Cheats for Jimmy Neutron: Attack of the Twonkies

Based on the popular cartoon, "Jimmy Neutron: Attack of the Twonkies" for the Nintendo GameCube or PlayStation 2 lets you play as the boy genius himself, Jimmy Neutron, as he tries to make up for accidentally releasing alien creatures on Earth. Jimmy must create numerous inventions to help him capture the pesky Twonkies and return them to their home planet. Knowing a few cheat codes and tricks can help Jimmy accomplish his mission.

Action Replay
- The game does not include any official cheat codes. However, using an external cheating device like Action Replay does grant access to some cheats. If using Action Replay, enter "W5EV-HZXK-XAFHY VWU3-6CQH-3CGP3" to get extra genius points. The code "V03X-XD7F-M0J35 0T60-DCQ0-4XNDK H66D-03WU-J7B9D" provides infinite invention juice. To get infinite rocket shield, enter the code "8WND-1GGC-HH5KR UZ9T-W4EN-YA345."
Unlockables
- To unlock special bonus challenges, successfully complete the game's Retroland level. If you beat the entire game, you unlock a bonus jetpack race level. The game also prevents you from making some inventions until you accomplish certain tasks. If you're able to make an invention, a box appears in the top right corner of the screen to indicate the invention has been unlocked.
Control Panel Puzzle
- In Episode 2, you must navigate through a meteor storm to reach a space station. Find the magnet and combine it with your sneakers to create Attracto Sneakers, which let you walk around freely. Once inside the space station door, you need to solve a control panel puzzle by pushing a series of buttons in the correct sequence. The puzzle's solution requires you to push the blue button three times, the green button three times and then the red button three times.
Frozen Lake Boss
- In Episode 10, combine the trumpet, the slingshot, the red mineral and the hockey puck to invent the Energy Puck Launcher. Before facing the level's boss, get the cotton candy and combine it with your sneakers to make Sticky Sneakers, which prevent you from sliding around the ice surface upon which the battle takes place. The Frozen Lake Monster claps his hands and stomps his feet, causing ice spikes to attack you. Use your Energy Puck Launcher to fire pucks up a ramp and sail them over the monster's protective ice barrier. You can also shoot pucks into the barrier itself to create openings for subsequent attacks. Once the barrier falls, you can shoot pucks directly into the monster's feet, inflicting serious damage. Follow the same plan until the monster falls.
