* AdaptationDisplacement: Apparently it was a book first.
* AllAnimationIsDisney: And in an interesting twist, it is also sometimes mistaken for a Creator/DonBluth movie, which of course it also isn't (instead, it was produced by HannaBarbera, out of all companies.) Though its posters and trailers which proudly proclaimed "from the creator of WesternAnimation/AnAmericanTail" would have you think otherwise (they mean David Kirschner, not Bluth).
* BigLippedAlligatorMoment: The part where the group comes across the flock of birds, and has to save Bosworth. This section really doesn't contribute anything to the story, except to introduce the concept of "the Yellow Dragons."
** The scene was probably inserted just to give Ben Vereen his OneSceneWonder.
* CrowningMusicOfAwesome: [[http://www.youtube.com/watch?v=Qs1rTn81ODQ "Once Upon a Time With Me"]]. [[SandInMyEyes Just...that song.]]
** I'm sorry, but it's got nothing on [[http://www.youtube.com/watch?v=PuPiAA3onVI "Please Wake Up."]]
** [[http://www.youtube.com/watch?v=MMCgW0ZMqGQ "The Forest"]] isn't too shabby either. The soundtrack as a whole is one of Music/JamesHorner's most overlooked and underrated film scores.
* CultClassic
* EnsembleDarkHorse: Phineas. It helps that he was voiced by Ben Vereen.
** Also Edgar, who was the only character to get a limited edition stuffed animal version made.
* FridgeLogic: Waggs is such a JerkAss because...well, imagine growing up with a name like ''Waggs''.
* InferredHolocaust: Though two deaths [[spoiler: (Michelle's parents)]] are shown onscreen, the gas leak would have probably killed many more cute furry forest creatures than that...
* NightmareFuel: The music becomes a lot scarier after [[spoiler: the gas leak from the truck spreads into the forest]], but this is taken UpToEleven when Michelle runs off and eventually makes it into her house [[spoiler: which is full of poisonous gas]] causing everyone to panic and Abigail runs in after her. Now keep in mind that Abigail is a ''young girl'' going down an underground passage [[spoiler: full of deadly gas]] and when she finally makes it to the bottom, what's the first thing she sees? [[spoiler: The bodies of Michelle's dead parents.]] This is all while trying to reach and move her younger friend's body to safety, [[spoiler: because she had been poisoned by the gas and was now unconscious and close to death herself as a result.]] This is why Abigail's bravery is so highly regarded by the others. This is a pretty intense scene for a G-Rated movie.
** The scene with the owl counts for this all too well.
*** Abigail's [[spoiler: surprisingly sharp teeth.]]
** And the scene where [[spoiler: the humans return to clean up the mess, and Edgar gets caught in a trap. Luckily, it stops being scary when one of the humans frees Edgar and proves that not all HumansAreBastards]].
* OneSceneWonder: Phineas, the pastor of the bird choir, Willy and Waggs from the meadow.
* {{Padding}}: The scene with the wrens sticks out the most.
* SoBadItsGood: From Michael Crawford's LargeHam acting to yet another GreenAesop.
* TastesLikeDiabetes: Michelle is way too cute. You cannot resist.
* ValuesResonance: After things like the oil spill in the Gulf of Mexico, this film and its {{aesop}} are still particularly relevant.
** It stands alone as one of the unique western animated movies that ''aren't'' "[[DisneyPrincess princess]] [[{{Anastasia}} movies]]" with a female central protagonist, something much desired for nowadays and even more rare when it was released.
* TheWoobie: Michelle, definitely.
** Cornelius certainly qualifies, especially given that [[spoiler: now Michelle is all the family he has left in the world, and]] he can only sit there helplessly as she's slowly slipping away.
** Also Abigail, when she starts feeling bad about herself for thoughtlessly leading the furlings into danger.
** Edgar also has his moments of this.
** Also Bosworth, the young wren trapped in the mud that the furlings save.
* UnfortunateImplications: Along with part of MightyWhitey, apparently the birds who know the land well and have wings cannot save Bosworth who is very ''slowly'' sinking, they just give up and have the funeral. But the kids who know nothing of the land and lack that JiveTurkey accent easily get him out.
