The pattern for the frog quilt is called Splash Dance. It's in the Twosey-Foursey Quilts book by Cathy Wierzbicki. Published by Martingale & Company. Page 52-56. I got it at a local quilt store about 2 years ago. If you can't find it I'll type the directions. I guess it would be against some copyrites to just copy it out of the book?
The other log cabin quilt with appliqued big frog is was at Clotilde web site and another frog pattern that is adorable but I haven't gotten to that one yet. HAVE FUN!
