Mumu stumbles upon a group of sheep grazing in the park where he usually plays with his friends Milo, Rita, Talalo, Alfred, and Olga. He can’t help but notice how their pristine, snowy appearance contrasts with his friends, who are like a patchwork of various fabrics, covered in colorful spots as they frolic in the field and splash in puddles. Mumu feels a mix of embarrassment and envy towards the sheep’s gleaming coats. Upon realizing that these sheep are actually flawless stars destined for a grand performance, Mumu becomes so captivated that he decides he must transform himself to also become a glamorous star. As a unique cow, he realizes he can’t afford to waste time with the wrong crowd of friends.
