Dr. Dischord, just before the Valley of Silence

"I am KAKOFONOUS A. DISCHORD, DOCTOR OF DISSONANCE," roared the man, and, as he spoke, several small explosions and a grinding crash were heard.
"What does the 'A' stand for?" stammered the nervous bug, too frightened to move.
"AS LOUD AS POSSIBLE," bellowed the doctor, and two screeches and a bump accompanied his response. "Now, step a little closer and stick out your tongues.
"Just as I suspected," he continued, opening a large dusty book and thumbing through the pages. "You're suffering from a severe lack of noise."
He began to jump around the wagon, snatching bottles from the shelves until he had a large assortment in various colors and sizes collected at one end of the table. All were neatly labeled: Loud Cries, Soft Cries, Bangs, Bongs, Smashes, Crashes, Swishes, Swooshes, Snaps and Crackles, Whistles and Gongs, Squeaks, Squawks, and Miscellaneous Uproar. After pouring a little of each into a large glass beaker, he stirred the mixture thoroughly with a wooden spoon, watching intently as it smoked and steamed and boiled and bubbled.
"Be ready in just a moment," he explained, rubbing his hands.
