The show has now moved to the NBC network, which broadcasts in color, but this episode begins in black and white. Walt Disney chats for a while before he notices the lack of color. He apologizes, snaps his fingers and says "the magic words-N.B.C. T.V.!" to switch on the color. Walt recalls the impact Technicolor had on movies, then introduces Ludwig Von Drake, who "explains" how color television works. Von Drake plays a special pipe organ which produces color instead of music, and gets in a tussle with the N.B.C. Peacock. The second half of the episode is the featurette "Donald in Mathmagic Land," in which Donald Duck travels through a land of mathematical wonders.
