Soooo the first theory, at the Friend Medley scene, Branch is comforting Poppy, and friend-zoning her at the same time...

Maybeeee

he said "you're my best friend" so he won't be friend-zoned after he says that he really loves her at the ending part... 😕

And also, maybe he said "friends" on the other lines of the song because, like what I've said,
   so that he won't be friend-zoned in case Poppy doesn't like him back... 🤔

Buuuut!

It turns out that Poppy likes him as well because of how she acts in the Friend Medley scene like duhh, she looks pissed off 😝😝😝💕

And she said "I love you" back for Branch on the True Colors scene boiii

(lel Friend Medley and True Colors are almost the same and the only difference is that True Colors is much more dramatic and Friend Medley is a FRIEND-ZONER)

Another theory, I think it's the Trolls' tradition that they "boop" each other's noses when there's something between two Trolls. 💖

Also, (wait, how many times I mentioned this?) this PROVES BROPPY

I KNOW, I KNOW, I'M JUST REPEATING THEM XDDDD

Sorreh I luv Broppy so much :3

One information about the start of Trolls Holiday (I read the first part because of the sample in Google Play Books :3), Branch is... Okay I'll just screenshot it. XDDD (ish too adorable!)

(skip this part to the end if you don't want to be spoiled 😁)

(I only screenshotted the Scrapbook part so it's not all of the sample)

Branchie ish trying to tell a joke at Poppy, but she *sobs* didn't laugh 😭

Naaah it's not funny tho... BUT CUTENESS OVERLOAD!!

Btw, I almost memorize Friend Medley XDDDD

(I can't understand the lines of the Forest Creatures so I can't memorize all 😕)

And I also know three lines of Double-Down Speed Round XD (one is the thing with a cuss 😂)
