a lot of times I'll accidentally get the third piece to something else I'm looking for and so I'll dump that in the lamp to do next, and then it sort of spirals into a chain of ducks
I also found someone who uploaded screenshots of the completed ducks so I can compare some of the more subtle combos (figuring out someone like hookbeard is a no brainer but I thought I had double decker until I realized I had a similar but not exact wing)
