I, Geronimo Stilton, must travel through time once again! The mouseum was being awarded the Petrified Cheese Prize, an award given to the best mouseums in the world. We were celebrating at a big party when three artifacts went missing. There was only one solution! We had to travel into history to find the missing artifacts and bring them to the present. My friends and I climbed into the latest time machine for another adventure! During our mission we met a young Alexander the Great and Queen Cleopatra. We battled pirates, and we even watched Mozart create new music. Could we collect the relics and make it back to the mouseum in time to win the award?
