This is an interesting summary, I look forward to seeing the photos :)

I noticed that some of the locations listed seem to be similar to JumpStart Preschool (1999) locations, such as Letter Island, Color World, and Shape Land. At least the names are the same. Possibly the book takes inspiration from more than one JumpStart game.
