Coco Banjo loves her life. She sleeps in a tiger onesie, wears her mom s diamonds just because she can, and has dolphins and penguins for friends. Today Coco s planning a Yay Day of fun on her secret island home in the middle of Sydney Harbour. But wait . . . what s that Secret Signal? Oh no, Narianna (known as N) is being bullied Coco sets off for school to rescue her. But when cranky school principal Miss Trample sees Coco s school uniform (customized, thank you very much), Coco might be in even more trouble than her best friend. How will she get out of this one?"
