- “The farmer has just telephoned. His straw hasn't been delivered, there are sightseers in his field and his sheep haven't arrived at market!”
- ―Mr. Percival
Duncan Does It All is the twenty-fourth episode of the eleventh series.
Duncan arrives at the Wharf to collect straw and take them to the farm. He tells Thomas about doing the same job all the time and wanted to do something exciting. Rusty came with trucks of slate and was tired with so many jobs to do and that his next on was taking sight seers to the ruined castle. Duncan was excited and wanted to help Rusty, so he left his straw and went to collect Rusty's coaches. He takes them to see fields and forest.
But he soon bores after having to stop at the ruined castle to let them take photos. He sees Skarloey pulling heavy trucks of logs hoping he's not late to collect sheep and take them to market. Duncan volunteers to do Skarloey's job for him and leaves the passengers behind.
After collecting Skarloey's sheep, he meets Sir Handel at a water tower asking him what he's doing today which was to collect the merry-go-round from the Transfer Yards. Duncan goes to do the job for him before Sir Handel could answer him.
When Duncan arrives at the Transfer Yards, he finds Mr. Percival scolding Rusty and Skarloey for muddling everything up. Duncan knows it is his fault and takes the blame, thus Mr. Percival sends him to sort everything out.
Duncan collects his straw, with Thomas surprised to see Duncan as he wanted to do something other than collecting straw, but Duncan insists that he enjoys doing the same job and heads to the farm. On the way he sees Rusty at the castle, who was wondering if he would like to take his passengers to the forest and Skarloey at market who offered him to collect cows, but Duncan insists that pulling straw was more exciting. Duncan arrives at the farm and was happy to be a really useful engine.
