These little Mini Goopers were pretty fun. They came packaged with the classic RGB Ectoplasm Tub. (I think this is the first appearance of Ectoplasm as well) But nevertheless these guys were cool. You would fill them up with the Ectoplasm and then they would break apart down the middle like an egg and ooooooze the stuff all over the place. These guys and the Ectoplasm were some of the better ghosts in the series.

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.
