Papá's Magical Water-Jug Clock

Today, little Jesús has a big job to do. He's helping Papá at work, and he's in charge of the water jug, which is also a magical clock! When it's empty, Papá explains, the workday is done. But what about all these thirsty animals? Soon, the water is gone, but the day is not over yet. Will Jesús be fired? Or is the jug not really magical after all.
