Mrs. Yoop

The giantess wife of Mr. Yoop. She is a very pleasant giant in appearance, clad in silver robes that have gay floral designs embroidered on them. But she is a Yookoohoo, and is only concerned with her own desires and interests, which make her a threat to other people. She captures Polychrome and turns her into a Canary to keep her company. When the Tin Woodman, Scarecrow, and Woot enter her castle she turns them into a Tin Owl, a stuffed Brown Bear, and a Green Monkey. Thanks to Woot they escape by capturing Mrs. Yoop's Magic Apron. Ozma subsequently returns them to their true forms and changes Mrs. Yoop into a green monkey.
