Since the Clay Pits had been closed for a while due to the rock slide, Bill and Ben would be without work. So Sir Topham Hatt arranged for them to go to Anopha Quarry and help Mavis with the shunting.
Mavis and her intern, Trixie, were wary about about the newcomers. No matter how hard they tried, they couldn't escape falling victim to or witnessing the naughtiness brought in their mist. Wherever they found Bill, they would find Ben. Wherever they found Ben, they would find Bill. The same could be said for Snips and Snails.
However, as the first few days rolled by, the girls have come to accept the twins both as keen workers and good company.
One day, Sir Topham Hatt and an inspector came over to examine his quarry engines.
Inspector: Well, Mavis and Bill, I'm pleased to say that your engines are in fine working order.
Sir Topham Hatt: Unfortunately, Ben, your engine has damaged buffers. You must report to the Steamworks immediately for a new set; Snails shall accompany you there. Mavis and Trixie, you will have to work with Bill and Snips until Ben and Snails return.
Mavis: Yes, Sir. We'll make sure they're kept out of mischief.
Trixie: No quest shall be too troublesome for the Great and Powerful Trixie! *pauses* I mean, you can count on us.
Satisfied, Sir Topham Hatt and the inspector drove away.
Ben was more than just happy to be sent to the Steamworks; he was getting all puffed up. He didn't hesitate in gloating to his brother.
Ben: I'm getting new buffers for my engine! That's proof that I'm obviously special.
Bill: Hold on, hold on a minute. If you're getting new buffers for your engine, so should I. I mean, we're twins! We do everything together!
Ben: *smirking* But you don't need new buffers.
Bill: *snorting* You're only getting them because you're so clumsy with the controls.
Ben: No I'm not!
Bill: Yes you are!
Ben: I'm not!
Bill: You are!
It wasn't just the twins who were arguing.
Snips: You know, I have a feeling I know what's gotten Ben so sloppy lately...
Ben: *indignant* Sloppy?!?
Snips: Yeah. And the problem's right next to me.
Snails looked to his left and right. He had a rather clueless look. Snips gave a resigned sigh.
Snails: *scratching his head* Duh... I don't get it, Snips. What's the problem?
Snips: The problem, Snails, is that you're so thick, you can't tell a regulator from a brake or a safety valve from a piston.
Snails: *gasp* Are you saying I'm dumb???
Snips: Finally, you're catching on.
Snails: *smiling* Oh, thanks. *realizes* Hey!
Snips: Why you got to be Ben's intern, or anyone's intern, is beyond me.
Snails: Well... how come they've hired you if you're so fat?
Snips: Hey! I'm not that fat!
Snails: Okay, how about round?
Snips: Zip it!
Snips: Knock it off!
Snips: I SAID SHUT UP!!!
By now, Mavis and Trixie had heard enough of this.
Mavis: Will you four stop being crackpots?
Trixie: *groaning* Save your stupid arguing for another time. It's giving Trixie a headache. And my feet are killing me from standing around here...
Mavis: Plus, I have a date with Toby after the shift. Now come on, Bill and Snips. We've got work to do.
Bill: *grouchily* Fine.
Snips: *flatly* No complaint from me.
Bill and Snips got into their engine and followed the girls off to work.
Ben could hardly wait for his engine's new buffers. Snails was rather upset with how Snips had called him stupid. Even if both the twins agree with Snips, as well as everyone else on Sodor, Ben went out of his way to cheer his intern up.
Ben: Don't be so sore, Snails. Snips' just jealous that you get to have some time off and he doesn't.
Snails: *brightening up* Well... I could use a break.
Ben: That's more like it.
Later, Bill and Snips watched as Ben and Snips drove away to the Steamworks.
Snips: *grumbling* Least it'll get me away from that moron for a while. I can actually relax...
Snails: *calling out* See you later, fatso!
Snips: I'M NOT THAT FAT!!!
Snails: Says you!
Bill hardly registered what was being said by Snips and Snails. He was green with envy, both figuratively and literally. He wanted new buffers, too.
Later, as worker and intern went back to work, Bill wasn't paying attention. All he could think about was Ben getting new buffers. He thought so much about this, he didn't hear Snips warning him until it was too late.
Snips: Bill, look out! The buffers...!
The tank engine rammed the truck they was shunting into a set of buffers. The impact nearly knocked Snips and Bill off their feet.
Bill: Oof! That wasn't pleasant!
