* AccidentalInnuendo: The entire [[https://youtu.be/nGUEFTM_J6k Hulesangen]] number. Even moreso in the Danish version, where the tones of voices are a little more... suggestive.
* AdaptationDisplacement: The movies themselves are already obscure as they are, but something that is even more obscure is the book that Jungledyret Hugo's creator, Flemming Quist Møller, wrote a few years before the first movie was released, which it follows pretty closely but with several differences.
* FirstInstallmentWins: The first two movies are generally viewed as underrated animated classics, while the TV-show and the third movie are viewed as downgrades in terms of qualities of both the animation and the plot.
* HilariousInHindsight: Dellekaj is a red-haired big-nosed chef with a small furry sidekick. [[{{WesternAnimation/Ratatouille}} Sound familiar?]]
* MemeticMutation:
** Rita's dance during the Pig Song.
** Rita herself was a brief ForcedMeme on Website/FourChan.
* {{Moe}}: The titular character and Rita. Both are RidiculouslyCuteCritter's, fun-loving and loveable. Hugo himself being dubbed 'the cutest animal of all' is no surprise.
* MoralEventHorizon: Cupmann finally crosses this right before he tries to capture Hugo near the end of the second movie, when he hires in a pair of violent, aggressive hounds to not only sniff Hugo out, but also to kill Rita due to her "bad influence" over him. All with a gleeful grin on his lips when he explains it to Sensuella. And when she [[EvenEvilHasStandards rightfully protests it]], an annoyed Cupmann immediately fires her.
* NightmareFuel: Cupman going all over the edge in the second film and plainly giving his bloodhounds the order to tear that foxfur apart.
* SeasonalRot: The TV series had much more "out there" plots, compared to ''relatively'' down to earth first two films. The third movie got a little better in that regard, but the writing and pacing arguably was still not on par to the first two.
%%* TearJerker: The ending of the first film.
