So you've got your desktop MetMachine. Where next in your mini-Ring?
Sadly it seems just as tough to cast a desktop Ring cycle as a real one.
In fact the only candidate I could find was 3" pig Olivia. Olivia is not just a professional opera singer, she's also poseable, an asset to any budding director. And she has "small parts", which should please the General Manager.
I'm not quite sure of Olivia's Fach, but Amazon reviewer 'Mom in CT' points out "Her dress doesn't stay on" which indicates she may be a soprano. On the other hand, her "painted on underwear" suggests mezzo tendencies. Let's just put her down for Brünnhilde.
