The girls meet a new magical girl, Usagi!  But when the new girl turns out to be a monster, they'll have to become "a magical girl who's anxious to fight the enemy that's right in front of them, and a magical girl who's started to get worried about things at the worst possible time, and a perverted magical girl who's getting excited to realize that he's actually a boy!"  Can they break out of the spell and transform by giving a plausible explanation for what they'd do with 150 crabs?
Tell me how it feels to wake up and 
find that there are 150 rare crabs
أخبرونا بشعور الاستيقاظ والعثور على 150 سرطاناً نادراً
Sagt mir, wie ihr euch fühlt, wenn ihr
aufwacht und 150 seltene Krabben …
Transformez-vous en vous imaginant 
trouver 150 crabes rares au réveil !
Trasformatevi dicendo come vi sentite
scoprendo al vostro risveglio
Digam como se sentiriam acordando 
num quarto com 150 caranguejos raros
