* When Muntz was showing off his fossil collection, he made the statement that he "kept the best for [himself]". [[WesternAnimation/TheIncredibles Syndrome]] said the same thing of his gadgetry shortly after confronting Mr. Incredible. That line was probably foreshadowing of Muntz's true nature.

* When they first reach the jungle, Russell has to go to the bathroom and [[NatureTinkling just does it there in the dirt]]. We never see him wash his hands after that, and then just right away he touches and eats the chocolate he gives to Kevin.
** Uh, as someone who has gone camping, there are ways to do one's business without touching a lot of gross stuff. It's not that horrific. And we don't see Russell washing his hands for the entire trek. Not that he could, since there's no running water or soap. I'm sure he's touched worse things than some dirt and his own waste all while feeding bits of that chocolate bar to Kevin.
** Maybe he's got a bottle of hand-sanitizer in his pack.

** More then likely? Neglect. Muntz has a lot of dogs, and Dug most definitely isn't the favorite.

** There are wild animals outside. It likely wasn't pork, but they weren't made of people either.

* Where did Muntz get the ingredients for his dogs to cook dinner for Carl and Russell? Unless the people he killed were...[[ImAHumanitarian oh dear. Well, it's a good thing Russell didn't get to eat that hotdog.]]

* When Russel mentions Phyllis, Carl asks if he calls his mom Phyllis, to which Russel, slightly surprised, replies, "Phyllis isn't my mom." Naturally, he'd be surprised: when they arrived to Paradise Falls, Carl said he wanted to play a game about being quiet and Russel says his ''mom'' likes that game too. He specifically used the word "mom," not Phyllis, so he probably expected Carl to pick up on the fact that they're two different people.

* Earlier in the movie, Carl, in an attempt to get rid of Russel, sends him off on a "snipe hunt", which is normally considered a fake animal used to send people on wild goose chases. Well, according to extra material, Kevin's species is actually a snipe! Seems Russell succeeded in the end after all.
* Well, naturally. The species is undiscovered, and it seems that Muntz was too preoccupied with finding the bird to care about naming it, so since no one but Carl, Russel, and the dogs know about the bird, the default species name is the one that Carl and Russel gave it.

* When they first reach the jungle, Rusell has to go to the bathroom and just does it there in the dirt. We never see him wash his hands after that, and then just right away he touches and eats the chocolate he gives to Kevin.

I'm sure he's touched worse things than some dirt and his own waste all while feeding bits of that chocolate bar to Kevin.

* When they fly back home, Carl and Rusell are wearing aviation hats. Cool eh? Wait.... where did they get the hats from? Yeah, sure take the dead people's hats Carl.

* In the opening sequence, we see Carl and Ellie happily trying to start a family, going so far as to build a nursery for their baby. We then cut to the two in an OB/GYN's office, with Ellie sobbing in her chair and a doctor looking at them sadly. It's likely that Ellie suffered a miscarriage, which is heartbreaking enough--but the fact that the two never try again indicates that Ellie wasn't just suffering from infertility. Rather, she likely ''could'' get pregnant, but had a condition that made all of her pregnancies inherently fatal to either the embryo or herself. She might even have been told that carrying the baby to term would have ''killed her'', and so had to undergo an emergency abortion just to survive.

* When Russel mentions Phyllis, Carl asks if he calls his mom Phyllis, to which Russel, slightly surprised, replies, "Phyllis isn't my mom." Naturally, he'd be surprised: when they arrived to Paradise Falls, Carl said he wanted to play a game about being quiet and Russel says his ''mom'' likes that game too. He specifically used the word "mom," not Phyllis, so he probably expected Carl to pick up on the fact that they're too different people.

* When Russel mentions Phyllis, Carl asks if he calls his mom Phyllis, to which Russel, slightly surprised, replies, "Phyllis is not my mom." Of course he would be surprised, when they arrived to Paradise Falls, Carl said he wanted to play a game about being quiet and Russel says his ''mom'' likes that game too, using the word mom!
* Some have wondered why Carl would turn against Muntz, since he and Ellie were such big fans, and Carl treasured anything related to Ellie's memory. But the both met each other because of their common admiration of Muntz -- that was only the beginning. Their marriage and life was about each other, not Muntz or worship thereof.

