What happens when you combine Greek mythology with D.W.'s imagination? When Grandma Thora shows D.W. how to be an author of great stories wi thout even knowing how to write, D.W. tells a fantastic tale (with a l ittle help from Homer) that impresses even Arthur. In the second story , getting two Polly Locket dolls almost ruins Prunella's birthday part y. That, and Francine's bad mood--why, she wouldn't even sing the happ y birthday song! Wait...is there a connection? The Ghost of Presents P ast appears to Prunella and shows her a thing or two about friendship and gratitude.
