Juju receives his friends in Conservatória, a city in the interior of Rio de Janeiro known for its musical nature. They, together with the train driver Lucrécio, will discover the beauty and charms of this bucolic city until they come across a great mystery involving an appearance of an indigenous person in the "Crying Tunnel". When they enter the traditional Locomotive 206, through a charm on the machinery's bells, they end up making it work and are teleported to the past. There they discover the mystery of the Indigenous Araris Itu and that the entire nature of the future is threatened by order of the evil and greedy Zé Viborus.
Musical Journey is inspired by the Literary Work Juju and the Enchanted Locomotive and features minigames, which make immersion in the plot and content a fun, playful and educational experience.
