Super Hero Alliance X PBS All-Stars X Little Einsteins: Firebird Rescue
During their adventures, the Super Hero Alliance are now relaxing and Robert wanted to meet his childhood friends, the Little Einsteins who were having a reading party. During the reading party, Rocket shares his favorite story with the quartet and the heroes: "The Firebird." The storybook contains animated illustrations showing the Firebird's spreading of music in Russia wherever it goes. However, a wicked ogre, Katschai, traps the Firebird and lock inside a cage on top of a building by Katschai himself, which silence all music in the nation and to the entire Russian Kingdom. Now, it's up to the team along with the PBS All-Stars characters of Nature Cat, Wild Kratts, Hero Elementary and Let's Go Luna to save the Firebird from the ogre's clutches and bring music back to Russia before Katschai strikes!
But, when a certain destroyer from the Kamen Rider Build Series and three Renaissance monsters from Kamen Rider Ghost Series wanted to use the Firebird's music power for evil, our heroes along with all the PBS Kids All-Stars must battle and save the PBS Multi-Verse and their Multi-Verse from harm.
