Where can I by garden eggs? (Watertown: shoppers, market, water)

[JEFR]

I have a friend who is here from Nigeria and she is searching for garden eggs. From what I've seen on the Internet, it's a mini-eggplant that looks white or yellow. Any ideas? (The closer to the North Shore, the better.) Thanks!
