Something Fishy

The Fat Controller is looking for engines to run the coastal line. Arthur wishes to, as he's already been there and sees it as his favourite place. Thomas is chosen instead, who complains about the smell of fish. A set of faulty points diverts Thomas onto an old pier and he falls into a tidal pool. Arthur is sent to help, and takes the fish to the Docks just in time. The Fat Controller needs a replacement, so Arthur swiftly volunteers.
