She’s loud. She smells like old compost. She’s constantly trying to outlive her son-in-law out of sheer spite. Honestly, if you grew up watching DreamWorks Animation, Gran from The Croods probably felt like a punchline on legs. But if you actually sit down and look at the survival mechanics of the Croodaceous era, you realize she isn't just comic relief. She’s a tactical genius.
Voiced by the legendary Cloris Leachman—and later June Squibb in the sequels and series—Gran (whose actual name is Maw-Maw or Granny, depending on who’s yelling) represents something deeply human. She is the living embodiment of "survival of the fittest." While Grug is obsessed with rules and staying in the cave, Gran is the one who has already seen it all and lived to tell the tale. She’s old. In the Stone Age, being old is a superpower.
Think about it.
In a world where a "Macawnivore" can snap your neck in three seconds, reaching the age of 80 (or however old she is) is a statistical miracle. She didn't get there by accident.
The Evolution of Gran from The Croods: From Joke to MVP
When we first meet Gran from The Croods in the 2013 film, she’s basically a thorn in Grug’s side. The running gag is simple: Grug waits for her to die so there’s one less mouth to feed, and she refuses to do it. It’s dark. It’s funny. But it also establishes her primary trait—indestructibility.
She has a tail. Did you notice that? It’s never fully explained in a scientific sense, but it implies that she’s a bridge between the more primitive hominids and the "modern" Croods. While the rest of the family is trying to figure out how to walk upright and use fire, Gran is tapping into primal instincts that the others have started to lose. She’s scrappy. She’s mean. She uses her cane as a weapon, a tool, and a stabilizer.
In The Croods: A New Age, we see a different side of her. She isn’t just a cranky elder; she’s a leader. When the "Punch Monkeys" and the "Spiny Mandrills" become a threat, it’s Gran who assembles the "Thunder Sisters." This wasn't just a fun "girl power" moment for the plot. It was a callback to her past. She mentions that the Thunder Sisters were a real group she belonged to. This tells us she had a life, a crew, and a set of combat skills long before Grug was even a thought in Ugga's head.

Why Gran’s Survival Instincts Matter
Most people think Grug is the protector. He’s the muscle. But muscle gets you killed if you don’t have the intuition to back it up. Gran from The Croods thrives on intuition. She understands the environment better than anyone because she’s lived through more disasters.
Look at her relationship with Douglas, the Croopup. She treats him like a loyal soldier. She understands the symbiotic relationship between humans and animals better than Guy does, even if Guy is the "inventor." While Guy is trying to solve problems with logic, Gran solves them with sheer, unadulterated grit.
- Adaptability: She doesn't complain about the "new" world the way Grug does. She just finds a way to dominate it.
- Physicality: Despite her hunched posture, her agility is terrifying.
- Psychological Warfare: She knows exactly how to get under Grug’s skin, which keeps him sharp. You could argue she’s training him.
The Cloris Leachman Legacy
You can’t talk about this character without talking about Cloris Leachman. She brought a rasp and a frantic energy that made Gran feel unpredictable. When Leachman passed away, there was a genuine concern about whether the character would lose her edge. June Squibb stepped in for the later iterations, like The Croods: Family Tree, and managed to keep that "I’ve buried three husbands and I’ll bury you too" energy alive.
It’s that voice work that makes the character work. If Gran was just a silent old lady, she’d be boring. But she’s a constant noise machine. She’s a reminder that life—even in the brutal prehistoric era—is meant to be lived loudly.
What Fans Get Wrong About the Thunder Sisters
There is a huge misconception that the Thunder Sisters was just a name Gran made up on the fly to make Eep and the others feel cool. If you watch the sequence closely in the second film, her combat moves are practiced. They are choreographed.
This suggests that in the world of Gran from The Croods, there was once a matriarchal society or at least a highly organized group of female hunters. This adds a layer of world-building that the movies only hint at. It suggests that the "Crood" way of living in a cave wasn't the only way people survived. Gran came from a tradition of warriors. When she puts on that bone armor, she isn't playing dress-up. She’s returning to form.
The "Death" Gag and Social Commentary
The ongoing joke about Grug checking to see if she’s dead is a bit grim for a kids' movie, right? But it’s actually a very real look at resource scarcity. In the Paleolithic era, the elderly were often seen as a burden because they couldn't hunt.
Gran flips this trope. She contributes more than she consumes. Whether it's through her knowledge of plants, her ability to track predators, or just her sheer refusal to let the environment win, she proves that age is an asset. She’s the keeper of the "old ways" that actually work. While Grug is obsessed with "the cave," Gran is the one who reminds the family that they are part of a wilder, more dangerous world that requires them to be fierce.
Key Takeaways for Croods Fans
If you're looking to appreciate the character more, pay attention to her eyes in the background of scenes. She’s rarely surprised. When a giant beast jumps out, she usually looks annoyed rather than scared. That’s the mark of a survivor.
She also has a weirdly high pain tolerance. She gets thrown, crushed, and bitten, and she usually just pops back up with a snarky comment. This isn't just "cartoon logic." It's a character trait. She is the toughest member of the family, hands down.
How to Lean into the "Gran" Philosophy
You don't have to live in a cave to learn from Gran from The Croods. Her approach to life is basically "Resilience at all costs."
- Stop overthinking the change. When the world literally ended in the first movie, Gran didn't have a mid-life crisis. She grabbed her cane and started walking.
- Keep your circle tight but your skills sharper. The Thunder Sisters showed that collaboration is key, but individual competence is non-negotiable.
- Spite is a powerful motivator. Sometimes, staying alive just to annoy your enemies (or your son-in-law) is enough to keep you going through the toughest winters.
Final Thoughts on the Prehistoric Matriarch
Gran is the anchor of the family's history. Without her, the Croods are just a group of people wandering in the dark. With her, they have a link to a past that was even crazier than their present. She isn't just a "funny grandma." She’s the reason the bloodline survived long enough for Eep to meet Guy.
Next time you watch the films, don't just laugh when she bites Grug. Look at how she navigates the terrain. Look at how she handles the animals. She’s a masterclass in prehistoric survival.
To truly understand the depth of the Croods universe, you have to look past the slapstick. Start by re-watching the Thunder Sisters sequence in The Croods: A New Age and note the specific tactical callouts Gran makes. It reveals a history of tribal warfare and survival techniques that predate Grug’s "protection" era.
