In "Schooltown Follies," Miss Langtree's school for Civilized Animal children is under threat of being closed due to a lack of funds. In the end, Greg comes up with a plan to save the school on the fly: Use the students' musical talent to hold a benefit concert. And it works!
Miss Langtree spends most of the episode sadly reminiscing about her lover, Jimmy Brown, who has left her without word. When we find out the truth, it turns out he got a demeaning job, dressing up as a gorilla in the circus, all so he could buy Langtree a wedding ring.
Between seeing his son-in-law return and people actually contributing to the benefit concert, Miss Langtree's father tearfully comes to the conclusion that "the world truly is as sweet as potatoes and molasses".
Quincy Endicott properly meeting Margueritte Grey, the ghost lady he has fallen in love with, and it turns out that, not only is she a live person, but she returns his feelings.
The beginning of Chapter Six. Wirt is confused as to why Beatrice is "uncharacteristically wistful" because of her thinking about her soon-to-be betrayal, unbeknownst to anyone else, and decides to join in with Greg's song "To Adelaide" in order to cheer her up. Even though it doesn't work on her, it really is something for Wirt. He's joining in with Greg's silly antics for the first time, and is singing along without a hint of embarrassment. He even punctuates the song by falling on the floor, laughing aloud for the first time in the series.
This one gets even better when you've read the comics. In Issue 3, Greg urges Wirt to dance with him, to which he declares, "I wouldn't be caught dead dancing around holding hands with my little brother!," even though, as Beatrice points out, there's no one around to see except Greg, herself and some weird animals. He's come a long way.
The pleased look Greg shoots his frog at this point deserves mentioning, too.
The frog turning down a job offer, so he can stay with Greg and Wirt.
After Wirt gets rid of the cannibalistic spirit, Auntie Whispers suspects that Lorna will leave her now, but Lorna wants to stay with Auntie. For such a strange looking little family, it’s definitely a loving one.
Lorna in general. She's very sweet, as is the crush she and Wirt seemed to have on one another.
The duet, "Like Ships", between Wirt and Lorna that plays as he's helping her clean is short but adorable.
Despite his intimidating presence, Enoch cares deeply about his townfolks and looks over his celebrating citizens and muses "what a wonderful harvest."
For that matter, just the fact that the dead people who live in Pottsfield have a pleasant community where they enjoy the harvest together and happily socialize and make music with their friends and neighbors is very sweet in itself.
Enoch and Pottsfield appear to be a much more pleasant counterpart to The Beast and the Unknown. Enoch rules his citizens not with fear and despair as the Beast does, but with order and compassion. Instead of being untamed woods filled with wild creatures and lost people fending for themselves which is literally called The Unknown, Pottsfield is organized and bustling with farmers and their domesticated livestock and pets. Everyone is genuinely welcoming to the boys though they are strangers, because potter's fields had to be open to all unrecognized bodies or to the dead whose families couldn't afford a funeral. Not to mention the fact that they are not transformed into trees and chopped down for wood, but simply lay buried in the ground until all that's left is their skeletons, then they're dug up again and reanimated with their memories and personalities intact. Basically, the view of death as a celebration of life rather than a nasty, unexpected end with no bodies to be found.
Even when Wirt is getting cranky and pessimistic about being lost in the woods, ever optimistic Greg still covers his big brother with a blanket of leaves when he goes to sleep.
Doubles as a Tear Jerker, but Greg doesn't hesitate to turn down the chance to go home by himself because he's not willing to leave Wirt behind to succumb to his own despair. Even if it means making a Deal with the Devil, Greg is determined to get both him and his brother home. Or even just his brother.
"Oh, you wonderful mistake of nature!"
The fact that back in the real world, all of the kids in the cemetery decided to stay around and look for Greg and Wirt, saving their lives in the process.
"Our frog."
The Woodsman realizing what the Edelwood oil really is, angrily turns against the Beast, declaring that his daughter wouldn't have wanted this, and desperately tries to free Greg from the roots. For all his creepiness, he is a good man.
Earn Your Happy Ending is in full effect after the events of the last episode, as you get to see the fruits of Wirt and Greg's assistance all over the Unknown. Special mention goes to the Woodsman, who comes back to his home only to reveal that his daughter- the one who he'd been trying to save in the Unknown for the longest time- had been alive and well, worrying about him and asking why he's outside.
Beatrice and her family are human again, living in their old home (the abandoned mill from the first episode) and she got her dog back.
Beatrice's family doesn't resent her for turning them into bluebirds. In fact, they like to lovingly tease her and laugh about it.
The ending song. The loveliest... lies... of all...
The fact that despite Wirt's paranoia of, among other things, being persecuted by his stepfather and his half-brother for his hobbies, they are both in fact extremely supportive of Wirt's interests, even encouraging him to join the high school marching band so he can spend more time with Sara. For anyone who fears persecution from their step-family, this subversion of that trope is quite sweet and welcome.
Wirt gives the impression that he's a "loser" where he comes from and that nobody likes him. None of that is true—Sara and all of her friends are always happy to see him and want him to spend time with them, but he's too insecure to see it.
In the comic "Soulful Symphonies", Sophie, who felt she was untalented, summons demons Mezz and Altmira, who fed on the souls of the townsfolk. They start by draining Sophie's supportive mentor, Mr. Tenario, who wanted to help her and even wished he could give her his talent. With Wirt and Greg's help, she finally sings a song and banishes the demons for good. When the souls of the townspeople appear before her (having previously attacked her under the influence of the demons), Sophie asks for their forgiveness. Mr. Tenario and the rest of the townspeople appear as they were, with Tenario holding Sophie's hand, smiling as he tells her to keep making music before the spirits all embrace her, giving her their talent willingly and finally fade away, free of the demons' hold.
