A Herschend Entertainment Studios Production.

Cartoon trains move in an animated city.

A loudspeaker says, HONK YOUR HORNS!

Colourful trains move along tracks.

People cheer, CHUGGINGTON!

Singers sing, A GREAT BIG TOWN OF TRAINS
AND TRACKS.
WHEELS TO THE RAILS.
CLACKETY-CLACK.
ADVENTURE AND FUN 'ROUND
EVERY BEND.
COME RIDE ALONG WITH YOUR
CHUGGER FRIENDS

A red train says, I'M WILSON.

A yellow and blue train says, I'M BREWSTER.

A green train says, AND I'M KOKO!
CHOO-CHOO!

Singers sing, HONK YOUR HORN, CHOO-CHOO!
CHOO-CHOO!
CHUGGINGTON.
CHUGGA-CHUGGA-CHUGGA
CHUGGA-CHUGGINGTON.
CHUGGINGTON.
CHUGGA-CHUGGA-CHUGGA
CHUGGA-CHUGGA-CHUGGA
CHUGGA-CHUGGA-CHUGGA
CHUGGA-CHUGGINGTON.
CHUGGINGTON!

Title, Chuggington.

People say, CLACKETY-CLACK!

A person reads a title.

They read, KOKO AND THE TUNNEL.

(Chimes)

Vee, the loudspeaker, says, WILSON, BREWSTER
AND KOKO TO THE TRAINNG YARD,
PLEASE.

Text below the title reads, by Sarah Ball. Horns honk as the chugger friends Wilson, Brewster and Koko travel through Chuggington. They approach a red light.

Brewster says, STOP CHUGGERS!

A horn honks and bells ring as a train passes the friends and enters a tunnel. Koko looks curious.

She says, HEY, DOES ANYONE KNOW WHERE
THIS TUNNEL GOES?

Brewster says, EMERY SAID IT WENT UNDER THE
CITY.

Koko says, OOH, I'M GOING TO ASK VEE.

Wilson says, BUT WE NEED TO MAKE TRACKS,
KOKO.
DUNBAR'S WAITING FOR US.

Koko says, I'LL JUST BE TWO
CLICKETY-CLACKS.

Koko backs up to one of Vee’s loudspeakers.

Koko says, KOKO TO VEE.

Vee says, YES, KOKO?

Koko asks, CAN WE EXPLORE THE
UNDERGROUND TUNNEL?

Vee says, NOT TODAY, KOKO.
THERE ARE SOME IMPORTANT THINGS
TO LEARN BEFORE YOU CAN GO DOWN
TUNNELS ON YOUR OWN.

Koko asks, BUT WHERE DOES IT COME OUT?
HOW LONG IS IT?
WHO USES IT?

Vee says, ALL IN GOOD TIME, KOKO.
NOW OFF YOU GO.

Koko looks disappointed.

She says, OH, OKAY, VEE.
SEE YOU LATER.

Koko returns to her friends.

Wilson cheers, WOO-HOO, IT'S TRAINING TIME.

Wilson and Brewster race down the tracks. Koko stops outside the below ground tunnel and peaks inside. A horn honks and she races after her friends. The chugger friends arrive at the training yard and join Dunbar.

Dunbar says, OKAY, YOUNG CHUGGERS.
TODAY I'M GOING TO SHOW YOU HOW
TO SWITCH TRACKS.

Brewster says, BUT DON'T TRACKS SWITCH ON
THEIR OWN?

Wilson says, YEAH, THEY JUST SEEM TO KNOW
WHERE YOU WANT TO GO.

Dunbar says, ONLY IN THE DEPOT.
ONCE YOU LEAVE HERE, YOU HAVE TO
SWITCH THEM YOURSELVES.

Brewster sighs.

He says, MORE THINGS TO THINK ABOUT.

Koko says, I BET IT'S EASY TO DO.

