Auzou Book for dinos on the run

After the plot devised by the Norbert family, the Zorus family had to leave the dinosaur farm. To make matters worse, the management is now handled by the Norberts themselves. As silly as they are wicked, the Norberts are causing disasters and letting the dinosaurs escape all over the village. The mayor begs Tilly and her parents to take control of the situation: but will they manage to recover all the fugitives?
