Gravity Falls Theories

Hey guys! You know that show gravity falls? Well heres my theory on the unknown #1 book:
At the end of the theme song, A page shows up with the illuminiti and all that stuff but there are some things that describe the characters like in the picture below

 

Glasses: Sherrif Blubs because hes the only one who wears sunglasses (Stan has normal glasses)

Stitched Heart: Robbie because he has one on his hoodie

Shooting Star: Mable because thats on one of her stylish sweaters

Lama: Deputy Derland becuase sometimes he acts crazy...LIKE A LAMA!!

Hand: Manly Dan because his main scource of strongness are his hands (Have you seen the size of those things???)

 

Star: Gideon becuase thats his official sidekicks symbol

Tree: Dippr because of his hat and last name

Fez Hat Symbol: Stan becuase that symbol is on his fez hat

Ice: Wendy because shes as "cool as ice"

Question Mark: Soos because its on his shirt

 

 

So anywyas, I was thinking that might be a page from from the #1 book.And if thats true, it means that the #1 book is about the people of Gravity Falls just like how the other 2 are about the magic and cryptids/paranormal activity of Gravity Falls!

My other theory is that stan might be SlenderMan in disguise. Here is my proof: In the picture of stan in Dippers Daydream from the episode :The Legend of the Gobblewonker", He has a purple tattoo. Normal, right? WRONG!!! If you look closely at it, it shows Operator Symbols (Symbols that are said to be made by SlenderMan) Also, the cymbol on Stans fez hat is a real symbol but its kinda funny how it looks like a backward "C". Well the lettter "C" somertimes makes an "S" sound..."S" as in SlenderMan!

Do agree with my theories? Comment below and tell me!
