The Blueberry Pie Elf is a children's courtesy book that was written by Jane Thayer and illustrated by Seymour Fleishman.
Originally released in 1961 by Oliver & Boyd in the UK and William Morrow in the US, the story, written in prose, follows a little elf who is desperately trying to get a family to bake more of the blueberry pie that he loves so much.
One day the family bakes a blueberry pie, which Elmer proceeds to jump into and eats his fill.
Disappointed in the taste, and not realizing that the cherries stained his feet red, Elmer hops out of the pie and walks away.
After the bakers notice Elmer, they take the hint left by his help with the chores and return the favor by baking him a big blueberry pie.
