Badsmell is Nell's cat, she is first seen in Skeleton on the Dunny when Linda points her out to Bronson stating "there's your ghost".
After getting in his way while working, Tony tosses Badsmell off his latest artwork. When she lands on the "FF" (fast forward) button of the TV remote it sends a fly zooming around the room. When Pete picks up the remote, points it at Badsmell and pushes "pause", she pauses. Not knowing what Pete had just done, Tony, Linda and Bronson believe she is dead. Tony goes to tell Nell that her cat is dead while Pete explains the remote to his siblings. Pete points the remote at Badsmell again this time pressing "play", and she begins to move again, which is when Tony comes back with Nell.
