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?
I'll send them to the abyss of despair
سأرسلهن إلى أعماق الإحباط
Ich schicke sie in den Abgrund
der Verzweiflung,
Je vais les plonger dans le désespoir 
pendant qu’elles sont distraites !
Le getterò nella disperazione più profonda
Elas vão cair no abismo do desespero
