This was probably the most unusual Ghost in the entire series. It was, now get ready for this, A Killer Possessed Toilet. Yes that�s right, it was a toilet possessed by a Ghost. While this was unique I doubt many people found it popular. You could take this little guy and roll him around and the toilet lid and the lid to the tank would pop up revealing a set of eyes and a mouth with grizzly fangs. There was a GB Symbol on the lid.

Well here they are, the infamous Ghostbusters Ghosts. Only trouble is the majority of these Ghosts never even saw screen time in RGB. Given the exception of Slimer and The Stay Puft Marshmallow man practically NONE of these Ghosts appeared in the cartoon. Regardless of their screen time or lack there-of these are still some pretty good Ghosts. Some of them are downright scary.
