The Amazon Princess and the Pea

Wonder Woman recognizes that the Beastiamorphs overrunning the island of Valdonia are creations of her old enemy, Circe, so she sets out to deal with the threat; but she finds that the petulant king wants Superman, Circe has disguised herself, and the only clue is a strange, pea-sized stone hidden under a tower of mattresses on Wonder Woman's bed--and she has to untangle Circe's spell, defeat the sorceress, and prove to the king that she is a real hero.
