Honestly, when you think about Blue Sky Studios, your mind probably jumps straight to that twitchy little saber-toothed squirrel chasing an acorn. But Ice Age: Dawn of the Dinosaurs—or just Ice Age 3 if you’re normal—did something kinda weird and bold back in 2009. It took a group of Pleistocene mammals and dropped them into a tropical "Lost World" underneath the ice. It shouldn't have worked. It felt like a jump-the-shark moment. Yet, the Ice Age 3 characters managed to pull off a story about family dynamics and mid-life crises that actually feels more grounded than the premise suggests.
Ray Romano’s Manny is the anchor. You’ve got this giant, grumpy mammoth who is suddenly terrified because he’s about to be a dad. It’s relatable. It’s human. Even if he weighs eight tons.
The New Dynamic of the Herd
By the third movie, the "Herd" wasn't just a ragtag group of survivors anymore. They were a family. This is where the Ice Age 3 characters really start to show some friction. Manny and Ellie are nesting, which sounds cute until you realize it’s driving everyone else away. Sid, being Sid, feels the void. He’s lonely. He wants what Manny has, but since he’s a clumsy ground sloth, he decides the best way to start a family is to "rescue" three massive eggs he finds in a cavern.

Bad move.
Those eggs hatch into Tyrannosaurus rex hatchlings. It’s a classic Sid moment—blending pure heart with absolute stupidity. John Leguizamo plays Sid with this lisping, frantic energy that makes you realize the character isn't just comic relief; he's the emotional catalyst for the entire plot. If Sid doesn't steal those eggs, nobody goes underground, and nobody meets the breakout star of the franchise.
Enter Buck: The One-Eyed Weasel
If you ask anyone about the best Ice Age 3 characters, they aren’t going to say Manny or Diego. They’re going to say Buck. Voiced by Simon Pegg, Buckminster (Buck for short) is a total chaotic neutral force. He’s a weasel who’s lived in the dinosaur world so long he’s lost his marbles. He wears an eyepatch made from a leaf and carries a knife made from a dino tooth.
He’s brilliant.
Buck represents a shift in the series' tone. While the first two movies felt like survival dramas with jokes, the third one leans into high adventure. Buck is the guide, the "Captain Ahab" of the prehistoric underground, obsessed with a massive white Baryonyx named Rudy. The chemistry between a sane, boring mammoth and a weasel who thinks a broccoli stalk is a phone is where the movie finds its pulse.
Diego and the Mid-Life Crisis
While Sid is busy being a "mom" to T-rexes, Diego is dealing with something way more depressing. He’s losing his edge. He’s a saber-toothed tiger who gets winded chasing a gazelle at the start of the film.
It’s a bit of a bummer, really.
Diego’s arc in this film is about finding his "tiger-ness" again. He thinks the domestic life of the herd has made him soft. It’s a subtle bit of character writing that actually rewards older viewers. You’re watching an animated cat go through a transition that feels suspiciously like a career slump. When he finally steps up to protect the herd in the dinosaur world, it isn't just about fighting; it's about realizing that being part of a pack doesn't make him weak.
Scrat and the Scratte Factor
We have to talk about the squirrel.
In the first two movies, Scrat was a solo act. He was a silent film star trapped in a CGI world. But the Ice Age 3 characters roster expanded to include Scratte (pronounced Scrat-tay), a female saber-toothed flying squirrel who is just as obsessed with the acorn as he is.
Their subplot is basically a 1940s screwball comedy. They dance, they fight, they fall in love, and then they try to murder each other over a nut. It’s a perfect microcosm of the movie’s theme: the conflict between individual desires and the need for companionship. Plus, the tango scene in the "Chasm of Death" is legitimately some of the best physical comedy Blue Sky ever produced.

Why the Dinosaur World Changed Everything
Adding dinosaurs to a franchise called Ice Age sounds like something a marketing executive came up with during a lunch break. But it worked because it forced the Ice Age 3 characters out of their comfort zones.
On the surface, it's just a way to sell toys. I get that. But narratively, it functions as a "Point of No Return." For the first time, the herd isn't just running away from something (like a flood or a glacier). They are going on a rescue mission.
- Manny has to learn he can't control everything.
- Ellie proves she’s the toughest member of the group (while literally in labor).
- Crash and Eddie... well, they’re still the idiots they’ve always been, but even they get some moments of genuine bravery while flying on the back of a Pterosaur.
The stakes felt higher because the environment was actively hostile in a way the tundra never was. Lava, poisonous gas, giant carnivorous plants—it was a gauntlet.
The Technical Evolution of the Characters
If you go back and watch the first Ice Age from 2002, it looks... rough. The fur tech was basic. The movements were stiff. By the time we get to the third film, the animation had leveled up significantly.
The way the Ice Age 3 characters move is much more fluid. Look at the way Manny’s fur reacts to the humidity of the underground jungle versus the dry cold of the surface. Or the way Buck moves with this frantic, kinetic energy that Simon Pegg’s voice acting matches perfectly.
Carlos Saldanha, the director, really pushed the visual scale here. The dinosaur world is vibrant and over-the-top, providing a color palette that makes the characters pop. It’s a far cry from the whites and blues of the earlier films.
Peaches: The Next Generation
The movie ends with the birth of Peaches. It’s a sentimental moment that could have been cheesy, but it works because of the 80 minutes of chaos that preceded it. Peaches represents the culmination of Manny and Ellie's journey. She’s the proof that the herd isn't just a survival pact anymore—it's a legacy.
It also set the stage for the sequels, for better or worse. But in the vacuum of the third film, her arrival feels earned. It’s the payoff for Manny finally letting go of his fear of the future.
Breaking Down the Real Impact
Why do we still care about these characters?
Usually, by the third installment, a franchise is running on fumes. Look at Shrek the Third—it’s widely considered the point where that series lost its way. But Dawn of the Dinosaurs is often cited by fans as their favorite of the series.
It’s because of the balance. You have the high-octane action of Buck and the dinosaurs, but you also have these quiet, character-driven moments. Like when Diego and Manny talk about growing old. Or when Sid realizes he can't actually raise three T-rexes.
It’s a movie about growing up, even if you’re a 10,000-year-old mammoth.

The Ice Age 3 characters didn't just stay the same. They evolved. They got scared. They got weird. And that’s why, nearly two decades later, they still resonate with people who grew up watching them on a loop.
Actionable Takeaways for Fans and Collectors
If you're looking to dive back into the world of these characters, there are a few things you should know. First off, if you’re looking for the best way to watch, the 4K restorations (where available) really show off the fur textures that were groundbreaking at the time.
For those interested in the lore, the "Buck Wild" spin-off on Disney+ is a thing, but it doesn't quite capture the same magic as the original third film, mostly because the original voice cast didn't all return.
- Check out the "Art of Ice Age" books. They give incredible insight into how the character designs for Buck and the dinosaurs were developed.
- Focus on the Simon Pegg performance. If you’re a fan of his work in Shaun of the Dead or Hot Fuzz, you can see his specific brand of frantic humor all over Buck’s dialogue.
- Re-watch for the environmental storytelling. The contrast between the "Blue" world (Ice Age) and the "Green" world (Dino World) is a masterclass in visual directing.
The legacy of the Ice Age 3 characters isn't just in the box office numbers, which were massive by the way—nearly $900 million. It’s in the fact that these characters felt like people. Messy, flawed, funny people. And in the world of animation, that's a harder thing to pull off than it looks.
