I wish we could've gotten some proper Little Sammy being a freak when younger. I just know that that guy would freak all of his classmates out with morbid facts he wasn't even aware most people knew nothing about.
I want to make an AU where Bill was never evil but his personality is still the same outside of that so the Pines twins show up to stay with their Great Uncle Stanford and he introduces them to his husband who's just. A funky little chaotic triangle creature from another dimension. He gives them deer teeth as welcome presents and both he and Ford (who is extremely accustomed to his weirdness after 30 years together) act like that's a Perfectly Normal Thing to Do. Dipper is LOSING it, Mabel is LOVING it (she makes a necklace and earrings out of them)
