"Definitely a coloratura."
— Gordon after hearing Alicia Botti scream

Thomas, Percy and the Squeak is the twenty-first episode of the sixth season.


Alicia Botti, a famous opera singer, is coming to Sodor for a concert and the engines are wondering who will take her to the venue at the castle. They all agree, however, that Percy will not be chosen as he is very dirty. Come the following day, the Fat Controller had chosen Thomas and tells him to be squeaky clean.

Thomas goes to the washdown where Percy is waiting to be cleaned. However, Thomas insists that he must go next as he has an important job. Percy sets off, still dirty, to collect some coaches for his guaranteed connection. Once Thomas and his coaches are cleaned and prepare to set off, however, they hear a squeak. His crew assume that Annie and Clarabel's wheels are the cause of this, so they oil them. But, once on the move again, the squeak continues on, making Thomas worried.

At Brendam, Thomas pulls up to collect Alicia Botti and the Fat Controller opens one of Clarabel's doors. Unfortunately, there is a mouse inside, which causes Alicia Botti to scream in horror; she screams so loudly that all of the windows around Brendam shatter. Gordon then remarks she is definitely a coloratura. Alicia Botti refuses to ride in Clarabel, much to the embarrassment of Thomas and the Fat Controller. Because of this, Thomas didn't feel important at all. Just then, Percy arrives back from his guaranteed connection and Alicia Botti considers him as a proper engine because of his dirty appearance and decides to ride in one of his coaches instead.

Later, Thomas is back at the washdown when Percy arrives. This time, he lets Percy go next for his wash. That night, whilst Alicia Botti is performing her concert at the castle, Thomas and Percy are at Tidmouth Sheds where the mouse, whom Thomas named "Alicia," now lives.




  • Extended stock footage from Percy's Chocolate Crunch is used, as well as edited stock footage from Scaredy Engines.
  • Alicia Botti's scream was used from a woman's scream from the 1996 film "Independence Day."
  • A script dub of the episode was done in the Japanese show "Ponkids 21," with Leo Morimoto respiring his role as the narrator, with members of REAL BLOOD doing the character voices. Leo later voiced James in another take.
  • The squeak is different at the end on the Bumper Party Collection! DVD.
  • In the last close-up of Alicia Botti screaming, there is an effect of her tongue seen in her mouth.
  • In the UK dub, Gordon calls Percy a peasant after Alicia Botti says Percy is a proper steam engine. This remark from Gordon was taken out and replaced in the US dub with him simply saying "But he's filthy!"
  • This episode could have been filmed alongside Edward the Really Useful Engine. The scene at Knapford in this episode looks pretty similar to the first scene at Knapford in that episode. The same people are boarding the same trains, the same engines are in the same spots, and the same posters are up.


  • At the beginning a poster of Alicia Botti is visible; it says she is performing at the castle tonight, but she was performing the next night. Her name is also misspelled as "Allicia."
  • When Thomas arrives at the docks, his steam platform is visible.
  • Gordon's front and rear bogie are severely derailed in the last scene of Thomas and Percy at the washdown.
  • When Percy arrives at Brendam, some of the steam from his funnel disappears, indicating a film cut.
  • Alicia the mouse is missing her forepaws when she is inside Clarabel.
  • When James boasts about the Fat Controller picking him, he looks unhappy.


  • Percy: Don't call me dirty Percy!


  • Alicia Botti: A mouse!!! (US version) (screams very loudly, causing some windows to break)
  • Gordon: Definitely a coloratura. 
  • Alicia Botti: I can't possibly travel in coaches riddled with mice!


  • Alicia Botti: Look at the little green engine! So-a sweet and-a dirty like a proper steam engine!
  • Gordon: But he's filthy!


  • Gordon: Peasant!
  • Percy: Yes, I am pleasant!
