Bobby is a green 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.
There are a few episodes where Bobby does not have his crane arm on his deck.
Bobby's hull and crane would later be used for Bayswater, while his cabin was used for Brunswick.
In the Danish dub, Bobby is not named and simply referred to as 'The Pallet Barge'.
In the Finnish version of Theodore and the Oil Rig, Bobby was called Pasi, though he wasn't named in Theodore's Whistle and George's Ghost for unknown reasons.
