MiFaSo was the orange-garbed member of Cornelio's DoReMi Elves. The conductor had captured each of them as part of his attempts to create a DoReMi orchestra. When the Prince inadvertently released the DoRemi Elves, MiFaSo was one of those who escaped.
MiFaSo would eventually be rediscovered in the woods east of Doraat and would be recaptured by Cornelio.
