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!
