If you grew up in the late nineties, you probably have a specific sound embedded in your brain. It’s a high-pitched, unintelligible gibberish punctuated by the words "You fired!" followed by a chaotic tumble. I’m talking, of course, about Tuck and Roll. These two are the A Bug's Life rollie pollies, and honestly, they might be the most underrated comedic duo in Pixar’s entire filmography. While Flik was busy being the misunderstood inventor and Hopper was busy giving us nightmares, these two pill bugs were basically the heartbeat of the P.T. Flea circus.
They’re weird. They’re round. They don’t speak English.
Actually, they don't speak any recognizable human language at all. That was a very deliberate choice by the creators at Pixar. Most people assume they’re speaking some sort of mock-Hungarian or perhaps just random nonsense, and they aren't far off. But it’s that lack of traditional dialogue that makes them so effective as physical comedians. You don't need to know what they're saying to understand that they are constantly bickering, usually about whose fault it is that they just crashed into a wall.
What Kind of Bugs Are They, Really?
In the movie, everyone calls them rollie pollies. In the real world, scientists call them Armadillidium vulgare. They aren't actually insects. They’re terrestrial isopods. Basically, they are land-dwelling crustaceans. If you look at them closely in the film, the animators did a decent job of capturing that segmented, armored look, though they obviously gave them big, expressive eyes and eyebrows to help with the acting.
Interestingly, the "rolling" mechanic is their primary defense in nature. When a pill bug feels threatened, it curls into a ball to protect its soft underbelly. In A Bug's Life, Pixar turned this biological defense mechanism into a circus act. Tuck and Roll spend most of their screen time as living cannonballs. It's a classic example of character design following function. They are built for impact.
Think about the physics here. When they lock together and spin, they become a single unit of kinetic energy. It’s a recurring theme in the movie—the idea of "the colony" or "the group" being stronger than the individual. Even though Tuck and Roll are just two goofy guys, they literally cannot perform their best tricks without each other. They are the ultimate team players, even if they spend half their time hitting each other in the face.
The Voices Behind the Gibberish
You might think that because they don't speak English, Pixar just used some stock sound effects or random office staff to record their lines. Nope. They actually hired Michael McShane. He’s a veteran improv actor you might recognize from Whose Line Is It Anyway? or as Friar Tuck in Robin Hood: Prince of Thieves.
McShane provided the voices for both characters.
The genius of his performance is in the inflection. He managed to convey excitement, anger, confusion, and triumph using sounds that aren't words. It’s a masterclass in vocal acting. If you watch the outtakes—which were a huge part of the marketing for A Bug's Life back in 1998—you can see how much fun they had with this. There’s a specific blooper where they’re arguing in their gibberish language and one of them breaks character and starts laughing. It feels human, despite them being blue, segmented crustaceans.
The Circus Dynamics
Tuck and Roll aren't just there for gags; they represent the "struggling artist" trope within P.T. Flea’s circus.
- They are clearly the most talented acrobats.
- They are the most loyal to the troupe.
- They are also the ones most frequently exploited by P.T. Flea’s greed.
When the "Flaming Wall of Death" act goes wrong (and it always goes wrong), it’s Tuck and Roll who take the brunt of the fire and the impact. Yet, they always bounce back. Literally. Their resilience is kind of an unsung theme of the movie. While Flik is dealing with an existential crisis about his place in the world, the rollie pollies are just happy to be included, as long as they get to bop someone on the head occasionally.
Why We Still Care Decades Later
Why are we still talking about the A Bug's Life rollie pollies in 2026? It’s because Pixar hasn’t really made characters like them since. Modern animation tends to rely heavily on witty, fast-paced dialogue and pop-culture references. Tuck and Roll are a throwback to the silent film era. They’re like Buster Keaton or Charlie Chaplin but in bug form.
They don't need a "hero's journey." They don't need a tragic backstory. They are just pure, distilled personality.
There is also the nostalgia factor. For a lot of Millennials and Gen Z, A Bug's Life was the first time we saw 3D animation really nail character "squash and stretch." When Tuck and Roll hit a surface, they flatten slightly before springing back. It’s satisfying to watch. It’s visual ASMR from a time before that was even a term.

Realism vs. Animation
If we're being honest, real pill bugs are kind of boring. They live under damp logs and eat decaying plant matter. They don't do backflips. They don't have eyebrows. They definitely don't have Hungarian-ish accents.
But that’s the magic of what Pixar did in 1998. They took one of the most common, overlooked "bugs" in the backyard and turned them into international superstars. It changed how a generation of kids looked at the dirt. Suddenly, the little grey thing under the rock wasn't just a pest; it was a potential circus performer.
The Impact on the "Bug Wars"
It’s impossible to talk about these guys without mentioning the 1998 rivalry between Pixar’s A Bug's Life and DreamWorks’ Antz. While Antz went for a more mature, Woody Allen-esque vibe with its characters, Pixar leaned into the whimsical and the colorful. Tuck and Roll were the secret weapon in that fight. They appealed to kids because they were funny and round, but they appealed to adults because their comedic timing was impeccable.
Antz didn't have anyone like Tuck and Roll. It had Sylvester Stallone as an ant soldier, which was cool, sure. But it didn't have the chaotic energy of two isopods who only know three words of English and one of them is "You’re fired."
How to Spot the Differences
If you’re watching the movie again—maybe for the tenth time or the first time with your own kids—you might wonder how to tell Tuck and Roll apart. It’s tricky. They are identical twins.
- Tuck is usually the one on the left in the posters.
- Roll is usually the one on the right.
- Honestly? It doesn't really matter. Their whole identity is being a pair.
They are a singular chaotic force. In the final battle against the grasshoppers, they aren't fighting for "the cause" or for "the revolution" in the same way the ants are. They are fighting because their friends are in trouble and because they finally have a chance to use their circus skills for something bigger than a flea’s paycheck.
Actionable Insights for Fans and Collectors
If you’re looking to dive deeper into the world of these iconic isopods, here’s how you can actually engage with the fandom or the science today:
- Watch the "Outtakes": If you have Disney+, don't just stop when the credits roll. The fake bloopers created for the theatrical re-release and home video are where Tuck and Roll truly shine. It shows the technical skill required to "animate" a mistake.
- Look for the 1998 Mattel Figures: If you're into vintage toys, the original Tuck and Roll "Flip 'n' Roll" figures are surprisingly well-made. They actually lock together just like in the movie. They are becoming increasingly rare in good condition.
- Observe Real Isopods: Next time you’re in the garden, find a damp spot and look for a pill bug. Observe how it moves. You’ll notice the segmented shell is exactly what the Pixar artists used as a reference for the characters' armor. It’s a great way to introduce kids to entomology through the lens of a movie they love.
- Check out the Pixar Archives: Occasionally, the "Art of" books for early Pixar films go back into print. The character sketches for the rollie pollies show how they evolved from realistic-looking crustaceans to the expressive, blue-tinted clowns we see on screen.
Tuck and Roll prove that you don't need a lot of words to leave a big impression. They are the comedic glue of A Bug's Life, and their legacy as the greatest isopods in cinema history is pretty much secure.
