First Presbyterian Church inside Emu Egg.
In The Thwarting of Mr. Dingsnapple, the zookeeper takes not only Sweetie's eggs to sell, but all the goose eggs. His reason is that a lady from the International Egg Art Guild needs 100 eggs for an egg decorating class. She plans to pay him handsomely for the eggs.
Outside of boiled Easter eggs, most people do not know about this highly advanced and challenging art form. Real eggs are emptied of their contents, cut open, and decorated in a variety of ways. Most eggers, as people who participate in this art form are called, prefer to put jewels all over the eggs. I did some of that, but my preference was making miniature scenes.
