My Pet Turtle

First, one day I came out with my brother and his friend to the pool. Then I said, look down to the pool it was a turtle. We picked it up. I asked my dad if we can keep it. My dad said yes, when we first cleaned his cage he bit my brother. We don't know if it is a boy or a girl. His name is Squirt, from the movie "Finding Nimo". We had him for a year.
