In this animated update of the hit motion picture, the Ghostbusters are up to their same old tricks, keeping the city safe from demons, curses, spooks and every other off-the-wall weirdness known (and unknown) to mortal man. This time they have help from their old nemesis Slimer ("Onionhead"), a new arsenal of weapons, and an occasional assist from their faithful secretary Janine Melnitz. In 1988, the start of the fourth season, the series was part of a one-hour block of Ghostbusters cartoons (it was joined with the newly created "Slimer!" series) known as "Slimer! And The Real Ghostbusters."
