PB and Jeli are best bear friends. They play ball together every single day, until the day Jeli gets sick. After the doctor prescribes medication, Jeli begins to feel better but to her surprise, the medication turns her fur purple! With the help of her colorful and caring friends, Jeli learns that there is more to who you are than what shows on the outside. And that maybe being positively purple is positively perfect! This book explores the power of empathy and friendship in building a child's self-esteem. Self-acceptance is a strong theme running through the story, with a clear message that change in your appearance does not change how your friends feel about you.
