Thomas & Friends Season 6 Episode 21 Thomas, Percy and the Squeak Episode Title:Thomas, Percy and the Squeak.Episode Description:Thomas is chosen by the Fat Controller to collect famous Italian singer Alicia Botti from the docks, meaning that he gets to be cleaned ahead of Percy, who is indignant at this, as he is a guaranteed connection. Once clean, Thomas feels very important, but then hears a squeak, and his driver cannot figure out where it is coming from. However, when he arrives to collect Alicia Botti, she screams shrilly at the sight of a mouse aboard Clarabel, much to Gordon's amusement. The Fat Controller is very embarrassed, and Thomas does not feel important anymore. Percy gladly takes over and collects Alicia Botti instead, as she considers him a proper engine for his dirtiness, despite Gordon disapproving of this. At the wash-down later, Thomas apologizes to Percy for acting inconsiderate, and allows him to be cleaned first. The two friends reconcile and make a home for the mouse in the sheds.
