 Another addition to this  spin-off  series --or second/third season of "The Real Ghostbusters," aside from the new characters in  Slimer s  solo-adventures, were three orphaned children. This children were sorta a younger versions of Ray, Egon, and Peter. The brain, the hot-shot, and the gadget-maker. They would occationally drop by the GBHQ station, and went by the sur-name "The Junior Ghostbusters." Personally, I thought, and felt this idea was annoying. And thankfully, they didn t show up very much after that season. They also had their own  Ecto, kiddie vehicle, and ecto-meter and gadgets.
