Translation of "обросли" in English

Придя в себя, я ощутил, будто пальцы и колени обросли мехом. Когда слегка посветлело, я взглянул на своё отражение в горном потоке и увидел, что стал тигром.

When I regained my senses, it seemed that fur had grown on my fingers and knees. When it became slightly brighter, I looked at my reflection in a mountain stream, and I realized that I had become a tiger.
