Tutu is trapped in a valley of eternal winter, populated by talking animals and ruled by an oil-sputtering robot Emperor.
She’s sick of doing the Emperor’s bidding, toiling in a factory that only hurts the valley with its pollution. Does the mysterious butterfly that follows her in dreams and waking life, the one that everyone is desperate to get their hands on, hold the key to the valley’s future? If she can band together with a talking cat, rabbit spies, and a masked daredevil known as the Flying Bandit, her dreams could have the power to shape the world!
