From the designer, Cheech:

This pattern is a product of always tinkering with sculpin patterns. I love how my old sculpin toad swims, but I wish it were a bit simpler to tie. I literally had this idea come to me in the middle of the night and I rushed to work, ran upstairs to my vise, and cranked a few out as concepts. After a bit of tweaking, this is a super simple pattern swims just like a sculpin. I also tie these in tan and brown, but I bet it would be good in many colors and sizes
