Rusty and the Boulder

"We should have left this part of the Island alone..."

- Sir Topham Hatt

Rusty and the Boulder is the twenty-fifth episode of the fifth series.

Plot
On the Island of Sodor, high up in the mountains, there is a mysterious boulder that has stood alone for a long time. But one day, a new quarry is built near the mines on the land below and Rusty is afraid the giant boulder would fall onto the line. He confesses his fears to Thomas and Percy. Edward arrives with a new machine called Thumper to help with the mining process. Soon, Thumper is working hard. The men are pleased, but no one bothers to check the boulder. However, it starts raining and the workmen leave. Rusty gazes up and shivers at the boulder above. Suddenly, a large slab of rock lands on the rails. Rusty is shocked and worried by this, but his driver is concerned. His driver thinks the rock has been loosened by the rain, but Rusty thinks the boulder is telling them to go away. As they leave, a face mysteriously appears on Boulder and then disappears.

The next day, the sun is shining again and Thumper begins working harder than ever. Suddenly, Rusty notices something; Boulder begins moving, but his driver does not believe him until Boulder falls down and lands on the rails in front of them and begins to chase Rusty. Boulder rolls along the line of the rails as Rusty quickly drives himself backwards to get away from Boulder. Rusty and his driver stop at a junction and wait for Boulder to pass by, but Boulder is nowhere to be seen. Then, they soon realise that Boulder is behind them. Just ahead, they see a small junction, so Rusty races towards it. Rusty takes the line that goes uphill, while Boulder thunders past by them.

Meanwhile, Skarloey is making his way up to the quarry, but he sees Boulder heading for him and catching up fast. He becomes surprised and immediately reverses, but soon slips into a siding, while the Boulder passes by. Boulder destroys the water tower that was in between the tracks. Skarloey tells Rusty that they have to warn the yards, but he does not know how. Boulder rounds a bend and charges towards Rheneas and he races back as fast as he can to get away from Boulder until he crashes into a siding with Boulder just passing by him, much to the relief of his driver. At the yards, Percy is collecting trucks when he heard and saw Boulder approaching. Boulder destroys the neighbouring sheds, engulfing it in flames.

When the Fat Controller inspects the damage, he has no choice but to close the mine. Then he looks at Boulder with the shed, demolished. He realises that they should have left this part of the island alone. At night, they move Boulder to a hill close by the yards so it would never harm anyone or anything on the island anymore. Rusty is sure that, on a clear night, it is gazing high up at the mountains in the distance and that its sighs are being carried on to the wind where it once used to stand, proud and silent.

Trivia

 * Going by production order, this is the twenty-sixth episode of the fifth series and the series finale.
 * Boulder's face is based upon one of Gordon's face masks.
 * The same model for Boulder is used for both the large-scale and normal-scale sets.
 * This episode marks the only appearance of Thumper to date.
 * This episode also marks the only appearance where Terence appears, but without Farmer Finney.
 * In this episode, the quarry was brand new and closed in a short amount of time, meaning the events of Bye George! and Duncan Gets Spooked must have taken place during the events of this episode, as they also took place at the Boulder Quarry yards at the base of the mountain. Furthermore, George is seen at Thumper's dig site before Boulder gets loose, meaning that he served his week-long punishment and was brought back to the quarry to help.
 * The scene where Boulder chases after Rusty is a reference to the Indiana Jones film, Raiders of the Lost Ark. This reference was later used again in the Thomas' YouTube World Tour short, Thomas Goes for Gold.
 * Rusty's small-scale model is used at the beginning and end of the episode, whilst his large-scale model is used for the remainder of this episode.
 * This is one of Davey Moore's favourite episodes alongside Thomas' Train and Luke's New Friend.
 * In the UK version, the line "EYYOIIIKES!!!" was re-used from Busy Going Backwards for Skarloey and Rheneas, when Boulder charges after them.
 * In the US version, the crash sound was heard when Rheneas crashes into a siding with Boulder just passing by him.

Goofs

 * Due to his model being changed, Rusty's face gets bigger and then smaller again throughout the episode.
 * In the close-ups of Rheneas, the hook attached to the camera he is pulling along is visible.
 * In the close-up of Rheneas' driver, his right (viewer's left) pupil appears to be sloppily painted. Also, he appears to be in Rusty's cab instead than Rheneas'.
 * In the US narration, when Percy is at the quarry before Boulder arrives, the British term "trucks" is used.
 * In the second close-up of Percy when Boulder is approaching, it appears that the shed has already been destroyed as the wood from the shed is laying on Percy's trucks.

Quotes
[Edward arrives with a machine named Thumper for the quarry] ____________________________________________________________________________________ ____________________________________________________________________________________ _____________________________________________________________________________________
 * Percy: Where's all this rock coming from?
 * Rusty: The new quarry. This mountain rock is good for many things, although it's dangerous up there.
 * Thomas: Why?
 * Rusty: Because of a big boulder. I think it's watching me.
 * Percy: How can it be? Boulders don't have eyes!
 * Rusty: That says maybe, Percy, but there's something strange about this one. (US: "Well, Percy, there's something strange about this one.")
 * Rusty: What's that?
 * Edward: It's called Thumper. Apparently, it helps collect the rock faster.
 * Rusty: [to his driver] I think it's the boulder wanting us to go away.
 * Skarloey: We must warn the yards!
 * Rusty: Yes, but how?
 * Rheneas's Driver: (relieved) Rather a smash than a squash! (US: "Better a smash than a squash!")
