Shorts

A series of Gravity Falls shorts were produced to air between Seasons 1 and 2, riding the momentum of the series' success. The series of shorts kicked off on October 14, 2013, with new shorts premiering everyday that week at 7:25pm EST.

The events of the shorts take place before "Gideon Rises," as Dipper still has 3|Book 3.

Hidden page
At the end of every short there is a section of a page that is briefly flashed, revealing information like symbols and cryptograms.

Codes in red
There is code used in the red numbers on each page. It can be translated by using the number in front of a right parentheses to indicate the Gravity Falls episode number and the numbers that follow it to indicate the letter number of the episode's decoded credits cryptogram. Brackets indicate the beginning and end of words.

Candy Monster

 * The numbers at the end, [13) 8,9,10] [14,17,22 decodes to "THE DAR."

Stan's Tattoo

 * The numbers at the end, [1)14] [2)5,24 3)3] [5)7,9] decodes to "I WAS SO."

Mailbox

The Hide Behind

 * The numbers at the end, 11)4,12,13] [12)8,9][17,13] decodes to "IED TO ME."

Decoded, the message that is composed of red numbers from all the images that flash at the ending of each short combined is "I WAS SO BLIND. HE LIED TO ME. THE DARKNESS IS NEAR."

Cryptograms

 * In "Candy Monster," the cryptogram says "IURP WKH ILUVW XQWLO WKH ODVW VHDUFK WKH." Once decoded, it reads, "FROM THE FIRST UNTIL THE LAST SEARCH THE."


 * In "Lefty," the cryptogram says "WKHP DOO ZHOFRPH WR JUDYLWB IDOOV." Once decoded, it reads, "THEM ALL WELCOME TO GRAVITY FALLS."


 * In "Tooth," the cryptogram says "FRGHV RI FUHGLWV SDVW RQH PHDQV RQH VR VHDUFK." Once decoded, it reads, "CODES OF CREDITS PAST ONE MEANS ONE SO SEARCH."

If arranged correctly and read left-to-right, the cryptograms read "FROM THE FIRST UNTIL THE LAST SEARCH THE CODES OF CREDITS PAST ONE MEANS ONE SO SEARCH THEM ALL WELCOME TO GRAVITY FALLS."
