Vivziepop has said he smells bad in livestreams before I'm pretty sure, or at least it's been well-established in livestreams that he has awful dental hygiene. I wonder if it's still canon, or if it'll ever be confirmed in the show.
My unpopular opinion: I think people take the livestreams too seriously. Even when Viv wasn't joking about something, I think panels and streams shouldn't be held up above the show in how canon they are. Discord RP servers are crazy about treating Viv's public statements/casual tweets as the only way you can portray things! Maybe I need to get off Discord...
