For those not familiar with this series -- especially those who are thinking "why is there a gorilla in this gallery?" -- this is a Filmation cartoon based on the 1970s live-action TV comedy The Ghost Busters.
The live-action TV show featured two men named Spencer and Kong who investigated paranormal activity together with a gorilla named Tracy (yes, the gorilla was not named "Kong"; probably for copyright reasons). The cartoon, on the other hand, was about their sons.
Here's a clip of the opening of the TV show, in case anyone's curious: https://www.youtube.com/watch?v=CBiVBgNvYRA
