Heh, my kid loves this show a little too much.
I caught him putting tiny Bill Cipher triangles with eyes on his schoolwork. 
My youngest daughter enjoys making Bill Ciphers out of Perler beads, complete with flaming hands. My older daughter found a pattern for Celestebellebethabelle (the world’s most irritating unicorn) that she wants to put together.
At the end, all I could think of is, “What happened to the Time Baby?”
My daughter is head over heels that she resembles Mable and often dresses like her (down to the tortilla chip earrings we made out of polymer clay).
Grunkle Stan, however, is my favorite.
Gravity Falls has been the white noise in my house for weeks. My son loves it & yes - he watches way too much television. He says it might not be on the map, but it’s a place you can go visit & it’s definitely in Oregon…I haven’t checked his facts yet. But if it is, we will stop by on one of our travels.
His molecules will regenerate in a thousand years. At least, that is what the cryptogram that appears during the credits of “Weirdmageddon Part 1” says.
One person who I expected to amount to more was that bald time travelling dude. He survives Time Baby and the troops being wiped out, but he vanishes and doesn’t reappear.
Keep her away from that sugar dip stuff. 
My name is Stanley. Guess what my grand - nephews now call me?
Sigh.
That’s awesome.
