The Amusement Park Mystery: The Aldens are going to visit their cousins Joe and Alice. To the children's delight, Joe and Alice live near a wonderful amusement park. The park holds everything the Boxcar Children could ask for — a beautiful merry-go-round, lots of rides and games, all the cotton candy they can eat . . . and a mystery!

The Mystery of the Mixed-Up Zoo: The zoo is wonderful — it has seals and giraffes and elephants and tigers, and Benny's favorite, a little monkey named Amos. It also has a mystery. Someone is mixing up signs, switching off electricity, and endangering the animals' lives. If the Boxcar Children want to save the animals, they'll have to solve the mystery — and fast!

The Camp-Out Mystery: Grandfather is taking the Aldens on a camping trip. The children enjoy the camp-out — setting up the tent, hiking in the woods, and especially making delicious food over the campfire. But some strange things begin to happen. Loud music plays in the middle of the night. Their lantern disappears. And then they receive a frightening note. It looks like the Boxcar Children have another mystery to solve!
