Bobby (The End of the Rainbow)

In 2009, Bobby discovered a broken Filbik colour coder in a park. After taking it home, the colour coder released a rainbow which would colour-code and catalogue any living being that touched it. When the Tenth Doctor followed the rainbow into Bobby's bedroom, Bobby colour-coded herself so that she would be transported to the nearby Filbik storage ship with the Doctor. There she explained the mishap to the Filbik, who politely agreed to return all of the samples taken by accident. She was transported back to Earth when the Doctor took over the storage ship's control room in order to return all of the collected samples. (PROSE: The End of the Rainbow)
