Diva Maria Calloused once sung with her entourage at the Opera Frobozzica. The stage lights for the concert hall were controlled by a miniature Opera built by Dr. Koepp; because of this, as Diva Maria grew so substantial in person, neither she nor her enlarged entourage could fit their fingers into the model, and thus had no choice but to sing a season entirely in the dark.
