A major investigation into the dinosaurs'; tracks, beyond the borders of space. . . . And time!
"Well done, kids! You are invited to the laboratory of the famous Professor Dino, the greatest specialist in dinosaurs. He will reveal all his secrets to you exclusively, during an exceptional open house day".
But by the time the children arrive, no sign of the teacher.
For Victor, his assistant, and for the children of the audience, it's a puzzle. Dragon hunters, strange fossils, T-Rex and bears in tuxedos: there are plenty of clues. . .
Where the hell is Professor Dino?
