Fresh off the excitement of her camping trip, Yotsuba initiates a very
productive session of sandbox play in which she instructs Fuuka how to
properly run a bakery. But even more exciting is a visit from Grandma!
Yotsuba learns how to value and enjoy cleaning, how not to be rude when
hoping for souvenirs, and most important, how to cope when Grandma
leaves. But don't worry, she'll be back someday!
