The first of the serials, The Mystery of the Applegate Treasure, aired on The Mickey Mouse Club in 1956 during the show's second season. To appeal to the show's audience, the Hardy Boys were portrayed as younger than in the books, seeming to be 11 or 12 years old. The script, written by Jackson Gillis, was based on the first Hardy Boys book, The Tower Treasure, and the serial was broadcast in 19 episodes of 15 minutes each with production costs of $5,700.

This serial, The Mystery of the Applegate Treasure, was released as a two-DVD set as part of the sixth wave of Walt Disney Treasures on December 19, 2006. A second serial, The Mystery of Ghost Farm (an original story by Jackson Gillis), aired on The Mickey Mouse Club in 1957. But the second serial has not been released as a Walt Disney Treasures set.