Dunbar says, EASY WHEN YOU KNOW HOW.
OKAY CHUGGERS, DRIVE FORWARD AND
GO RIGHT AT THE TRACK SPLIT.

Brewster pulls forward and tries to go right on the track split. He grunts and fails to go right. Wilson makes the same attempt followed by Koko. All chuggers fail.

Wilson says, HUH?

Brewster says, IT DIDN'T WORK.

Koko says, OH, I CAN'T GO RIGHT, IT
WON'T LET ME.

Wilson asks, WHY WON'T IT MOVE?

Dunbar says, BECAUSE THE SWITCHES ARE
POINTING STRAIGHT AHEAD.
DO YOU SEE HOW THE ARROW SHOWS
YOU WHICH WAY IT GOES?

The chuggers back up behind a sign with an arrow pointing straight.

Brewster says, OH, YEAH.

Dunbar says, NOW WATCH.

(Clang)

The arrow switches, pointing to the right.

Brewster asks, HOW DID HE DO THAT?

Dunbar says, WELL, YOU EACH HAVE YOUR OWN
CONTROL INSIDE YOUR –

Koko drives down the track.

Vee interrupts saying, DUNBAR, I NEED YOU TO GO OUT
ON A JOB URGENTLY.

Dunbar says, ON MY WAY, VEE.
SORRY YOUNG CHUGGERS, WE'LL HAVE
TO FINISH THIS LATER.

Dunbar honks and leaves.

Brewster says, LET'S WORK OUT HOW TO DO IT
BY OURSELVES, THEN DUNBAR WILL
BE REALLY PLEASED.

Wilson says, YEAH, GREAT IDEA.

Wilson looks at the arrow sign.

He says, SWITCH MOVE OVER.

Wilson closes his eyes. He opens them.

He asks, ANYTHING HAPPENED?

Brewster says, NOPE.

Wilson says, HM.

Brewster says, WE HAVE TO FIND THE CONTROL.

Wilson grunts. His and Brewster’s eyes cross. The sign doesn’t change. Horns honk and Wilson groans. His light flickers.

Wilson says, MUST BE ONE OF THESE.

His horn honks and his door opens. The arrow remains the same and Wilson groans.

He says, WHICH ONE IS IT?

Wilson tries again. He narrows his eyes, grunts, shakes and beeps. Wilson lets out a breath

He says, HUH!?

Wilson squeaks. His door opens and windshield wipers activate. The arrow remains in place.

Brewster says, MAYBE, WE JUST HAVE TO THINK
REALLY HARD ABOUT MOVING IT.

Wilson says, YEAH, LET'S TRY THAT.

Wilson crosses his eyes. He and Brewster shake as they try again. Koko returns.

She says, AH, THIS IS RIVETING.

Brewster asks, WELL, HAVE YOU GOT A BETTER
IDEA?

Koko says, YEAH, I'M GOING TO EXPLORE
THAT TUNNEL.

Brewster says, HONKING HORNS, THAT'S THE
CRAZIEST THING I'VE EVER HEARD.

Koko asks, WHO'S COMING?

Brewster says, NOT ME.

Koko says, I DIDN'T KNOW YOU WERE SUCH A
SCAREDY CHUGGER.

Brewster says, I'M NOT.

Koko says, SCAREDY CHUGGER, SCAREDY
CHUGGER.
COME ON, WILSON, IT'LL BE OFF
THE RAILS, A REAL ADVENTURE.

Wilson gasps.

He says, AN ADVENTURE?
WOO-HOO!
OKAY, I'LL COME.

Koko says, DON'T TELL ANYONE WHAT WE'RE
DOING, BREWSTER.

Brewster says, WELL, DON'T BLAME ME IF YOU
GET INTO CAR-LOADS OF TROUBLE.

Koko and Wilson leave.

Brewster says, DON'T BE LONG, JUST A QUICK
PEEK, OKAY?

Brewster gets no response.

