Unfortunately, they don't know how to get into the pyramid to meet him, so they have no other choice than find their way all by themselves, like Egyptologist. Grisù manages to use and decrypt the pharaoh's secret motto. They finally find Smeraldo. Grisù helps him to overcome the final obstacle to eventually discover the marvelous sarcophagus of Thudnose!
