Gravity Falls: Back to the Falls

My name is Anna. I had just moved from the bustling city of San Francisco all the way up to a small town named Gravity Falls just after my fourteenth birthday. My parents wanted to leave the bustle of the city and live a more peaceful life, where the air didn't constantly smell like urine and smoke. While I missed the city, the country was starting to grow on me. The scenery was nice, and so were the people, (although they were a bit strange). But after a while...I noticed some strange things going on. Once on a walk in the woods I felt like I was being watched and when I turned around I caught a glimpse of some strange shadowy figure, another time I thought I caught a glimpse of some tall bull but when I looked again I saw nothing. Not too mention my new job at the Mystery Shack. While I love it and my boss is the friendliest guy ever, I always felt like...something big happened. Especially when I found a giant tooth and when I tried to ask him all he said was 'oh, never mind that!' In fact, everyone in town said that. What was this town hiding? Why all the secrets? And where is my moisturizer?
