The Toyman creates a device that can send anyone into the world of a storybook. He tests it out on "20,000 Leagues Under the Sea", and it works perfectly. It takes him right into the underwater world of Captain Nemo and the giant octopus. Soon, he and the Legion of Doom are using the device to trick the SuperFriends inside. Toyman lures Hawkman into "Jack and the Beanstalk", where the winged hero encounters the giant of the fable. Cheetah tricks Wonder Woman into "Alice's Adventures in Wonderland". Brainiac traps Superman in "Gulliver's Travels". The other SuperFriends soon discover what has happened, but they must act quickly. After twelve hours, the SuperFriends will be trapped in the books forever.
