Mannie and her Mooooody, Disorderly Day follows Mannie the cow as she navigates a somewhat surprising and chaotic day on the weather pasture with her bipolar disorder. After beginning her morning with an abnormally bright sun and vivacious disposition, Mannie's mood quickly shifts to cloudy thoughts and extreme misery, forcing her to leave school. With parental guidance (from Mootilda and Sir Loin), Mannie attempts to take the S.S.R.I. train to get her sun back, and, when her symptoms worsen, she does not succumb to failure. Instead, Mannie finds her way home with a beautiful rainbow and regulated emotions. This unparalleled tale follows the special case of a cow experiencing strange shifts, yet persevering and maintaining hope in the face of mental distress, despite the fact that events do not begin in her favor. It aims to shine an unprecedented, yet accurate, light on mood disorders and treatment for children, using punny characters and sayings, while also providing an underlying moral about the power of fierce aspirations.
