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. Finally, when they are about to surface, a coffee mug that was in the cabin transforms and cuts off Joseph's artificial hand.
But I can't make the necessary 
preparations to dive with this hand.
ولكني لا أستطيع أن أتجهز بدون يدي الصناعية
Aber ich werde mit dieser Hand
keine Vorkehrungen treffen können.
No podré prepararme bien 
en estas condiciones.
No podré prepararme bien 
en estas condiciones.
Ce n’est pas pratique de mettre
l’équipement avec une seule main.
Senza la mia mano artificiale farò un po' fatica
 ad indossare l'equipaggiamento!
Sem a minha mão, não 
tenho como me preparar...
