Whitney Dangerfield, miss imaginative outcast schoolgirl, is trying to conquer her fears and insecurities of growing up. However, her teachers are concerned about her lack of effort, the boy she fancies barely notices her and her father has an alarmingly abusive temper. On top of that, she's coming to terms with the worst power in the world: when she gets scared or imagines monsters they materialize and terrorize her. But she also has an imaginary friend, called Giggleberry, who's also a hulking monstrosity that protects her.