He says, OH...

Brewster looks sad. In the underground tunnel, Koko giggles.

She says, THIS IS SO MUCH FUN.

Koko rides the track down into the tunnel.

Wilson says, LET'S RIDE THE RAILS.

He follows Koko into the tunnel. Their lights shine in the dark tunnel. Koko looks around excitedly. Wilson starts to look nervous.

Wilson says, MAYBE WE SHOULD GO BACK NOW.

Koko says, NO WAY.
WE NEED TO SEE WHAT'S ON THE
OTHER SIDE, THEN WE'LL GO HOME.

Koko and Wilson ride uphill in the tunnel.

(Birds chirping)

Wilson gasps as he and Koko exit the tunnel.

Wilson says, COUNTRYSIDE!

The chugger friends stop outside the tunnel.

Koko says, WOW!
IT'S SO BEAUTIFUL.

Wilson says, WE MUST'VE COME A REALLY LONG
WAY.

Wilson follows Koko down the track.

(Mooing)

Wilson says, YIKES, WHAT WAS THAT?!

Koko says, AW, IT'S JUST A COW.

Cows walk alongside the tracks.

Koko says, HELLO.

A cow moos.

Wilson says, KOKO, WE SHOULD GO BACK NOW.

Koko says, BUT –

Wilson says, KOKO, YOU PROMISED.

Koko says, OH, OKAY.
LET'S FIND SOMEWHERE TO TURN
AROUND.
C'MON, BETCHA CAN'T CATCH
KOKO!
GO KOKO, GO KOKO, GO KOKO!

Koko pulls ahead.

Wilson says, I WANT TO GO HOME.

Back in the training yard, the arrow sign flickers between directions.

Brewster says, TURN RIGHT, TURN RIGHT.

Brewster tries to turn onto a track. He fails to turn and skids to a stop.

He says, HONKING HORNS.

Brewster backs up.

He says, OH, THIS IS HARD.

Peckham the dog joins Brewster.

Brewster says, HELLO PECKHAM, I'M REALLY GLAD
TO SEE A FRIENDLY FACE.

Peckham sits and barks.

Brewster says, I'M ALL ON MY OWN.

He honks and his doors flap open.

He says, OOPS, BUT, DON'T TELL ANYONE,
OKAY?

Peckham barks. In the countryside, Koko and Wilson approach a sign with an arrow.

Koko says, WE CAN TURN AROUND HERE.

She stops at the sign.

Koko says, UH-OH, A SWITCH, AND IT'S
TURNED THE WRONG WAY.

Wilson says, OH, BUMPERS!

Wilson gasps.

He says, WHY DIDN'T DUNBAR FINISH
TEACHING US HOW TO MOVE THEM?

Koko says, MAYBE IT WILL MOVE IF I DRIVE
TOWARDS IT.

Wilson says, I DON'T THINK SO, KOKO.

Koko races toward the turn in the tracks. She grunts when it doesn’t switch. Koko makes multiple attempts until she bounces off the track.

She says, OH, NO!

Wilson gasps.

He asks, ARE YOU OKAY?

Koko says, YES, BUT I CAN'T MOVE.

Koko moves her wheels but she only blows dust from the ground.

She says, I'M REALLY STUCK.

Back in Chuggington, Brewster travels with Peckham.

(Dinging)

Brewster sighs.

He says, STILL NO SIGN OF WILSON AND
KOKO.

Brewster looks at Peckham.

He says, OH, HOW LONG DOES IT TAKE TO
LOOK DOWN A TUNNEL?

Peckham barks.

Brewster says, YEAH, YOU'RE RIGHT, NOT LONG.
WHAT IF SOMETHING HAPPENED?
MAYBE I SHOULD TELL VEE.

Brewster backs up.

(Mooing)

In the countryside, Wilson looks thoughtful.

