With her happy-go-lucky attitude, her dapper dress and a missing tooth, mutation fairy flies all around the place and with gleeful joy pulls supernumerary digits, suspicious growths and all kinds of fun clinical disorders from her numerous pockets. She is a generous creature indeed. She gives out mutations to anyone and everyone without paying attention to the time of year, whether you have been good or bad, your age or where you live. Sooner or later she will visit you and in all likelihood will keep on visiting again and again. If you’re lucky, you might get something what doesn’t do much harm or might even be slightly beneficial, like a sixth finger, but you will probably end up with a whole plethora of hereditary diseases including several forms of cancer.
