How to distract an Attractor

Brady's class is visiting the Ravenville electrical plant during a field trip, coincidentally on the same day the Attractor, a big magnetic robot, is there to re-charge his magnets. Clumsy Virgil accidentally trips and unplugs an outlet; causing the robot monster to explode, sending his parts to scatter all over Ravenville. Each individual part has a life of its own and is wreaking havoc throughout the city. Can all of Brady's friends put the Attractor back together again?
