It's the last week of their summer holiday and April, May and June are bored. So bored that they are even starting to look forward to the new school year! But all that changes when Pappy, their adored and wacky grandpa comes to stay.Pappy and the girls decide to bake a delicious challah for their Shabbos dinner, but they get way more excitement (and dough) than they had bargained for when the challah dough just keeps on growing and growing...and growing!Adventures with Pappy are always fun, but this time, have they gone too far? How will the girls put an end to the unstoppable rise of the challah dough? And can they count on their creativity and kindness to save the day?
