The Cheese ExperimentUnknown - 2016
When you're with Geronimo Stilton, it's always a fabumouse adventure!
New Mouse City was in a panic! A strange epidemic had broken out. Mice everywhere - including me, Geronimo Stilton - were covered in weird blue pimples! I immediately called upon Mouse Island's most famouse doctor and researcher for help. He set to work with his team to find the cure. . . but someone was trying to stop him. Moldy mozzarella, I didn't want to be blue forever!
