Have you seen Gravity Falls? If you have, you know that the cartoon is very amazing! If you have not, you need to go to Hulu or Disney Now and start watching now! There are only 40 episodes of the cartoon, but each episode is written very well and connects to a bigger overall story plot you see at the end of the series.
The folks from Channel Frederator made a video talking about the entire Gravity Falls timeline. If you need a refresher, or need to know what Gravity Falls is all about, this timeline is really well done!
