Mama, Why?

"When the moon sails high in the arctic sky, Polar Cub asks, "Mama, why?" A polar bear cub asks his mother a multitude of "why" questions before he goes to sleep: Why is there a moon up in the sky?

Why do we dream? Why are there stars in the sky? And why can't we see the stars during the day? Finally, once his Mama has explained everything to him, Mama ushers her little one off to sleep, explaining that she will sleep too, so she can dream about her dearest cub.
