When a new spot opens up in a prestigious Choir of Space Angels, Bubbsriel (Carly Monardo) is summoned from the CSS Cavalier to Space Heaven to see if she's up to the task. She'll have to give it her all, because overseeing her trials are none other than Holy Attorney General Zacchaeus Zebulon (Christopher Hastings). Luckily, Bubbs will have help from a familiar face- gasp! Is that- Froglevel?!? (Ali Fisher) (it is).
