My ultimate adventure

The day had finally came and I was so exited because it was school time . Today at school I looked out of the window and saw a giant tree in the middle of the play ground. Suddenly I noticed that a  little door opened in the tree . Quickly I  ran into in to tree  and felt terrified. Just as I walked in I heard big BANG!! The door shut on me and I suddenly went down into a cage. I felt so scared! One hour later I saw dolphins swimming, I jumped out of the cage to swim with them. They made lovely noises. Two hours later it was time to go and I got back into the giant tree and went back to school.
