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.
Fanon: The names of the three Pigs. Fans often use the names Lloyd (Pig 1), Floyd (Pig 2) and Boyd (Pig 3). Kevin Gillis says that their names are Lloyd, Lloyd and Floyd. However, on the show itself, each of the three is, at some point, referred to by name by one of the two others as Lloyd (meaning that all three are named Lloyd).
Growing the Beard: The series gradually shifted from clichéd plots and characters in the early seasons to much better writing in the later ones that had real soul and originality that took creative dares for a kids' series. The only problem was that they never changed the opening sequence, so the intro still portrayed Cyril as evil and Bert as a cartoonish klutz.
Harsher in Hindsight: While the outcome of "The One That Got Away" does serve as a harsh reminder about taking care of the environment in itself, it is made worse by Bentley's observation at the end: "It's up to us! WE'VE got to change things!" Years later, you could notice that we haven't been doing a good job at it so far. Of course, you could still made this observation about any environmental message made in any era.
Especially prevalent in some of the earlier episodes, particularly during the scenes at the top of the Evergreen Mountain in "Going It Alone", as well as in one scene in "The Runaways". Also not forgetting the haunted house in "A Night To Remember".
"The Evergreen Election" ends with an unnerving extreme closeup of Cyril's slightly bloodshot angry eyes glaring at the viewer.
One-Scene Wonder: This show was full of characters that appear only during one episode and never to be shown again, but sometimes the plot they bring could be quite significative and touching, even serving for Character Development for someone from the main cast.
Tear Jerker: The outcome of "The One That Got Away" is a great example, not only for the fact that such a beloved water area gets ruined, but for the fact that some people never got the chance to experience it. Taken Up to Eleven when the ending shows a montage of the characters who all have memories of the place hanging out there in their early years while Lisa Lougheed's "Ain't No Planes" plays. After the montage ends, there's a brief showing of areas in the Evergreen Forest, and as night falls, we get one final shot of Bentley, who never got to have memories of the place, alone looking out over the pond.
