I was fishing yesterday and ran across a friendly FF. We compared fly boxes and he coveted one of my pink retrievers, so he traded me one of these

He said it was the best smallie fly ever.

He said he bought these because he could not figure out how to tie them. The tail is kinda articulated yarn with some type of wire reinforcing it. The freedom of the tail seems to be the secret.
Any ideas on how to tie?

Thanks
