Plot[]
Happy mice and cockroaches are looting a kitchen full of goodies. When the housecat goes out for some romance, mice have a party and cockroaches hold a dance. The mice all mount a marvelous musical production of "Little Brown Jug," and then partake of the alcoholic beverage! Then a troupe of cockroaches sing and dance to "La Cucaracha." And then... a giant, mean rat shows up to spoil the fun. The rat decides to make a cute girl mouse his own- until the cat returns, that is, just in time to send him packing. Cat and mouse retire to their separate quarters.
