While Theodore tries to find George, Dave expresses his excitement about a new recording he recently finished; after it goes missing, he calls a shady detective named Private Nose to investigate. Sam begins searching for the tape, quickly blaming Alvin and even Dave for stealing it. As he searches he demands that Dave and the boys find clues for his nose. It turns out that Theodore's pet parakeet took the tape, among other things, to make a nest in a hat. In the end, Sam takes Dave's recording and leaves the house wrecked.
