Realizing that the task may not be easy, Hubie comes up with several ways to chase Claude out, all of which are designed to drive him crazy, having Bertie do each of the tricks.
When Bertie is yanked back up the chimney and the pump is released, Claude ends up flying all over the living room, hitting all of the walls and ceiling before landing hard on the pillow on which he was resting.
Claude then takes the bottle of Nepeta he had hidden in an overhead lamp, tosses it out the window, and inaudibly mutters the Pledge of Sobriety.
With the logs removed from the fireplace, Hubie lowers Bertie and a dog (resembling Hector the Bulldog) in a doghouse down the chimney.
Finally broken, Claude runs, screaming, from the house and hides in a nearby tree, trembling in the leaves.
Having accomplished their mission, Hubie and Bertie return down the fireplace and roast cheese over an open fire as the cartoon fades out.
