Green Flag See if you can decode the secret message at the end! It is the numbers-It is the Number Cipher (Note:I had to look up this cipher because I couldn't remember what all the letters were!) Also, listen closely to the whisper when it gets to the end of the theme. I set it to play in reverse to reveal the way to decode the ciphers of Gravity Falls S1 Episodes 1-7!
Thanks Uncle Grandpa and Gravity Falls
