The Ghostbusters and Slimer manage to confine and trap a disgusting ghost named the Sleaze. Ray Stanz tells Slimer not to tease the Sleaze. Slimer, unfortunately, doesn't listen and ends up accidentally freeing the Sleaze from the Containment Unit when he makes the Sleaze roar with such a force that the spud is slammed against a button that shuts the grid off temporarily. When the Sleaze runs loose, Slimer gets help from the Junior Ghostbusters to recapture the Sleaze. After several failed attempts, the Sleaze is eventually returned to the Containment Unit.
