To commemorate the opening of a new bridge, a musical concert is held, featuring mammoths as instruments, which ends in disaster when the Inventor cries out in pain, causing a stampede which wrecks the stage. The islanders ostracize him from the village until he can find a way to prepare a replacement concert in time for the bridge's opening. Against the orders of Frank, Olive assists him, and the pair set about building giant woodwind instruments. Topics covered: music, woodwind, brass, air flow, sound waves, instruments, vibration.
