Once upon a time, there was a big, red robot who liked to eat metal. His name was Robby. Robby lived in a small house with his best friend, a little girl named Lily. They played and laughed together every day.
One day, Robby found a big pile of metal in the yard. He was very happy and started to eat it. But, some of the metal was spoiled. Robby didn't know this, and he started to feel sick. Lily saw that Robby was not feeling well and she was very worried.
Lily didn't know what to do, so she called her friend, Dr. Bear. Dr. Bear was a smart bear who knew how to make robots feel better. Dr. Bear came to help Robby, and he found out that the spoiled metal was making Robby sick. Dr. Bear gave Robby some good metal to eat, and soon, Robby felt better. Robby and Lily were so happy, and they thanked Dr. Bear for his help. From that day on, Robby only ate good metal, and they all lived happily ever after.
