Tennessee, a wise-cracking penguin, and his dim-witted pal, Chumley, resided in the Megalopolis Zoo. They were constantly scheming against zookeeper Stanley Livingston and his assistant Flunky, in an attempt to raise the quality of zoo-life. Once Tennessee had his plan in mind, he was single-minded in his pursuit, exclaiming "Tennessee Tuxedo will not fail!" Once their projects failed- and they always failed- they would consult their educated friend, Phineas J. Whoopie, and his 3-D BB (a three dimensional blackboard). The 3-D BB helped demonstrate basic scientific principles through the use of instructional film clips.
