Three best friends, a magical musical world and countless adventures - that's the Lalalinos. Get to know Cosmo, Scout and Akio and let yourself be carried away by their enthusiasm and love of music. This Tonie contains four musical adventures and great songs from the best band in Bumbaloo. Scout plays her new harmonica incessantly until she finally swaps it for a new instrument. Akio combines his two favourite pastimes into a new creation: the Xylo book. Cosmo invents a funny rhyming game with a balloon. And at the "Treasure of Bumbaloo", Akio finds a mysterious musical treasure map that leads the Lalalinos once through the whole of Bumbaloo.
