Osaka dreams about Chiyo's pigtails twice in this chapter, first of them being detachable (this later became the basis for the plot of Azumanga Daioh: The Very Short Movie) and then of them also being replacable. She also dreamed about Chiyo's pigtails earlier.
Tomo asks Osaka if she is going to work at Magnetron Burger again over winter break, in reference to Osaka and Chiyo's summer job.
Osaka and Chiyo go to buy a new picture book about pandas, which Sakaki is also very interested in.
Osaka says she saw a panda on TV.
Yukari cancels her English class for a P.E. lesson, and they play soccer. Yukari says she is going to "be" Hidetoshi Nakata, a famous soccer player.
Yomi asked Tomo to record a show for her, since her VCR was broken, but Tomo forgot about it.
Tomo talks about the old Japanese name for December, and wants Yomi to reply her like in a comedy show. Osaka sees the significance of this.
Osaka talks a whole lot about the issues with the Christmas carol "Rudolph the Red-Nosed Reindeer".
The girls go to sing karaoke together. Sakaki's singing ability is compared with that of a pop star.
Kimura shows up as if from nowhere and refers to a "white Christmas", like in the song of the same name.
We do not find out what show Yomi wanted Tomo to record.
It is unknown from where Tomo got the idea that Magnetron Burger used cat meat for their burgers. Yomi rejects the theory at once.
We do not know when exactly Tomo saw a panda in real life.
Yukari asks Tomo to answer an English problem, but they do not say what the problem is.
Osaka asks the others if anyone of them has a boyfriend, but no one replies, hinting that they don't.
Chiyo is nervous about singing karaoke, but it is not revealed how good she and Osaka are at singing (in the anime, Osaka's a decent singer, though).
Someone calls one of the girls a bad singer. The person referred to is most likely Yomi, in which case the person addressing her would be either Osaka, Chiyo or Sakaki.
Where Kimura comes from all of a sudden is left to the reader's imagination.
Osaka's two bizarre dreams about Chiyo's pigtails.
We see here how worthless Tomo is at cleaning because she doesn't even bother trying.
The girls' Christmas celebration, consisting of "walking around", "going to karaoke", "eating cake at Chiyo-chan's house" and a slumber party. Though only the first two activities are actually included in the chapter.
Yomi is a terrible singer, while Sakaki is very talented.
Whatever it is, it's not a panda.
— Chiyo (on the panda drawn by Osaka)
I'm getting tired of only ever teaching English! TODAY, YOU'RE GETTING A MATH LESSON, COURTESY OF ME!
SENSEI! THAT'S YOUR OWN TEAM'S GOAL!
— Yomi (to Yukari)
Was it black on white, or white on black?
— Osaka (to Tomo, on the panda she had seen)
You see … They're new ones!
— Chiyo (on her pigtails, in Osaka's dream)
When I look out and see all my friends cleaning … It just tears me apart not to be able to help.
START CLEANING, THEN!
— Yomi (to Tomo)
Chiyo-chan is already near the top of the school year! Of course, none of this stuff is going to help you out in the real world.
You all know Rudolph the Red-Nosed Reindeer? That's messed up, y'know? Sayin' his nose will help light the way ain't no way t'make him feel better about it. If you told a bald fella you needed the light reflecting off his head to see, he'd like to punch you.
Santa's a cruel bully.
She can study and play sports with the best of 'em, but she can't sing worth a lick. This girl.