** As many birds are wont to do, it could be that Kevin simply takes care of the nest on her own, without her mate. Had Muntz managed to kill her mate, it's unlikely he would still stick around unless he Really needed more than one specimen, alive or dead, as proof. Kevin may have simply been so easy to find and track because her species are long lived and only have eggs every so often. Muntz just got lucky and Kevin just got unlucky.

* So, the main fan theory is that Carl was planning to take his house to Paradise Falls and die peacefully so he could join Ellie. So, what would have happened to Russell if he had gotten to live out that plan?
** He would have sent him home, like he tried to do at first when they got to South America. Carl is not a monster.
** Yeah, but ''how?'' They were in the middle of a South American jungle. There's no sign of civilization anywhere, and Russell's GPS went flying out of the window at the beginning of their journey, there's no way to contact anyone. And I doubt Carl has enough balloons left to make a return trip for Russell.
** That very question is a part of Carl's frustration and uncertainty at that point in the movie, he has no idea, but was willing to try his best to find a solution.
** Had Muntz not flipped out at them, it is likely that Carl would have left Russell to stay with Muntz while he went to Paradise Falls, which would have likely spelt death for Russell.

Well, according to extra material, Kevin's species is actually a snipe! Seems Russel succeeded in the end after all.

* There seems to be only one bird like Kevin. Did Muntz kill Kevin’s mate?

* Carl has a tendency to [[CompanionCube refer to his house and belongings as Ellie]], essentially giving his home his late wife's "personality", so to speak, the way he remembered her. Following that line of thoughts, [[spoiler:Muntz' death is caused by his foot getting snagged by balloons from the house. Ellie saved her husband.]]

!!FridgeLogic
* How did Russell get onto the porch? We never see him during takeoff, but he says he was underneath. It's established very early on that Russell is anything ''but'' athletic. So how'd he get up there?
** Adreneline rush kicked in. People do crazy stuff when their lives are on the line.
* How did Muntz get his hands on the Wilhelm scream sound clip? Wasn't that thing first used in the '50s?
** RuleOfFunny, or maybe he's got really [=WiFi=] and downloaded it.
* If Ellie actually got to go to paradise falls, [[spoiler:Isn't it likely that Muntz, her childhood hero, would have tried to kill her?]]
** No. Ellie is badass. She would've grown into a NeverMessWithGranny type and kicked his ass.
*** Really? Never are we shown that she's a master at martial arts. Just because she has an adventure-spirit it doesn't mean that she's an ActionGirl.
* Dobermans and Rottweilers make sensible guard dogs, and could probably be used for hunting if you trained them well. But English bulldogs, like the one that went along with Alpha and Beta to hunt down Kevin, are far from athletic enough for such jobs and would probably faint from overexertion if they attempted to perform them. Now, this could be overlooked if he were built more like the original bulldog breed (which was probably still around when Muntz went on his expedition), but he's clearly a modern bulldog. What the crap is he doing going hunting in the South American jungles?!
** Perhaps Gamma is supposed to be a bull ''terrier'': a Staffordshire, an American Staffordshire (Amstaff), or a Pit Bull Terrier. (Clearly not a Bull Terrier.) With the Creative Allowance for Animation, he could easily end up looking more like a bulldog. Of course, he could also be a shout-out to Marc Anthony of Looney Toons fame . . .
* Who was taking pictures of Carl and Ellie's intimate moments (her birthday, feeding pigeons and just laying out together)?
** A friend who passed later on, I guess.
** They used a camera with a time-delay shutter, mounted on a tripod. [[Tropers/{{Kalmbach}} This troper]] used that process to photograph his own wedding.
* Carl is eight years old at the start of the film, whereas Muntz is an established explorer, probably around thirty if not older. They meet again when Carl is 78, ''seven decades later''. Muntz is now either close to or over 100 years old, and has been living without any sort of healthcare or modern medicine for all that time. How is he even able to walk by himself, let alone swing a sword or give chase to a man over twenty years his junior across the top of a flying airship?
** The guy made dog collars that allow the wearers to talk, he probably [[{{Steampunk}} steampunked]] himself up some sort of [[Franchise/{{Batman}} Lazarus pit]], Ra's Al Ghul style.
* At several points during the movie Russell is referred to as a "small mailman". These are dogs born and bred in the wilderness, how would they know what a mailman was having presumably never seen one before?
** It's probably something to do with--SQUIRREL!!

