All this made the fish very unhappy.

    “I am 12 with this rain but my friends—trees and animals are quite unhappy. Oh little fairy! Please 13 the rain. I will go back to my pond. I will be more pleased when trees, animals and birds are happy,” pleaded the fish. The water began to 14 , and the animals were very glad and ran off, and the fish 15 to the pond and she was happier than ever before.
