The World's Greatest Super Friends

The Planet of Oz (1x8)

Air date: Nov 10, 1979

Aquaman, Wonder Woman, and Superman are swept away by a tornado and magically transported to a Wizard of Oz planet, courtesy of Mxyzptlk. Superman is changed into the Tinman, Wonder Woman into the Cowardly Lion, and Aquaman into the Scarecrow. After battles with crazy foes in the strange land, it's the quick-thinking Superman that sends Mxyzptlk back to the fifth dimension, and the Superfriends back home.