* The Methods that the scientific community used to discredit Charles Muntz's Fossils have been themselves discredited over time as grossly inaccurate.
* Kevin's tendency to swallow inedible objects comes off as typical dumb, goofy cartoon bird at first. [[spoiler:Later, you realize that Kevin's actually looking for food to store in ''her'' crop for her chicks, which can't leave the labyrinth. She's testing any new object she finds for edibility, as food would be fairly scarce on the plateau, and learns very quickly which things are edible and which are not.]]
* In the first few minutes when Russell is telling Carl about the Wilderness Explorer badges, he mentions that the ceremony for the promotion to Senior explorer involves all the dads attending. That's why he's so dedicated to getting all the badges: he wants to see his dad. This even makes the ending a bit heartbreaking: [[spoiler: Russell's dad doesn't bother showing up to an event that specifically calls fathers to participate in. It's nice that Russell has Carl in his life at that point, but what a douchebag Russell's father must be!]]
* The first or second time that you watch the movie, you wonder how Carl, obviously an older man, would have survived without running water, electricity, or an unlimited food supply. But then you realize that Carl never wanted to live in Paradise Falls. He wanted to die there.
* At the end, Carl, Russell and Dug are playing a game in which they point out the colours of cars. Dug shouts "grey one!". At first, you think nothing of it. Then you realize: Dogs are colourblind.
** Can a joke based on scientific inaccuracy be labeled as Brilliance? Dogs don't see in black and white, they're red-green colorblind. Dug would be able to see blue, yellow, and violet in addition to greys, white, and black.
** Then it was a red one!
*** Dogs interpret red as yellow. It was more likely actually gray.
** This troper thought he was referring to the Spirit of Adventure when he said that. It was parked right next to them.
** It's actually a different kind of brilliance - Generally when people play these kinds of games in movies they talk about cars like red, blue, or yellow cars. Colorful cars. But the most common colors for cars are [[BoringButPractical white, silver, black, and grey]]. If you assume silver and grey would both be considered 'grey' by the average person then grey cars are the most common car in the world. Of course he'd see a grey one!
* Muntz has never tried using chocolate as a lure for Kevin. Why? Because he has a LOT of dogs and dogs and chocolate don't mix well.
** On a related note, it makes sense that Kevin is fond of chocolate. Living in South America, one of the plants available for Kevin to eat would be cocoa seeds.
** That does raise the question of why he never tried that in all those years.
*** He never went outside. He only sent out seeker dogs to find the bird, and the dogs are trained to place traps as shown with [[spoiler:them able to tie up Russell]]. The only time he's outside is when [[spoiler:he's grabbing the bird and setting the house on fire]]. You'll even notice that he stays in the entrance of his domain before coming out in broad daylight [[spoiler:when he meets Russell and Carl]]. He probably didn't do any other research with the landscape other than to draw it out as a map from his blimp.
* When Carl goes down in the stair lift, the music is la "Habanera" from Carmen, which is about how love is unpredictable. Some of the lyrics are "if you don't love me, I love you, but if I love you, beware". [[spoiler:Carl doesn't like Russell or Dug but ends up loving them both; and he loves Muntz, who will try to kill him.]]
* It's been said that insanity is doing the same thing again and again and expecting a different outcome. Make of that what you will.
* When Russel mentions Phyllis, Carl asks if he calls his mom Phyllis, to which Russel, slightly surprised, replies, "Phyllis is not my mom." Of course he would be surprised, when they arrived to Paradise Falls, Carl said he wanted to play a game about being quiet and Russel says his ''mom'' likes that game too, using the word mom!
