* AdaptationDisplacement: The animated film based on the novel is far more well-known than the original novel.
* DesignatedHero: Vuk; while he is the protagonist, he kills lots of innocent, apparently sapient animals. He also systematically destroys a human's property
* DesignatedVillain: The hunter. He's not particularly evil - he just happens to be a farmer who kills foxes to protect his livestock.
-->"Who count as ''people'' is just a matter of perspective."
* FanonDiscontinuity: [[{{Sequelitis}} The sequel]]. Fans of the original wish that the CGI film never existed.
* MoralEventHorizon: The hunter crosses it when he kills Vuk's entire family early in the movie.
* NightmareFuel: Many characters (even developed ones who had several lines) get not only killed, they are also eaten by our main protagonists. One scene has the title character [[BigEater devouring a duck]] 'till only its head remains. At no point are they drawn realistically -- everybody you see getting mauled is an honest-to-goodness cartoon character. Thankfully explicit {{Gorn}} is avoided, however. Nevertheless, little wonder its second U.S. video release featured most of the death and violence edited out.
* OneSceneWonder: Most of the rather entertaining and memorable animal characters Vuk encounters (such as Szú, the grumpy hedgehog, Unka, the lovesick frog or Nyau, the feral cat) appear in exactly one scene in the movie, then are never even mentioned again. This shows that there's a big forest out there with many colourful inhabitants. Some of these characters are {{Crossover Cameo}}s from István Fekete's other novels, such as Hú the owl, who stars his own book. Special mention needs to go to the two geese, who provide the [[SugarWiki/FunnyMoments funniest scenes]] of the movie.
* {{Sequelitis}}: The second one, made in 2008, is pretty much the complete opposite of the original.
* SpecialEffectsFailure: The sequel was made in 2008, yet the CGI animation was around the level of videogames released at least five years earlier. ''At best.''
* TheyChangedItNowItSucks: One of the many reasons the sequel was disliked is the [[ShiftedToCGI shift to CGI]] and the [[YouDontLookLikeYou change of character designs]].
* TearJerker:
** The moment when Vuk realizes he lost all of his family and cries for them.
** [[spoiler: Karak]]'s death and FinalWords to Vuk.
* ToughActToFollow: This was only to be expected when following up on what is considered one of the greatest animated films of all time, but the sequel was seen as so bad, it was the complete opposite of its predecessor.
* WhatDoYouMeanItsForKids: The movie is definitely a children's cartoon thanks to {{Disneyfication}}, but the novel (by extension most of István Fekete's works) is also considered children's literature in Hungary. Yes. Despite the [[FamilyUnfriendlyViolence violence]], [[FamilyUnfriendlyDeath death]], [[GreyAndGrayMorality moral ambiguity]], heavy themes and [[WhatDoYouMeanItsNotDidactic general lack of sugarcoating]].
* TheWoobie: Vuk. His entire family was killed. [[WoobieDestroyerOfWorlds And this prompts him taking terrible revenge.]]
* {{Woolseyism}}: In the Finnish dub, Vuk's name is an [[FunWithAcronyms acronym]] for "Viisas, urhea kettu" - [[MeaningfulName "Wise, brave fox".]]
