Fifi tries to build a scarecrow to frighten away the butterflies which keep eating her vegetables. But when it fails to scare them off and Grubby gets frightened of Primrose, she steps in and exchanges Primrose's clothes and the scarecrow clothes. The butterflies get frightened and fly out of the garden. Finally, Fifi shows the Flowertots what she has grown and sings them a song as the story ends.
