Fan Casting The Fillbots in The Dazzles

The Fillbots are manufactured at the various Robot Factories, and are described as "delicate, precise machines" in the Robot Manual. They have a very highly advanced artificial intelligence, and by the time they reach the fueling zone at the end of the assembly line, they're already conscious and aware of the other robots around them. They might get offended if they notice another receiving more fuel than them, and are known to explode if given too much fuel. When they receive just the right amount of fuel, they take off into the sky, happy as can be.
