Ensemble Dark Horse: Maggie, the Emo Teen birthday girl at the end. This episode is her only appearance in the show so far, but she proved so popular among the fans, there's plenty of fanart and fan works written about her, often shipping her with either Lincoln or Luan (despite, again, her birthday party being their only interaction).
Rescued from the Scrappy Heap: Luan started developing some hate with her actions in April Fools Rules. Fortunately, this episode showed her in a much more positive light.
"Snow Bored"
Unintentionally Unsympathetic: Lisa. Her wanting to cancel the snow day can be attributed to her not understanding the concept of fun. But melting Lana's snowman with her robot and her relentless assaults on her siblings with snowballs definitely cross a line. It also doesn't help that it was a Batman Gambit to make her siblings want to go to school.
