Gravity Falls is a Disney animated series from 2012. It is a mystery-based series where we get to follow Dipper and Mabel on their summer vacation at Grunkel Stan's.
The title sequence is based on the journal that Dipper finds at the very beginning of the series. The book shows an overview of supernatural beings from Gravity Falls. The title sequence introduces the characters in the same way as with the creatures.
I combined fast phase music and playful images from the book to bring out the chaotic and mysterious atmosphere that the series has.