The crash also caused a pipe to slide off the roof and into the engine's funnel.
Snips: *sighing* I've got this...
As Snips hopped off and walked towards the front of the engine, he slipped and fell on a board, which catapulted a bucket full of dust into the air. It fell right onto Bill's head.
Bill sneezed so hard, the bucket flew off, attracting Mavis and Trixie's attention.
Mavis: Be careful, Bill! And quit thinking about Ben's new buffers.
Trixie: Make sure he gets a smaller leash, will you, Snips? We don't need another Snails...
Snips: *irritated* What am I, a babysitter? Sheesh!
Bill tried thinking about birds. He tried thinking about trees. He even tried thinking about a huge chocolate sundae with marshmallows and caramel on top.
He tried thinking about anything but Ben and his brand new buffers. But it didn't work.
Bill: I want new buffers, too!
Mavis: Just be glad your engine's in good working order.
Snips: Yeah, it's not the end of the world. Take a chill pill.
Bill: It's not fair!
Bill was so upset, he accidentally pulled his engine's regulator and caused it to blow steam and soot all over Mavis and Trixie.
Mavis: *coughing* BILL!!!
Trixie: My clothes! My hair! All ruined!
Bill: *meekly* Oops. Sorry, girls...
Mavis: *panicking* I can't go out with Toby looking like this! Trixie, I have to hit the showers fast! Cover for me!
And so, Mavis ran off in a hurry, leaving Trixie absolutely flustered.
Trixie: But I... I need to take a shower too, Mavis! Not that I'm expecting some cute boy to look at me after the shift! *pause* Mavis?
Snips: *snickering* Guess your stuck with us for a while, Trix...
Trixie just growled and set back into the Class 04. This day was getting worse with every hour.
Bill tried his best to get on with his work, but the troublesome delinquents spotted a chance for a tease.
Delinquents: Poor, poor Bill; he works, he suffers
While Ben, his twin, gets brand new buffers
This made Bill crosser than ever.
Bill: I might not have new buffers, but I still know how to biff you lot!
And he switched the reverser at full maximum.
Snips: *worriedly* Bill, what you are doing?
Trixie: BILL, NO!!!
But it was too late. Bill rammed the trucks behind him so hard, he broke through a set of buffers behind him, causing the trucks and the engine to fall into a rock ditch.
Luckily, no one was hurt.
Mavis heard the crash and rushed out of the women's locker room, having gotten her shower and a clean set of clothes on.
Mavis: What's going on out here?
Trixie: *pointing towards the ditch* Take a guess...
Mavis: *groaning in frustration* I warned you to calm down, Bill! Now looks what's happened!
At that moment, in came Ben and Snails in Ben's engine. The engine had a pair of shiny, silver buffers at the front. They were just in time to hear...
Bill: Bust my buffers!
Ben: *smirking* I think you have.
Snails: *chuckling* Who's the dumbhead now, Snips?
Snips: That wasn't me! And I'm still gonna go with you!
Ben: Come on, Snails. No use arguing here. Let's go fetch the Breakdown Train.
Soon, Jerome and Judy were brought to help with the mess. Sir Topham Hatt was on board one of the coaches. When he saw Bill in the pit and his engine's broken buffers, he was not happy in the slightest.
Sir Topham Hatt: Bill, you have behaved badly ever since Ben went to the Steamworks. Do you have anything to say for yourself?
Bill: *gulp* Yes, Sir. I'm sorry, Sir.
Sir Topham Hatt: Before you get new buffers, I want you to remember what it means to be a responsible, reliable worker. Understand?
Bill: *quietly* Yes, Sir...
After Sir Topham Hatt had left, and Bill's engine was back on the rails, Ben drove over to see him. His engine's buffers were glistening in the sun.
Bill: They sure are nice buffers.
Ben: Thanks, bro. I'm sorry I teased you.
Bill: Ah, that's alright. I was naughty, too.
Ben: Of course, you were! We're twins!
Snips: Snails, I'm sorry for calling you stupid this morning.
Snails: *shrugging* No worries, Snips. It varies. And I'm sorry I called you fat.
Snips: Actually, I have been gaining a few pounds lately. Might as well lose 'em before the week is out.
Snails: Want me to teach you some rock sliding?
Snips: *winking* You're on, my faithful birdbrain.
Bill and Ben: Hey, count us in too!
And so the foursome set out to have some fun, just like friends always do.
Bill and Ben can still be cheeky at times, but they still try their hardest to be really useful.
