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.
Rainbow Dash: Oh you want to do this the hard way? we do this the hard way!
Trivia: Pinkie Pie didn't use the trombone to get rid of the parasites. That means she planned for the exact ending. Not unlikely, considering Pinky Sense.
The Elements of Harmony (2) - S1-E2
Question: When Rainbow Dash and Fluttershy are floating with Twilight, Nightmare Moon, (In the form of smoke) floats right in Twilight's face, though she never notices it. Why is that?
Answer: The smoke floats a few feet away from Twilight and close to the camera so you might think that the smoke is right in her face.
