Cayke is a Yip known for the delicious cookies she bakes in her diamond-studded gold dishpan. Unknown to her, it is a Magic Dishpan and can carry its occupants to anywhere they may desire to go. Ugu uses Cayke's dishpan to kidnap Princess Ozma and steal all the magic in the Land of Oz. Distraught, she turns to the Frogman to help her retrieve the dishpan, taking them on a journey throughout Winkie Country where they eventually encounter Dorothy's search party for the missing Princess Ozma and join forces. After a confrontation with Ugu, he is transformed into a dove and uses the dishpan to escape, but later the Scarecrow and Tin Woodman find the dishpan in Munchkin Country and it is returned to Cayke in the Emerald City.
