At Obscura Antiques and Oddities, Mike and Evan are intrigued when a sleep-deprived customer stops in to unload a nightmarishly large bat -- and its huge fangs. Then, a buyer who turns century-old inventions into new, working technology with Victorian flair sends Mike and Evan on the hunt for a quack medical device that he can use as a video game controller. Later, Mike takes a chance purchasing a very creepy, mute "talking doll" created by Thomas Edison, then reunites the doll with its voice box to hear what it might have sounded like 100 years ago.
