Golden Gooby is deaf in real life.
Probably the most likely reason why she doesn't speak in any of the videos, even in the one where her sister, Sacred Snewpee, makes her VO debut.- Incorrect. She is not mute IRL, but her character is. She does talk on her art streams, just not very much.
Hellbent is Dolan and Zaraganba's adopted brother.
Could explain why Ramona is sometimes cast as their sister and sometimes as Hellbent's.
