Gravity Falls

On November 20, 2015, Alex Hirsch announced via his Tumblr that Gravity Falls would be ending with its second season in the form of the hour-long series finale. In the Tumblr post, Hirsch stated that the show wasn't being canceled, it was being finished and that this was 100% his choice not Disney's. Hirsch said he had planned out a story for Gravity Falls from the beginning and that it was simply reaching its natural conclusion. Hirsch never wanted Gravity Falls to continue on with multiple seasons, just because it was popular, until it jumped the shark or faded into obscurity like numerous other children's cartoon shows. Additionally, Hirsch also said that by ending the show after its second season, it just means that this chapter of the story is done and for now, he's done telling the story. Hirsch has been keen to remind fans that he has left the door open for future Gravity Falls stories and that he would be willing to return to the Gravity Falls world someday in the future.

Throughout the series, the Dinosaur Skull's (Probably a Tyrannosaurus skull) Fenestra (Hole in front of the eye hole) keeps changing shape along with its location on the skull.
