Squatting Tiger, Hidden Dog / Muted Muriel

S4, E8: "Squatting Tiger, Hidden Dog" The family is taking a tour of the Great Wall of China, led by their tour guide, Di Lung. Muriel is suddenly abducted, orchestrated by Di Lung in the service of his godmother: the Empress Dowager of China. The Empress has kept the people of China in her thrall, but now the secret source of her power -- the magic silkworm -- has transcended to another world. The only way the Empress can contact the silkworm is through the bones of a genuine soul... and Muriel, innocent source of tranquility, is that soul. Courage must find a way to rescue Muriel before her bones are extracted. "Muted Muriel" Each time Muriel gives her opinion about something or makes a comment, the Farmer ignores her. The Farmer's carelessness hurts Muriel so much she refuses to communicate to anyone. Her resentment makes her mute. Courage hires Shirley the Medium to conjure up a spell that will make Muriel talk again. Shirley's spell conjures up giant earth-crawlers which converge on the Farmhouse. The only thing that will stop them is the sound of Muriel's voice. Courage must save them all by getting Muriel to speak.
