Magnetic Mayhem (ペタンコ こうじょうアリーナ lit. Squashing Factory Arena in Japanese) is the fourth and final battle arena in Crash Nitro Kart and is found in Teknee. The music here is the same as the one used for the race track Electron Avenue.
Number of Crystals: 20
Time limit: 160 seconds
The level is set underneath Electron Avenue, and it is quite warm and toasty. It is relatively easy despite the nitro crates, due to the fact that the Crystals are almost in completly one area. The level has some machinery, but also is very quiet in ways and is a peaceful resting place for robots and racers.
