Kai, Finn, and Mia, sixth-grade friends, are called by Enigma, a mysterious walking top hat, to save Kaboom City, a fantastical world where everyday objects like skates, keys, or guitars have come to life thanks to Kazoom, the universe's most powerful energy, and have been transformed into "super-things," superheroes and super-villains with extraordinary abilities, each facing their own rival.

Princess Valentina embarks on an adventurous journey through different parts of the country. Along the way she meets mythical characters from catalan fairy tales and legends, such as Patufet, Sant Jordi, the giant Puigmal or the magician Soc.
