I like the Headcanon that Branch's color act like a mood ring for one of the dumbest reasons
I've adopted the Headcanon of Branch's color being a sort of mood ring, where his skin gets brighter the happier he is, for the sole excuse of wanting Brozone to obsess over it
To explain, I like to think that, After TBT, Brozone sorta suck up to Branch a little, and when they find out about the mood ring thing, They all go into Overdrive Mode, treating Branch like a Wagyu Cow.
To the point where they have a "Branch List" about his Likes and Dislikes. The best way to describe this is "The Badness Chart" from Lilo and Stitch, So it's like...
John Dory: Okay Bros, Branch is right here . . . . (Gestures over to a picture of Branch with Grayish-blue skin) Where WE want him is here . . . (Gestures over to picture with Baby Blue), what are some ideas?
Clay: Well looking at list, he likes Safety, Cooking, . . . Someone named "Gary", but hates large crowds, . . . . A sentient cloud wearing socks and no shoes, and (Points to Creek on a picture) this guy
Bruce: Who's that guy again?
Clay: No clue, I think his name's Creek. He mostly keeps away from where Branch is, but I have seen them give each other some "Death Stares"
Floyd: . . . I know this is really extreme, but I know a really good Hitman that owes me so we could probably—
Branch: Uhhhh, what are you guys doing?
John Dory: OH SH*— I mean . . . Hey Branch, you wanna go get donuts, I'm feeling Donuts, but only if YOU'RE up for donuts
Branch: Oh yeah, I was gonna go get some with Poppy—
John Dory: GREAT, count me in, go get ready
Branch: . . . Okay, Just let me go ask Poppy
John Dory: Okay, Clay and Bruce, burn everything, only keep what we need, and Floyd . . .
Floyd: . . . I'll give him a call
Look this made more sense in my head, and I'm sleep-deprived, but hope you like what my semi functional mind could produce
