* BrokenBase: Plucky's treatment throughout the movie is either incredibly unfair or a KarmaHoudiniWarranty for being a jerk.
* EnsembleDarkHorse:
** Bimbette Skunk. She only appears for a brief few seconds to serve as the catalyst that pushes Fifi past her RageBreakingPoint with Johnny, but going off most {{Fanon}}, you'd swear she was a major character in the show.
** The insane hitchhiker who attacks Plucky in the car. On one of the regular episodes (a music video collection featuring a take on "Yakkity Yak"), he was also an escaped convict who hides out in the laundromat while Plucky is cleaning clothes. He also appears in the third-season episode "Goin' Up" (where Baby Plucky is obsessed with a mall elevator), which is also animated by TMS (like this movie was).
* HarsherInHindsight:
** Plucky predicts that they will reach Happy World Land on April 6, 2021. Creator/JoeAlaskey (Plucky), Creator/DonMessick (Hamton J. Pig), and Creator/JonathanWinters (Wade Pig) did not live to see that date, so it's fortunate Wade turned down Plucky's theory and got them to the Park much, much sooner.
* SugarWiki/HeartwarmingMoments: Babs' and Buster's little moment of ShipTease towards the end:
-->'''Babs:''' Oh, Buster, I didn't think that I'd get a chance to tell you...\\
'''Buster:''' Shh! [[IUhYouToo I feel the same way]].
* HilariousInHindsight: Buster and Babs tell Franchise/{{Superman}} to get his own video. A few years later, ''WesternAnimation/SupermanTheAnimatedSeries'' aired. [[Creator/TMSEntertainment Not only did it have the same crew as]] ''WesternAnimation/TinyToonAdventures'', but the 3-parter "[[Recap/SupermanTheAnimatedSeriesS2E16To18WorldsFinest World's Finest]]" originally premiered as a television movie in prime time, which was then almost immediately released on home video as ''The Batman Superman Movie''.
** Two decades later, [[Creator/TMSEntertainment the same crew]] made ''WesternAnimation/SupermanVsTheElite'', there were other DirectToVideo Superman movies, but most of them were done by other studios (like Creator/MoiAnimation and Creator/LottoAnimation, both of which are in UsefulNotes/SouthKorea).
** Some combination of Harsher and Hilarious is that Plucky's questionable calculation of when they would arrive at Happy World Land lands him on "April 6th, 2021." Meaning that, in what is already a road trip comedy of errors, they would arrive at an entertainment park still in the midst of lockdown and the place would be closed.
** The Happy World Land theme song mentions that tickets cost $80 a day, which was considered comically expensive in 1993. 30+ years later, a ticket to Disneyland (of which Happy World Land is an {{Expy}}) can easily exceed twice that amount during peak season.
* MandelaEffect: The title is frequently misremembered as "How I Spent My Summer Vacation". That was actually its WorkingTitle until it changed later in production, but people still tend to think that's the actual title.
* MemeticMutation:
** The spoof of the infamous Creator/{{THX}} promo and Deep Note: "THUD: The Audience is Now Deaf".
** When looking at the map, Plucky predicts they will reach Happy World Land on April 6, 2021. On that exact day, Twitter user [[https://twitter.com/Yotomoe1/status/1379304410900271105 Yotome tweeted the clip]].
* TearJerker: The treatment Johnny Pew gave to Fifi after all she went through. Unlike many other series, there were no gags or slapstick (even Fifi's ''journey'' in trying to meet Johnny were filled with slapstick on her expense), and when Johnny declared (and lied) that he did not have any pens to give her an autograph, for this very once, Fifi actually [[OOCIsSeriousBusiness cried by screaming loudly first]] instead of just her usual 'Le boo hoo' or the likes. All of it just to underscore how miserable Fifi is with the treatment of Johnny. Though it builds up for [[Awesome/TinyToonAdventuresHowISpentMyVacation her awesome moment]] to shine more.
