Princess Camille, daughter of Slumberland's ruler King Morpheus, initially embodies royal formality, displaying superiority by criticizing Nemo's pajamas and misidentifying his pet squirrel Icarus as a rat, creating early friction. She later reveals humility by apologizing for these remarks, showing genuine kindness beneath her proper exterior. As the King's only child, his royal duties leave her lonely, prompting him to summon Nemo as her designated playmate. Their bond deepens through explorations of Slumberland, eventually blossoming into love. While generally kind and sympathetic, Camille maintains consistent hostility towards the clown Flip, blaming him for his reckless behavior in tempting Nemo to unleash the Nightmare King, which led to her father's capture. Her anger manifests physically when she punches Flip after he blows cigar smoke into her hair. Despite this disdain, she demonstrates concern for Flip's safety during peril in Nightmare Land. Following her father's capture, Camille actively joins the rescue mission to Nightmare Land. She displays leadership by compelling Flip, under threat of banishment via cannon, to guide the group using his map after he initially withholds it. Her resolve underscores her role beyond typical princess archetypes. During the journey, she, Flip, and Professor Genius are captured by the Nightmare King's minions, requiring rescue by Nemo and the Boomps. She witnesses Nemo's apparent self-sacrifice to defeat the Nightmare King, experiencing profound grief before his revival by King Morpheus. After the Nightmare King's defeat, Camille accompanies Nemo on his return to the waking world via dirigible. She expresses gratitude for their adventures and initiates a first kiss, solidifying their romantic relationship as an official couple. Her connection to the real world is hinted through a counterpart: the circus director's daughter.
