There's an old thread about them on the ghostofthedoll message board. I have a few bits and pieces I've picked up randomly from op shops. If you can't find any info about them you can always make your own website to document your collection and help out any other collectors. It's easy to do (I used weebly.) There's a bit of info on wikipedia - I never even knew they tried making a third generation of the dolls. I think I remember something about Betty Spaghetty starting out as a project for a group of students or something and they thought the idea was so good that they actually made it, but I could be getting confused.
