Meet the world's smoothest cuddliest hedgehog. Names after brave hero, but Nelson is completely bald so when curled up he looks like an egg. Doesn't have a single prickle or strand of hair. Thought to be suffering a stress related alopecia following a trauma in the wild. Volunteers have been massaging him for half an hour a day for the last year to encourage spikes to grow. Now given up but he still gets daily massages because he enjoys them so much and to keep his cuddle skin soft and smooth. Unlike his namesake Nelson could not defend himself so will live out his days at the Foxy Lodge Wildlife Rescue in Hemsby, England. (Photo by Jeremy Durkin)
