Ghost Gas was anti-ghost spray in a can invented by Tracy the Gorilla. When Fangster was haunting young Copernicus Randall's telescope, Tracy sprayed the telescope with Ghost Gas, causing the werewolf of the future to have a coughing fit and reveal himself. Eddie Spenser Jr. then used the Spectre Snare to entangle Fangster. Unfortunately for Eddie, Fangster fled out the bedroom window, pulling Eddie with him, as well as Tracy who came to Eddie's help.
Ghost Gas first appeared in the episode My Present To The Future.
