Anvilicious: A good part of the time, anyway. While a few of the aesops were handled with surprising subtlety, most of them fell into this.
Awesome Ego: Melody is a cocky, somewhat self-obsessed party girl with aspirations of being an actress and musician. Smug though she may be, her spotlight episodes indicate she's actually got some considerable talent to back it up.
Awesome Music: "Sweet Music", the song Melody's band the Rockin' Beats perform in "Battle of the Bands". It's a sweet, catchy tune that carries meaning when the band's performance suffers without Melody. However, the song becomes even more awesome when Melody's twin sisters join in near the end the second time it's played.
Although everyone has their favorite of the seven girls, Patch tends to be the most notable. The single tomboy of the group, fun-loving, and the sheer amount of weird things that keep happening to her have some fans convinced her past might have been explored more if a second season had been made.
Clover's sister, Meadowlark. Likely because of her Cool Big Sis persona and the only sibling dynamic to get fleshed out in the series. She appeared in all of two episodes, and it's common to hear fans wish they could have gotten to see more of her.
Among the boy ponies, Lancer since he's the kindest of the three and the most willing to be sociable with the girls.
Family-Unfriendly Aesop: "Shop Talk" is MADE of this...and of the worst kind. Hey kids! What did we learn today? Blackmail is the answer to all your problems!
"And the Winner Is..." teaches us that good fortune is something you should feel guilty over. If all your friends can't join you in something, it's better that nobody goes at all.
Fandom Rivalry: Within the same franchise, to boot. As noted above, this incarnation of MLP draws ire from some fans of the previous And Friends incarnation. Aside from that, fans of Tales are also locked in a cold war with certain brony sects (to be specific, the rabid ones who enjoy dissing anything not FiM). The latest shot fired by said bronies was taking pot-shots at the series' long-awaited DVD release in the reviews at Amazon. This was seen by many Tales fans as a particularly low blow.
Fridge Brilliance: Teddy is shown to have a fear of water in "Blue Ribbon Blues" and only the girls are shown swimming in "Happy Birthday, Sweetheart!". These make sense considering stallions have a lower body fat percentage than mares, making them more apt to sink in water and therefore more likely to drown.
Germans Love David Hasselhoff: The only plausible reason why two of the ponies from this series got a kiddie ride made after them and the show has seen home video releases in the UK and Australia. And in Australia's case, it was a complete release of all 26 episodes spread across 4 volumes. The series has had no toy releases for its home market, the U.S, and home video releases were long withheld until 2015 when other countries got them earlier.
In "Shop Talk", an annoyed Teddy kicks an apple tree, and all the apples fall down (a good deal of them right onto him, naturally.) Fast forward to FIM and this is the main method of apple harvesting used by Applejack's family. Able to harvest an entire tree in one kick? If he were in FIM, Teddy would be legendary for his "applebucking" skills.
In the song from the same episode, Clover mentions Count Appaloosa as being Madame Percheron's fiancé. FIM has a town by the name of Appleloosa which is a play on the breed of horse.
Moe: Sweetheart is caring, optimistic, and doesn't have a mean bone in her body. Her speaking voice is also easy on the ears.
Never Live It Down: The Boys, Boys, Boys song. Many people believe it to be an indicator of the show as a whole, despite it being a tiny part of the episode, has very little influence on the plot, and the girls learning to go against that mentality is how the episode ends.
Tear Jerker: The song Off You Go from the episode "Gribbet". You try not crying, especially just after losing a pet, or giving away something of sentimental value to someone else.
The Scrappy: Ace is the most hated character for not only treating girls like crap and using them for his own purposes (only made worse by the fact that the show is aimed for girls) but for also being a Jerkass in general.
Clover who shifts from being too lucky to Blessed with Suck. It's hard not to feel sorry for her.
Sweetheart in "Shop Talk" when Teddy accuses her of spreading rumors about his teddy bear. She clearly couldn't do anything to stop her friends, especially when Ace and Lancer hear about it. With everything that happens to her, you just can't help but give her a hug.
