The World Music Festival is being held in TronBon’s hometown and the judges are none other than the clowns Txirri, Mirri and Txiribiton. The night before the festival, all the instruments in the town —as well as the clowns— are mysteriously stolen.
Unfortunately the movie Tortolika & Tronbon is not yet available on HBO Max.
