Fridge Brilliance
- A reason for Scrat to never get to devour his acorn and being punished by the combined forces of nature and physics: Scrat was never supposed to eat acorns in the first place! The newly discovered prehistoric creature, that was most similar to him, was a strict carnivore.
- If you pay attention, it seems that most of the movies contain a reference to the next movie in the series:
- In the first movie, during the ice cave scene, we see a number of objects frozen in ice, all of which seem in retrospect to be call-forwards to the various sequels. There's a vicious-looking fish (the second movie), a dinosaur (the third movie), an ape-like creature (the fourth movie) and an alien spaceship (the fifth movie).
- At the end of the original Ice Age Sid says something about global warming. Cue Ice Age: The Meltdown. One of the sabers also remarks that mammoths never travel alone, foreshadowing The Reveal at the end of the first sequel.
- In Ice Age: The Meltdown, when Manny says mammoths can't go extinct because they're the biggest things on earth, someone counters “well what about the dinosaurs?” Cue Ice Age Dawn of the Dinosaurs.
- Ellie takes a quick little jab at Manny in Dawn Of the Dinosaurs about not being able to relax about the baby, and wonders "how he'd deal with the teenage years". Cue the next movie, where she's a teenager and Manny is not dealing with it in the best way.
- In Ice Age: Continental Drift, after Sid's family leaves, Diego lies to Sid that they were wiped out by an asteroid. Cue Collision Course, where the characters have to stop an asteroid that's going to wipe them out.
- Manny displays serious overprotective tendencies toward Ellie and Peaches in particular. It's understandable, considering what happened to his last family.
- Instances of Sid being a Jerkass to Manny and Diego could actually be him biting back at them for them being similarly mean to him.
- Manny is a firm believer in loyalty. That's why he keeps his promise to help Sid return the baby even though he couldn't stand him. He also tells Sid that he should be loyal to his mate or in his case grateful and why Manny goes berserk over being betrayed. Also why in the next film he refuses to be with Ellie because he wants to be loyal to his first wife. Ditto in the third film where he becomes upset at Diego for deciding to leave the herd. Comes to a head in the fourth where he puts all his mind into reuniting with his family after getting separated by the titular continental drift. This is summed up by Ellie when she's comforting Peaches that Manny will come back for them:Ellie: Your father is the toughest, most stubborn mammoth I've ever met! He'll come back for us. That's a promise.
Fridge Horror
- Sid's family abandons him, with no idea that he'll survive the week. Knowing Sid, it's very possible that they suspected that he wouldn't survive, and they left him anyway. And then, they did the same to Granny, all because they thought the two were "screw-ups." No wonder Sid is so desperate for affection.
- Diego's (and Shira's) diet. It's established that most of the animals are sentient, and he's friends with quite a few of them. But, as a carnivore, he has to eat something. There are some options of hunting animals that are non-sentient in the Ice Age universe, such as fish, reptiles and amphibians, as well as the option of scavenging carcasses of animals that died during one of the natural hazards that happened throughout the movies. However, Diego is shown hunting a deer (but not succeeding) in the third movie and threatens to eat Crash and Eddie in the second movie, which could mean that any other prey who gets on Diego's bad side isn't going to be so lucky, which itself is another Fridge Horror. Add to it that Manny makes it perfectly clear he's fine with carnivores doing their thing when they're hungry. It's only animals who kill for pleasure he doesn't like. Which might mean that he'd probably do nothing to help anyone unfortunate enough to wind up on Diego and Shira's menu as long it it's not himself, Ellie, Peaches, possibly Crash and Eddie, and maybe Sid. Either that, or Diego simply does his hunting far enough away from the rest of the herd that they wouldn't be bothered by it or try to interfere.
