Jotaro and the others obtain a submarine as a new means of travel. Through the Red Sea, they try to head toward Egypt where DIO awaits. Using the sonar to detect any threats on the outside, the submarine quietly dives in. They however realize that if they're attacked underwater, there is nowhere to escape, so they are on their guard.

Nós o prendemos, ou será 
que foi ele que nos prendeu?
