Continuing the adventures of Geronimo Stilton and his team as they report on unusual mysteries and try to help those in need. Adventure, mystery and humor abound! A mysterious reptilian hero is making headlines with daring rescues across New Mouse City, winning over the crowd with every good deed. But Geronimo isn’t convinced—something doesn’t add up. As the Gator Samaritan’s fame grows, suspicions rise that this so-called savior might be part of a clever scheme by Sally to boost her newspaper’s sales. Is the city’s newest hero the real deal… or just another headline hoax?
