Starring: Tara Strong, Tabitha St. Germain, Ashleigh Ball, Andrea Libman
Baby Cakes - S2-E13
Other mistake: During Pinkie's Piggy Dance, she pokes out between the two babies. The female baby shifts over, then a lump appears on her chest that should be her front right leg. However, the lack of a line makes it appear to be on her chest.
The Elements of Harmony (2) - S1-E2
Other mistake: At the end of the episode when Princess Celestia is talking to Twilight Sparkle you can see that Princess Celestia's tail is on top of her leg instead of in-between. It's covering her cutie mark.
Discord: 'What fun is there in making sense?"
Trivia: There are a lot of Greek references. Cerberus, Tartarus, a messengers boots (Hermes reference) and the princesses. Twilight is the Greek word for friend love, or Philia. Cadence is Eros, or romantic love. Celestia is Agape, the love God has for mankind. Well, Celestia is kind of a god. Luna is Storge, love of a mother and child. This works because she has helped Scootaloo and Sweetie Belle in a motherly way. She was a mentor to both of them.
Question: During the song, 2 cute bats are seen with 'Jude'. When the cute bat couple is shown again, Jude is nowhere to be seen. The couple doesn't look at all concerned. When Applejack was singing "These creatures have a one-track mind!", Fluttershy appeared without Jude and couldn't take him or her home and then come back in about 5 seconds. So, where did Jude go?
Answer: He wasn't there in the first place. It was probably someone else.
