Features twenty-six vignettes, one for each letter of the alphabet, starring Mary Poppins and other characters from the Mary Poppins novels.

Who else but Mary Poppins can lead the Banks children on such extraordinary adventures? Together they all meet the Goosegirl and the Swineherd, argue with talking cats on a distant planet, make the acquaintance of the folks who live under dandelions, and celebrate a birthday by dancing with their own shadows. And that's just for starters!
