I finally the SSWC dragon puzzle and the geckos, too, for my grandkids. I did not do the inside lines on the geckos. Might do later, or just omit. The kids won't care and It looks fine to me. I also could not believe they suggested MDF for the gecko. Not so good and healthy for kiddos. So I made them out of 3/4" hardwood scraps. Will do more as I work on other things. I made a stencil out of plywood, so I can make the pieces as identical as possible.
