These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: My Little Pony: Friendship Is Magic S2 E16 "Read It and Weep"
Fridge Horror: One of the things on Rainbow Dash's plate at the hospital is a cube of jello. Um, gelatin is made from... what... again? Hypromellose.
Genius Bonus: Ahuizotl isn't just some random name the creators pulled out of their plots; it's an actual creature from Mesoamerican tradition, and it usually looks like... well, like a weird-ass scary dog-thing with a hand on its tail. Now, how many little kids - heck, how many ADULTS - do you think would know what that is?
Rainbow Dash's confusion over the character might not just be his sudden appearance, but a lampshade hanging of this fact.
Despite being uttered by Rainbow Dash who tends to Buffy Speak, "unputdownable" is not only in the dictionary, it is often used to refer to books.
Snoring Rainbow Dash may well beat out the FAIC here.
The death trap, which combines multiple phobias (walls closing in, bugs, snakes and drowning) in one evil package, is extremely scary and nasty compared to similar perilous situations in other kids' shows.
They Wasted a Perfectly Good Plot: An episode about Dashie breaking her wing? That's an amazing idea! Think of the drama she would go through, wondering when she would fly again, being forced to live the life of an Earth pony until it heals...for one day. The bulk of that time is spent reading about a Rainbow Dash expy that does have to find a way to function without her wings. Likely not used because Dash breaking her wing and being forced to live the life of an Earth pony has become a Dead Horse Trope among fans.
