- Archive Panic: Averted by the archive's arrangement by issue, and by Peter's conscious decision to keep each individual story as self-contained as possible so anyone can jump in anywhere. Electric Wonderland is the exception, being more continuity-heavy. The banners don't have their own archive, though.
- Growing the Beard: Mulberry and Electric Wonderland show greater attempts for depth than the older comics do. Art Evolution also seems apparent in all but the youngest of the flagship series.
- Anvilicious: "Vess MacMeal Starring in: The More You Know!" It seems possible this happened on purpose, since the comic acts as a throwback to cautionary stories written during the Cold War.
- Sequel Displacement: Even though Peter calls "Raiders of the Lost Arc" his favorite Platypus Comix story, he has an open hatred towards the half written in 1998. As a result, the website only features the half from 2001, set post-9/11.
- Big Lipped Alligator Moment: "My Ocarina of Time Walkthrough" has a point in which the player asks, "How do I defeat Jenova?" Instead of stating that Jenova comes from Final Fantasy VII, not Ocarina of Time, Peter fabricates instructions on how to gain the abilities to turn into a werewolf and "Omnislash". He caps off his response by warning that defeating Jenova will cause the N64 to explode.
- Harsher in Hindsight: The review of Kids' WB!'s final day includes a lament about the likelihood that World of Quest would end after 13 episodes, then never air on US televisions again "until it appears on Toon Disney at 3 in the morning in the year 2014." Not only did the second season of World Of Quest air only in Europe, but Peter just happened to write that review mere months before Disney announced they had decided to replace Toon Disney with Disney XD. On the bright side, his Exact Words don't give a completely correct prediction of the future of World Of Quest; he feared it would disappear from the face of the Earth.
- Hilarious in Hindsight:
- "My Ocarina of Time Walkthrough" claims that beating The Running Man in a race will grant the player a werewolf's curse. Five years later, The Legend of Zelda: Twilight Princess starred a Link who could turn into a wolf.
- Reading Peter write, "Spidey is red-hot and Batman is red-not. But stuff happens.", evidently unable to foresee The Dark Knight Saga rebuilding Batman's fame, and Spider-Man 3 causing Spider-Man to lose his.
- In 2004, Peter found a cartoon on Telefutura starring a homely schoolgirl named "Betty." After watching an episode, he published a review online, titled "The most obscure cartoon I can possibly review." Two years later, the character of Betty La Fea was formally introduced to America with the successful sitcom, Ugly Betty, prompting Peter to retitle the article (now called "Ugly Betty: The Cartoon Series") and rewrite the opening and concluding paragraphs.
- It feels jarring now to read this volume of "The Ancient Lost Art of TV Guide Advertising" and remember a short time when Peter would talk about Free Spirit without batting an eyelash, never mind gushing about Winnie Goodwin or desiring to write better stories for her.
- Older Than They Think: As noted in a later installment of "Worst Comix Ever!" Peter reviewed Tandy Wiz Kids #2, "Fit to Win!" years before it appeared on Atop the Fourth Wall.
- The Woobie: Reading about Peter Paltridge's real life can get depressing sometimes, especially in the article about middle school bullies.
