Hol Horse and Mondatta followed Jotaro and the others to Cairo and as Mondatta's book said, Hol Horse stuck his fingers into Polnareff's nose... but he didn't know what to do from there. Then Jotaro and the others, who were looking for Polnareff, show up, but things seem to be going the opposite way of the premonition.
Tell them you were about to take a piss. A piss!
قُلْ لهم بأنّك كنتَ على وشك أن تتبوَّل، تتبوَّل
Sag ihnen, dass du pissen warst.
Los. Du warst pissen!
¡Diles que querías orinar! ¡Orinar!
¡Diles que querías mear!
Dovevi pisciare!
Digli che dovevi pisciare!
Fala que você ia mijar 
aqui no canto, anda!
