From L.Frank Baum's book "Glinda the Good" the last of 14 Oz books. The Skeezers lived on the Magic Isle of Skeezers which is a glass domed city that can be fully submerged when necasary. They were at war with the flatheads and entrapped Princess Dorothy and Princess Ozma of OZ.
"The Skeezers are led by a domineering young queen, who has a dark secret"
(possibly the origin of the modern term????)
