Retro gaming fans usually have a love-hate relationship with THQ. During the early 2000s, the publisher was basically a factory for Nickelodeon tie-ins. Some were gems. Others? Total shovelware. But Jimmy Neutron Attack of the Twonkies occupies this strange, chaotic middle ground that feels like a fever dream. If you grew up with a PlayStation 2, GameCube, or Xbox, you probably remember the cover art: a terrified boy genius being swarmed by what looked like fluffy, murderous Furby rejects.
It wasn't just a quick cash-in.
The game actually served as a massive crossover event with the TV show. Specifically, it tied into the "Attack of the Twonkies" special that aired in 2005. Most licensed games from that era were just bad platformers that loosely followed a movie plot. This one? It tried to be a gadget-based survival horror game for kids.
The Weird Mechanics of Jimmy Neutron Attack of the Twonkies
Think about the premise for a second. Jimmy brings a "cute" alien species back from a comet. They seem harmless. Then they hear music. Suddenly, these cuddly puffballs transform into hulking, grotesque monsters that look like they crawled out of a John Carpenter movie.
THQ and developer THQ Studio Australia—which later became Blue Tongue Entertainment—didn't just make a jumping game. They leaned hard into Jimmy’s "Boy Genius" persona. You weren't just punching enemies. You were collecting literal trash to build inventions. It’s a mechanic that feels surprisingly modern, almost like a precursor to the crafting craze we see in games today.
The Gizmo Resonator was the heart of the experience. You’d find a vacuum handle, a tin can, and some duct tape, and suddenly you had a weapon. It was clunky. Honestly, the controls were a bit of a nightmare sometimes. But it felt authentic to the show’s spirit. You felt like a kid who was way out of his depth, using science to fix a problem he definitely caused himself.
A Soundtrack That Actually Matters
Music is usually just background noise in kids' games. In Jimmy Neutron Attack of the Twonkies, it’s a core gameplay mechanic. Since music triggers the Twonky transformation, the game uses audio to build genuine tension.
When you hear that upbeat, jaunty tune starting to warp, you know you're in trouble. It’s a clever way to use the source material's lore. Most developers would have just ignored the "music makes them evil" rule for the sake of an easier development cycle. Instead, they leaned into it. You had to use a "Sheen’s Costume" mechanic or specific sound-based gadgets to manipulate the creatures. It was weirdly tactical for a game aimed at ten-year-olds.

Why the Graphics Held Up (Mostly)
Let's be real. 2004-era licensed games usually look like blurry soup. But the art style of Jimmy Neutron: Boy Genius actually translated well to the PS2 and GameCube hardware. Because the show was already CGI, the game didn't have to "approximate" a 2D look.
Retroactive reviews often point out that Retroville feels surprisingly alive. You could explore the school, the park, and Jimmy’s lab. It wasn't an open world—not by a long shot—but the hub-world design gave it a sense of scale. The character models for Carl and Sheen looked exactly like their TV counterparts, which was a huge deal back then.
However, the frame rate? Yikes.
If too many Twonkies were on screen, the PS2 version specifically would chug like an old lawnmower. It’s one of those technical flaws that reminds you this was a "B-tier" project. Yet, the ambition was there. You could see the developers trying to push the hardware to handle dynamic object physics and multiple enemy AI routines simultaneously.
The Difficulty Spike Nobody Expected
Kinda surprisingly, this game is tough.
Most Nicktoons games are a breeze. You breeze through SpongeBob SquarePants: Battle for Bikini Bottom with a smile on your face. But Jimmy Neutron Attack of the Twonkies has some genuinely frustrating sections. The boss fights against the massive, evolved Twonkies required actual pattern recognition and quick switching between gadgets.
If you didn't have the right invention equipped, you were toast.

There was also the "Twonky Meter." If you let too many aliens escape or evolve, it was game over. This added a layer of stress that felt more like Pikmin or Dead Rising than a standard Nickelodeon platformer. It demanded a level of resource management that most kids probably weren't prepared for in 2004.
Comparing the Console and Handheld Versions
Most people forget there was a Game Boy Advance version. It was a completely different beast. Developed by Tantalus Media, the GBA port was an isometric action game.
It was... okay.
But the console version is the one people talk about. The GBA version felt like every other handheld port of the era: limited, repetitive, and a bit hollow. The console version, despite its glitches, felt like an expansion of the Jimmy Neutron universe. It felt like an "event."
Fact-Checking the Legacy
People often confuse this game with Jimmy Neutron: Boy Genius (the 2001 movie tie-in) or Jet Fusion.
- Boy Genius (2001): Very basic, mostly mini-games and racing.
- Jet Fusion (2003): More combat-focused, tied to the TV special.
- Attack of the Twonkies (2004): The most polished of the three, focusing on the crafting and "survival" aspect.
It's easy to see why they blend together in people's memories. They all used similar assets and the same voice cast. Getting Debi Derryberry (Jimmy) and Rob Paulsen (Carl) to do the voice work for the game was a huge win for authenticity. It didn't feel like a knock-off; it felt like a lost episode of the show.
Why This Game Deserves More Respect Today
We talk a lot about the "Golden Age" of licensed games. We usually mention Spider-Man 2 or The Simpsons Hit & Run. Jimmy Neutron Attack of the Twonkies rarely makes the list.

That’s a shame.
It tried to do something different with the "collect-a-thon" genre by adding a crafting system and environmental puzzles based on physics. It wasn't perfect. The camera was often your worst enemy, and some of the stealth sections were frankly broken. But the heart was there.
It captured the specific brand of "early 2000s weirdness" that defined Nickelodeon. It was gross, it was chaotic, and it was surprisingly smart.
How to Play It in 2026
If you're looking to revisit this, you have a few options. Physical copies for the PlayStation 2 and GameCube have actually started to climb in price slightly as "hidden gem" collectors snatch them up.
- Check Local Retro Shops: You can usually find the Xbox or PS2 versions for under $30, though the GameCube version is pricier because Nintendo collectors are intense.
- Emulation: If you have the original disc, using an emulator like PCSX2 or Dolphin allows you to upscale the resolution to 4K. It makes those 2004 textures look remarkably crisp.
- The Xbox "Problem": While many OG Xbox games are backward compatible on Series X, this isn't one of them. You’ll need original hardware for the best experience.
Final Thoughts on the Twonky Invasion
The game wasn't a masterpiece. It was a flawed, ambitious, and slightly terrifying experiment in licensed gaming. It proved that you could take a kids' property and give it complex mechanics like inventory management and environmental audio triggers.
If you want a trip down memory lane that feels a bit more "stressful" than your average platformer, track down a copy. Just remember to keep the music down. You don't want the Twonkies to hear you.
To get the most out of a replay, focus on the "Invention Lab" early on. Mastering the crafting shortcuts saves you hours of backtracking through Retroville's streets. Also, keep an eye out for the hidden Goddard upgrades; they are the only way to survive the late-game difficulty spikes without losing your mind.
