In today's science class, the four girls learn about the 'green bug' which is known as euglena. Brimming with scientific curiousity, Jun can't stop wondering about what that might taste like, and agrees to go have euglena ramen with Koizumi-san. What is that absolutely foreign flavor going to be like???
What have you been mumbling 
about all this time?
ما الّذي كنتِ تتمتمين به طوال هذا الوقت؟
Was brabbelst du die ganze Zeit
vor dich hin? Das irritiert mich.
¿Qué tanto estás diciendo?
¿Qué estás diciendo?
Que marmonnes-tu depuis tout à l’heure ?
C’est énervant.
Costa stai borbottando?
O que você estava
cochichando o tempo todo?
О чём ты не переставая бубнишь?
