Otao is in the nurse’s office due to anemia.
Feeling better, he tries to go back to class but decides to take a detour to the deserted hallway. While walking in the quiet hallway, he discovers wet towels on the floor..
to the moistened sea sponges that Romans used.
إلى إسفنجات البحر الرطبة التي استعملها الرومانيون
bis hin zu befeuchteten Meeresschwämmen,
die die Römer nutzten.
Dans la Rome antique,
on se servait d’éponges et de galets.
per finire con le spugne marine
 che usavano i romani.
até as esponjas do mar, dos romanos.
