Theodore's Whistle is the first episode of the second season.


Theodore thinks that his cute, little whistle is not fit for an important, special tug in charge. He tries so hard to whistle like the big tugs that soon he can't whistle at all. As a result, he misses out on one of his favorite jobs, escorting the grand ocean liner Queen Stephanie. When he finds out that the Queen missed his unique whistle, Theodore learns to appreciate the value of who he is.



  • This story received a book adaptation due to popularity.
  • New models of the tugs were used in this episode onwards.
  • First appearance of Katherine.
  • The Swedish VHS title translates to "Horn", while the DVD title translates to "Theodore's Horn".
  • Going by filming order, this is the thirteenth episode of the second season.


  • When The Dispatcher makes his surprise announcement in one shot, Katherine is behind Theodore and Hank, and in the next shots, she disappears. This is because footage from Emily the Vigorous is used.
  • Hank usually pulls barges from the side, but in this episode, he pulls Bobby Barge from the front.
  • Katherine's eyes are wonky in two scenes.
  • Owan's eyes are wonky.
