The ZOOMers play "ZOOMer Flip." Estuardo and Matt experiment with yeast in ZOOMsci. Then, Aline and Caroline use yeast to bake up a loaf of "Bread in a Bag." Grown-ups just can't understand Caroline, the baby who can talk-in Ubbi Dubbi! And in the ZOOMplayhouse, when Aline can't sleep, it's Caroline and Rachel to the rescue.
