This is the sixteenth remake of my channel, and this is another one of my favorite episodes of Season 2 of Thomas and Friends. It's called Percy Takes the Plunge, narrated by Ringo Starr in the UK. My favorite narration is Ringo Starr's US narration. Enjoy!

Percy thinks that water is nothing to an engine with determination, but his mood soon changes when he passes a danger sign at the harbour.

At Brendam, a tired Henry is looking to rest. However, he is annoyed to find Percy telling Bill and Ben about the time he braved bad weather to help Thomas' passengers return home. Percy claims that "Water's nothing to an engine with determination," while the twins shower him with praise. Henry arrives and angrily sends them away, claiming that the shed is only for engines belonging to the Fat Controller. Henry also thinks Percy is silly for his remark about water. Percy runs off, singing about the time that Henry refused to leave a tunnel in case the rain spoilt his paint, to Henry's annoyance as he huffs to himself that no one will ever let him forget that incident.
Percy finds Thomas looking at a "Danger" board on the quayside. Thomas tells Percy that they must not go past it, recalling when he went past it and fell down a mine. What Percy does not realize is that the foundations of the quay have sunk, causing the tracks to slope downward into the sea. As a result Percy who is now feeling very cheeky remarks that the board is stupid and makes a plan to pass it.
One day, Percy is taking a line of trucks to the harbour. He secretly asks them to give him a bump once they get to the quay. The trucks happily agree, having never been asked to bump an engine before. Percy thinks that he can stop the trucks whenever he likes, but every wise engine knows that trucks are never to be trusted.
At the quay, Percy stops before the sign, convinced his plan will work, but the trucks seize the opportunity and bump Percy hard enough to knock his crew off the footplate. Percy is frantic and urges the trucks to stop, but they ignore him and cause him to slide downward into the sea. The Fat Controller arrives on a boat and scolds Percy for his deliberate disobedience. Percy begs to get out, but the Fat Controller sternly refuses, as they cannot do that until high tide, hoping it will teach Percy to obey orders. When night falls, floating cranes are brought in to hoist Percy from the sea and onto a flatbed as he has become too cold, filthy, and stiff to move.
The next morning, Percy is taken to the Works to be cleaned and mended on Henry's goods train. Henry finds the incident very amusing, telling Percy he needs more determination and suggesting that he will like it better next time. Percy however is determined that there will not be a "next time".
