As Gokū and Bulma ride the Kintoun to the next Dragon Ball, unbeknownst to them, the Red Ribbon Army is tracking their movements, with Commander Red amazed at the speed at which Gokū is traveling. Red then notifies General Blue of Gokū's impending arrival. Bulma is eventually able to track the Dragon Ball's location, and she and Gokū land on an island.
She then finds that the Dragon Ball is likely to be underwater. As this leads Gokū offer to swim underwater, Bulma claims she as a submarine capsule, only to be shocked that she unintentionally took her father's capsule case. She then opens her father's capsule to realize that it is filled with dirty magazines, leading her to rip them in shreds out of exasperation.
Gokū then resolves to swim underwater, but cannot find the Dragon Ball. Whilst the boy quits and wonders of Bulma's whereabouts, she is chased down and shot at by the Red Ribbon Army, leading Gokū to take out both pursuers. The young boy then reveals to Bulma that he thinks Kame-Sennin has a capsule that can send them underwater and that they should head to the Kame House, much to Bulma's annoyance.
