In the charming tale of the polar cubs, Mushka and Mishka, two young polar bear siblings, embark on a series of escapades in the icy realm of the North Pole. While Mushka possesses a contemplative nature, Mishka exudes boldness and a thirst for adventure. During their solo expeditions, Mishka strikes up an unlikely friendship with Aura, a mischievous seal known for his playful pranks, while Mushka inadvertently causes chaos in the bird community by accidentally destroying swan eggs. Their father, Scholar Mu, voiced by Joseph Campanella, serves as the esteemed leader of the Great Northern animal kingdom and oversees the annual Summer Festival. However, when Scholar Mu falls victim to a human-caused injury, it falls upon the young cubs to step into their father's shoes, shoulder his duties, and protect their fellow animals from the looming threat of hunters.
