It looked like a miniature dragon. Once it woke up it was friendly and whenever I thought of something I wanted in my mind it would transform into that object”
