Sea Fairies

The Sea Fairies are Mermaids that live in the oceans. Their Queen is Aquareine. Trot and Cap'n Bill meet the Sea Fairies in a seacave named Giant's Cave and are taken by them on an adventure under the sea. In a later adventure, recounted in The Scarecrow of Oz, the Sea Fairies save Trot and Cap'n Bill from a giant Whirlpool by carrying them to an undersea cave which leads them into the Land of Oz.
