Blueprints
Hidden within the game are a bunch of Blueprints, which allow a player to construct different cheats and upgrades. Once found, the Blueprint then must be constructed through Cornelius Robinson's Transmogrifier, which allows cheats to be implemented at any moment in the game.
Health
To get the level 1 health upgrade, you must use the scanner given to you by Lazslo and scan 20 items. For the level 2 upgrade, you must find the side path on the last force field section of the third level with the force field walkways. A chest will contain the blueprint. For level 3, scan 120 items. On level 4, find the chest on the roof of the school. For level 5, complete Uncle Gaston's third challenge following Prometheus.
Energy
You can find the energy level 1 upgrade just after the hotel in the Old Town. Find a manhole nearby and climb one of the tunnels. For level 2, find the chest above the ant spawners. In level 3, find the chest on hive level 2, near the large circle. For level 4, after returning from the science festival, complete Uncle Gaston's second challenge. You can find the disassembler energy upgrade off a path on the way to the Old Town, by the Transaluminum. To get the infinite energy cheat, you must complete the havoc puzzle in the train area. Also, beating Lazslo in chargeball will give you the level 1 charge glove energy upgrade, while scanning 40 items will give you level 2.
Random
The chest behind the refrigerator near the living room will contain the space helmet cheat, while the refrigerator far away from the living room has the dino shirt cheat. The cheat to have all blueprints is in the classroom on the ground floor, near the dining room. Getting good at chargeball also is another way to receive a number of cheats. By beating Art in chargeball, you get the meatball glove cheat. Beating Billie will get you the snowball charge glove cheat, while beating Tallulah will give you the "all chargeball courts" cheat. If you beat everyone at chargeball, you will upgrade all your gadgets to maximum levels.
