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?
that only exist in the amazon, 
that I saw on TV with Mom!
الموجود في الأمازون فقط، والذي رأيته على التلفاز مع أمّي
die nur im Amazonas existieren,
wie ich’s mit meiner Mutter im TV gesehen hab!
et une ammonite 
que j’ai vus à la télé avec ma mère !
tra i granchi eremita e quelli della neve
e che vivono solo in Amazzonia!
que só existe na Amazônia, 
como vi na TV com minha mãe!
