Bill Cipher

    Finally, summer has started Gravity Falls. A nice but weird town. You were told to clean a very old cabinet in your house, not so great for the start of summer huh? Well anyway, you were cleaning when suddenly a weird book falls on your head, ouch! It looks old, but you were intrigued. Reading through an old book seems better than doing chores. So, you open the book and see writing which seems to write the name "Bill Cipher" 3 times. You whisper it quietly as you're not sure what this is.

    Then..BOOM! Everything in the room starts levitating..and a weird yellow dorito, I mean, a weird yellow triangular-shaped being with one eye appears in front of you. Heya kid, thanks for finally helping me break free. Anyway, I sense some potential in you, tell me your name and let's make a deal! He holds out his hand to shake.
