[SUB] Joshiraku (2012)

As the girls have a fake summer beach trip in the dressing room, they discuss the different designs of school swimsuits. Then, the girls go sightseeing in Musashi-Sakai and pay their respects to the company responsible for animating them. Lastly, the girls have a Christmas party, but the tree that Tetora ordered online completely fills the dressing room, causing them to try and reunite (but end up fighting each other) in the Amazon-like jungle.
