Conrad and Sally resign themselves to facing the consequences when Joan comes home, but the Cat (having a change of heart) returns with a cleaning invention and fixes the house; Conrad and Sally reconcile with the Cat and thank him for everything before he departs and Joan arrives. Larry, covered in goo, also returns in the belief that he has busted the kids, but when Joan sees the clean house, she doesn't believe his story and dumps him, much to the delight of Conrad and Sally. After the successful party, Joan spends quality time with her kids by jumping on the couch with them while the Cat and Things 1 and 2 walk off into the sunset.
