I, Geronimo Stilton, found myself travelling through time once again! While testing his latest time machine, Professor von Volt accidentally brought some history into the present. Tops, our triceratops friend, Helen of Troy, Attila the Hun, Charlemagne, and Christopher Columbus were all in present day New Mouse City! My friends and I climb into the new time machine to take them back in time. But we are not sure the new machine works perfectly! Can we return everyone to their proper place in time and make it back in one piece?
