The Mystery of the Mummy's Curse: The Greenfield Museum is holding a special exhibit all about ancient Egypt, and the main attraction is a 4,000-year-old mummy! But ever since the mummy arrived, nothing’s gone right for the museum or its workers. Could the spooky sarcophagus be behind all the bad luck? The Mystery of the Star Ruby: The Boxcar Children have entered the Ruby Hollow Gem Mine’s annual gem-hunting competition. With a little instruction and the right gear, the Aldens have everything they need to become real rock hounds! They have a natural talent for rock-finding, and it’s not long before Jessie makes a fabulous find. But before she can enter her ruby in the competition, it disappears! Could there be a thief at the mine? The Stuffed Bear Mystery: When the Aldens visit Peggy and Doc Firmin’s farm, they’re in for a teddy treat: a behind-the-scenes look at a real teddy bear workshop! But a very rare and valuable bear has disappeared from the toy hospital. Now it’s up to the children to track down the teddy thief!
