Clefairy appears to be a larger and more detailed version of its pre-evolution. Its stocky arms have now gained three digits on each of its hands, two of which appear to have grown nails. Each of its feet has gained a single clawed toe and its star-shaped body has now become more rounded, giving it a more chubby appearance. Its mouth has gained an elongated left canine and it has gained a wrinkle on either side of its eyes similar to crow's feet. The curl on its forehead and tail is now larger, and its ears are now longer, slightly less rounded, and primarily pink with brown tips and black undersides. It has gained small wings on its back, which are incapable of flight. Some more basic aspects have been left the same, as they are both tailed bipeds.
