A young farm boy who loves his animals and flower garden receives a blue horn whose music enchants the garden fairies; a hidden pansy fairy whisks him out at moonrise to play while the flower fairies dance in the meadow. Fairy dust later makes him fall asleep beneath a haystack so he misses morning chores until his father finds him and he returns home to recount the nocturnal adventure. The gentle tale emphasizes imagination, the magic of the natural world at night, and the playful consequences of wandering after bedtime.
