In the magical realm of Shiro, life for the young Mushling Cale, is anything but easy. He's stuck with rowdy housemates, falling behind at school, and barely scraping by as a part-time busboy. His only joys are his beloved pet Truffles and a strange blue button he wears for protection. Cale just wants to be left alone with Truffles, but when alien invaders steal the magical Stone that protects his world, Cale is unwittingly thrust into a perilous quest to find it. Armed only with a mysterious scroll, separated from Truffles and stripped of his talisman button, he and two loyal friends are pulled into an unknown, dark and dangerous world. Lost and vulnerable, Cale must now outwit shadowy creatures, survive impossible challenges, unlock ancient secrets, and find the courage to become the hero Shiro needs... before it's too late!
