 Sylvester has been "blackballed" out of membership to the Loyal Order of Alley Cats Mouse and Chowder Club again. To gain the long-coveted membership, the Grand Master offers to let the lisping puddy tat place a big bell around the neck of the largest mouse he can find, so the cats can pounce on the mouse when they hear the bell. Just as that s going on, Hippety Hopper escapes from a city zoo truck. It s not long before he encounters the hapless Sylvester. Each attempt to place the bell around Hippety s neck ends with Sylvester wearing the bell (and the cats pounding the puddy into submission). In the end, Sylvester finally does get the bell around Hippety s neck, but by the time the cats are ready to pounce on the baby kangaroo-mistaken-for-a-giant-mouse, Hippety has been recaptured. The oblivious cats end up jumping in front of the city zoo truck! Sylvester now gets to serve as Loyal Order s Grand Master.
