Once upon a time, in a land of whirring gears and flashing lights, lived three robot brothers: Rusty, Bolt, and Spark. They were all built by a brilliant inventor, Professor Whizbang, who had given them each a unique ability. Rusty, the eldest, was strong and sturdy, built with tough metal that could withstand any blow. Bolt, the middle brother, was quick and agile, with lightning-fast reflexes and a powerful electric charge. Spark, the youngest, was clever and resourceful, with a mind that could solve any puzzle.

One day, Professor Whizbang announced that he was leaving on a grand adventure to explore the far reaches of the galaxy. He told his robot sons, "I'm leaving you in charge of the workshop. Be good, work hard, and most importantly, stay safe!" The brothers promised to be responsible and looked forward to their time alone in the workshop.

But their peaceful days were soon interrupted. A monstrous dragon, with scales as green as emeralds and eyes like burning coals, appeared on the horizon. He had heard rumors of the workshop's amazing inventions and was determined to claim them for himself. The dragon roared, "I'm hungry! And I want all your shiny bits!"

Rusty, ever the brave one, stepped forward. "We won't let you take our inventions!" he declared. Bolt, ever the quick one, zipped around the dragon, trying to distract him with his electric sparks. Spark, ever the clever one, started to think of a plan.

Rusty decided to build a house out of the strongest metal he could find. He hammered and welded, his sparks flying in the air, until he had created a sturdy metal house. The dragon roared and slammed into the house, but it held strong. Rusty had built a house that could withstand the dragon's fire! "Ha!" he shouted, "You can't get me!"

Bolt, seeing Rusty's success, decided to build a house out of the fastest-moving metal he could find. He used his electric powers to weld the metal together, creating a house that could spin and dodge any attack. The dragon roared and swooped down, but the house spun so fast that the dragon couldn't hit it. "You can't catch me!" Bolt shouted, as he zipped around the dragon.

Spark, watching his brothers' efforts, realized that he needed a different approach. He decided to build a house out of a special kind of clear plastic that could bend and twist like rubber. He used his clever mind to design a house that could trap the dragon's fire. The dragon roared and breathed fire, but the fire simply bounced off the plastic, trapping itself inside the house. "Gotcha!" Spark shouted, as he watched the dragon struggle.

The dragon, trapped in his own fire, started to panic. He flapped his wings and roared, but he couldn't escape the plastic house. Just then, Spark had an idea. He used his soldering iron to create a small opening in the house. "Come on, dragon!" he called out. "I've got something for you!"

The dragon, desperate to escape the heat, rushed out of the house. Spark had created a special kind of energy drink that could quench the dragon's thirst for fire. He offered the drink to the dragon, who eagerly gulped it down. The dragon, feeling refreshed and no longer hungry, realized that he had been wrong to try to take the robots' inventions. "Thank you!" he said, "I was just hungry, I didn't mean to cause any trouble."

The three robot brothers, seeing the dragon's change of heart, forgave him. They all learned a valuable lesson that day: even the most fearsome creatures can be overcome with kindness and understanding. And so, the three little robots continued to live happily ever after in their workshop, creating amazing inventions and making new friends, even if they were a little bit fire-breathing.
