In defense of the weird bite booby model, the concept's really rad and I think the execution doesn't miss either. A horrifying man eating monster hiding behind the guise of a beautiful woman. You got a little to close and whoops, you're dinner. I'd like to think no one is jerking it to the monster forms (yeah, I know, naive) but it still does it's job of being a horrifying presentation.
Must've been hell to rig though. You know, I wonder when would the vtuber in question use those toggles? I feel that it would become a novelty roleplay deal that gets old quick. After that you just have several expensive toggles that you barely use. For the artist and rigger, it's a great addition to their portfolios, but for the streamer in question... what next?
