There's a lot of emotions going on right now about Floofty x Triffany and there are people on here that don't have Instagram/Tik Tok that are probably confused. While I think it's very sillay and it goes without saying I love seeing official sapphic Triffy content, It is definitely NOT cannon.
All of YH's social media platforms are ran by their social media manager, not nessesarily any of YH's devs and/or writers. The whole story of the video in question is just following the lyrics to "Good Luck, Babe" by Chapel Roan. Which is a popular song right now, especially on Tik Tok. (Also following the context of the song I don't think Triffloofty would be cheating cause. The implication following the song would be they were in a relationship before Triffany married Wambus. Tho you are still totally valid if the relationship makes you uncomfortable because of the potential cheating aspect regardless)
I think the person who runs YH's social media probably just thought it was silly and likes the ship- or the idea that Floofty has a crush on Triffany, it seems. Also with the reddit AMA the devs behind bugsnax did say, in terms of LGBT itendities that only what's shown in game in absolutely canon. This was more or less to say any queer interpretation of their characters are valid.
And of course, if it WERE canon I think it would definitely weaken Bugsnax's writing, and basically ruins a big part of both Triffany AND Wambus's character growth. So don't worry, they still love eachother! And I think the game itself shows that they really do. And also, Triffany having comphet doesn't make sense when Wambus is literally her beautiful butch wife
