|Duncan Does it All|
Duncan wants a change from collecting straw and delights in taking Rusty's passengers sightseeing instead. But he soon bores after having to stop at the ruined castle to let them take photos, so he swaps jobs with Skarloey, but he forgets to leave the coaches for Skarloey. After collecting Skarloey's sheep, he meets Sir Handel at a watertower and offers to collect the merry-go-round for him at the Transfer Yards, but arrives to find Mr. Percival scolding Rusty and Skarloey for muddling everything up. Duncan knows it is his fault and takes the blame. Mr. Percival sends him to sort everything out, and Duncan realizes that maybe doing the same thing does not have to be boring.
