Tuneful Toots is the ninth episode of the ninth season.
Sir Topham and Lady Hatt are visiting the Skarloey Railway, and the brass band have been invited to play. Rusty takes the band on a tour of the Skarloey Railway, but forgets to return on time and runs out of fuel on the causeway. Luckily, Rusty is able to use his distinctive two-tone horn and the band's music to alert Mr. Percival, the Hatts, and the engines, who come to the causeway to listen to the concert.
