Spunky Gracie brings a tiny seed to Grandma, but won't tell her what kind it is. As the seed sprouts into a giant plant, Gracie teases Grandma that maybe it's a balloon tree... or a monster tree! Grandma happily imagines a cow tree that will give her an endless supply of milk for her coffee. The answer is more down-to-earth--something the pair gets to savor together--something big and round and red and wonderful!
