Bobby is a salvage barge, who, like all the other barges, is a good friend of the tugs and always quiet. He is very encouraging and lifted George's spirits when he didn't win an award. For a while, he was part of the Salvage Team with Theodore, Rebecca and Northumberland. They all worked together to find an old rusty ship's anchor at the bottom of the ocean.
