Dipper and Mabel's Guide To Mystery and Non-Stop Fun: Secret Codes
(Sorry this took so long, BTW.) Here are the codes I have found in Dipper and Mabel’s Guide To Mystery and Non-Stop Fun. The first group of codes will be Bill’s. Then I’ll move on to Dipper’s codes. All of the codes will be bold.(The page numbers will be in parenthesis.)
“Dipper wrote a theme song for himself and sings it in the shower.” (20-21)
“After nightmares, Mabel meows herself back to sleep.”(30-31)
“Soos keeps candy in his belly button for emergencies.”(52-53)
“Stan was a baby model.” (69)
“The mayor of Gravity Falls is not long for this world.” (76-77)
“Wendy wishes she lived in Portland.” (80-81)
“The end of the world is closer than the end of the Summer.”(88-89)
“Something strange is buried under Gravity Falls.” (92-93)
“Time Baby is worried about Bill.” (94-95) (I talked a bit more about this one here.)
“Bud Gleeful wants to run for mayor.”(96-97)
“McGucket has seen terrible things.”(106-107)
“Grenda will marry Rich.”(108-109)
“That burnt tree by Soos’s house is odd.” (116-117)
“Soos writes fan fics about Stan.”(118-119)
“The Gnomes have a clear view of Northwest Manor.”(124-125)
“Dipper and Mabel’s father worked in computers.” (132-133)
“Robbie secretly draws anime.” (142-143)
“The invisible wizard keeps untying Dipper’s shoes.” (144-145)
“The government can be forgetful.” (148)
“Growing up is optional.” (150)
“Robbie is a jerk.” (123)
“This is way more fun than going outside.” Writing codes, he means. (124)
“To get back at Mabel,Candy, and Grenda for their tickle attack, I’m going to put peanut butter in their socks!“ (131)
The next one is on Dipper’s Certificate of Mystery (151):
It’s missing it in this photo, but there’s a code surrounding it:
As you can hardly see, there some black letters mixed in with the blue ones. Those make up this: “DISNEYXD.COM/ARENTYOUCLEVER” which shows this:
[That code says,”You’re not as dumb as you seem…I’ve got some secrets if you know where to look. The people of this town are an open book…”]
The blue-lettered code on the certificate says: “By signing this official document, you are hereby agreeing to dedicate your life, your afterlife, and any potential clone-lives to the discovery, uncovery (Is that a word?), and exploration of the paranormal, the alter-average, and the extra-usual. When friends ask you to stop being paranoid, you will scoff. When they say that you’ve been acting really weird since you read that book and they don’t even recognize you anymore, that means they’re jealous/you are like me now. We are part of a higher calling. We will meet one day and on that glorious day we will show the small-minded doubters we were right all along, and are also really cool, and they should have been nicer to us. Okay that’s about it. This sort of sounds like a supervillain manifesto in retrospect. But you get the gist.”
Bonus! Gideon code in his letter to Mabel (Page 87):
The letters on the side read, “Help me escape or be destroyed.”
That’s about it. Remember, REALITYISANILLUSIONTHEUNIVERSEISAHOLOGRAMBUYGOLDBYYYYYE!
