I'm looking to replace a children's video that my son used to watch but I don't remember the name. It was half live children, half animation. It was a little girl and little boy playing in a park. The park was actually Indian Boundary park in Chicago. I thought the vhs was put out by fisher price or playskool. One scene that I remember is the kids faces were in the windows of an animated submarine. Please help he wants it for his son Does anyone remember this video? Or does anyone know a site that I can look for old children's vhs tapes

The only half live children, half animated movie I remember growing up was called "Water babies" , but that was set in England?
