Yeah, don't do that. 4/20 is only 4 days away, we can all wait.
Also it is worth remembering that the expanded Zen friendgroup (Arielle, heavenlyfather, EvilToaster etc) refer to it as being "stolen" or "kidnapped" when they join an impromptu Zen collab. Or it could easily be a completely "new" vtuber, hired from one of the many corpo graduations we've seen these last few months.
I'm not saying it
couldn't be Snuffy - and 2 years ago I would've said it was a sure thing - but Snuffy seems more chummy with the ex-Vinesauce vtubers (Limealicious), 3am (Coqui + Meat) and Dokibird these days than anyone in current VShojo. Would be pretty left field if she joined.
