Harold is turning seven years old. He’s never had a real birthday party. That’s because his parents are too grumpy.

But this year they feel bad for Harold. “We’ll call up Mr. Ponzio,” says Harold’s mother. So they do, and Mr. Ponzio agrees to help, “The party will be absolutely extraordinary, Mrs. Snipperpot.” When everyone arrives at the Snipperpots', everyone—especially Harold—is absolutely flabbergasted. It truly is a party like no other.
