从前有个人去买了一只鸟，结果回家才发现它不会飞。于是他决定教鸟飞，结果教了一整天也没学会。最后，这个人抱着鸟说：“好吧，如果你不会飞，那我们还是来学游泳吧！”A mysterious gem called the "Skull Stone" said to be able to reveal the location of the largest vein of gold in the world. This legend has entranced many people who wanted to get their hands on fame, power and wealth, including the Dorombo Gang. However, their hunt for the Skull Stone is not as easy as they imagined, mainly due to the faulty information they receive from their leader; and most of all, by a justical duo of pursuers called the "Yatterman".
