  • According to Vivziepop, not only was she a fan of Billy & Mandy, she approached Maxwell for voice-work after volunteering on his "Dead Meat" series, and as such initially only recorded for the "Inside of Every Demon is a Rainbow" portion of the pilot. When the pilot received further development, Maxwell was approached again to play the pickpocket incidental among other additional voices in which he was recorded and directed in-studio at one of her workers' recording studio.
