Amanda is portrayed as an imaginative, slightly lonely child who feels overlooked by the bustling, noisy world around her. She spends her days sketching fantastical creatures and dreamscapes in a worn-out notebook. One evening, after a particularly disheartening day at school, she makes a wish upon a "shooting star" (which eagle-eyed viewers have noted is actually a passing satellite).
