This time, it was the turn of Percy and the Monster of Brendam where the incumbent green engine became convinced that there was a Monster of Brendam and so went forth with a search in the fog.
A sizeable cast featured in the story alongside Percy such as Salty, Cranky, Edward, Toby, Henry and company from Butch and Diesel.
In a suprise turn around, Thomas was amongst the set of cameos and had not done such appearance since The Party Surprise back in the Twelfth Series.
Joining Thomas silent wise consisted of Annie and Clarabel, The Fat Controller, James, Gordon, Emily and Stanley.
The episode gathered generally negative reviews who were disappointed with the poor and formulaic storyline, also attacking the meddling of Edward, Henry, Toby and Percy's personalities.
Fans found it pointless for Percy to track down the so called Monster of Brendam through parts of Sodor, even though the myth clearly stayed at the Docks.
With rhymes and repeated circumstances bothering viewers more, dim strands included Henry reversing to find the mystery dangerously in the fog, the term Steamie reinstated and the easy identified end utilizing Cranky as the Monster.
That aside, moments of humour connected with watchers such as Diesel's Whose calling me a monster? line, Keith Wickham's Salty performance and Edward's minor crash.
Another show-up by an LMS Brake Van was also well recieved as was the long-awaited non-speaking role of Thomas, whose face could not be seen when at Knapford Station near the beginning of the show.
Before the airing, three of milkshake!'s presenters proceeded with the usual Thomas, You're the Leader! dance masterclass. However, instead of the studio, Derek Moran, Jen Pringle and Kemi Majeks were on location.
The three also joined by Thomas, had filmed a special insert at the East Anglian Railway Museum for the dance to take place.
