Krillin manages to maneuver the air/sub ship to the location where the dragon ball is. General Blue plans to tail Goku, while another squad heads to Roshi's Island. Despite their searching, Bulma, Krillin and Goku do not find the dragon ball on the ocean bed. Meanwhile, General Blue prepares and launches all his forces. As Krillin drives the sub into a cave, General Blue's submarines tail and attack them. Krillin makes it to narrower caves, but General Blue sends his mini-subs to pursue them.
