Please don't get the impression that I designed all dolls and playsets for these lines. I was part of a team of designers, whether full-time or freelance, and each of us had particular items we worked on, but rarely all. There were some lines that I entirely designed, like 2nd year Cupcakes dolls (not playsets), 3rd year Dolly Surprise, 2nd year Moondreamers (except playsets & Sun Finders). These dolls were never released.
Also know that there are many many more toys that I designed, invented, or contributed that never saw the light of day. Most of my time at Fisher-Price was coming up with new products, most of which were never produced. Also, during the 12 years I was freelancing, there were many toys I worked on that I have no idea if they were released or not. Sometimes a couple of years would go by, then I'd go to Toys R Us and see something familiar... gee, did I work on that? LOL!
