Congo Jack was a big game hunter kidnapped by the Mole Men for their games. While in their kingdom, he became Queen Moletta's object of affection as well as the ambitious Lugi's object of loathing (he wanted both the queen and the kingdom for himself). Jack's enemy became allies with King Bobo and his Blue Dwarfs. In the end, however, Bobo was killed, Lugi imprisoned, and Jack returned to the surface world.
