Jack tries to save a peaceful tribe that move constantly due to an opposing food-stealing tribe of monkey/lions: Jack meets up with the Monkey Boy who can ""jump good"" almost to the point of flying. Jack is taken to his village and agrees to teach a... (more) group of furry creatures to fend for themselves in return for ""jumping good"" lessons. Jack teaches the creatures to use bamboo to fight and together they set up an array of traps for the monkey/lions. In return Jack has an challenging time trying to ""jump good"", a process involving climbing hills and vines... with boulders attached to his body.
