A new adventure for our little prehistoric heroes Tam-Tam and Lili.

It's party time today at the playground today! The children put on a prehistoric concert with items they find in nature. Tam-Tam complains because he can't find an instrument. Fortunately, Lili is as good an explainer as ever, and takes charge of his musical education. But their music attracts a dangerous guest: a saber-toothed tiger!
