Official mascot/test subject of the Ghostbusters...
A ghost living with a bunch of guys whose job it is to bust ghosts.
Better keep an eye on your meals...He happens to have a voracious appetite, even for a ghost.
Of course Peter Venkman looks forward to the day Slimer makes too big a mess so he can "zap 'im and trap 'im".
And the others are trying to stop him from doing so...but for how long?

Character belongs to Columbia/Sony Pictures