He says, MAYBE, I CAN DRIVE BACKWARDS
THROUGH THE TUNNEL AND GET HELP.

Koko says, NO, I DON'T WANT YOU TO HAVE
AN ACCIDENT TOO.
WE'LL JUST HAVE TO HOPE SOMEONE
COMES SOON.

Wilson says, BUT NOBODY KNOWS WE'RE HERE
EXCEPT BREWSTER, AND YOU TOLD
HIM NOT TO TELL ANYONE.

Koko says, I KNOW.
I SHOULDN'T HAVE DONE THAT.

Wilson says, SO, WHAT DO WE DO NOW?

Koko says, IF WE HEAR ANYONE COMING,
WE'LL HAVE TO HONK OUR HORNS
LOUDLY.

Back in the training yard, Brewster looks uncertain.

He says, WHAT SHOULD I DO, WHAT SHOULD
I DO?

Brewster sighs. He backs up to one of Vee’s loudspeakers.

He says, UM, VEE, COULD YOU ASK CALLEY
TO RIDE BY, PLEASE?

Vee says, SURE THING, BREWSTER.

Sirens blare and lights flash above Calley’s train barn. Calley drives into her barn and presses a button that lowers her beneath the barn. A turntable turns her to a car with a small crane with a hook and cable that she connects to before leaving down a tunnel. In the country side, horns blare in the distance Wilson gasps.

He says, SOMEONE'S COMING.

Koko says, LET'S HONK!

Koko and Wilson honk their horns.

Horns honk as a train pulling multiple train cars drives past.

Koko yells, HELP!

Wilson sighs.

He says, WE'RE GOING TO BE STUCK OUT
HERE FOREVER.

Wilson groans. Calley’s sirens blare as she travels down a track.

She says, BREAKDOWN-CHUGGER COMING
THROUGH!

In the countryside, Wilson gasps as Calley’s siren blares in the distance.

Wilson says, WHAT'S THAT?

Koko says, SOUNDS LIKE CALLEY!

Calley appears behind the Wilson and Koko.

Calley says, PHEW, I FINALLY FOUND YOU.
BREWSTER SAID YOU WENT DOWN THE
TUNNEL, BUT I NEVER THOUGHT
YOU'D BE ALL THE WAY OUT HERE.

Wilson says, ME NEITHER.

Koko says, IT'S MY FAULT.
I WANTED TO KNOW WHERE THE
TUNNEL WENT.

Calley says, VEE TOLD YOU THAT YOU WEREN'T
READY TO GO DOWN TUNNELS BY
YOURSELF.

Koko says, I KNOW BUT –

Calley interrupts and says, DIDN'T YOU THINK THERE MIGHT
BE A REASON FOR THAT?
LIKE IT WAS FOR YOUR OWN SAFETY?

Koko says, I GET THAT NOW.

Calley says, C'MON, LET'S GET YOU BACK ON
THE TRACK.

Calley turns the arm of her crane toward Koko and swings the cable. The hook of the cable connects to the back of Koko.

Calley says, HOLD TIGHT.

The cable retracts, pulling Koko. Koko grunts as the cable pulls her back toward the tracks.

Calley says, EASY.
NEARLY THERE.

Koko is pulled back onto her track.

Calley says, GREAT!

Koko says, PHEW.
THANKS, CALLEY.
FROM NOW ON, I'M NOT GOING
ANYWHERE UNTIL I KNOW HOW TO BE
SAFE ON THE RAILS.

Calley says, GOOD CHUGGER.
NOW LET'S GET YOU BOTH BACK TO
THE DEPOT SAFE AND SOUND.

Calley pulls ahead. Koko and Wilson follow the tracks that are now switched, turning them around back to the direction of the tunnel. Horns honk and sirens blare as they make their way back. Koko returns to her train barn with Brewster and Wilson under a night sky. Wilson yawns.

Brewster says, YOU KNOW, IT REALLY WASN'T
A GOOD IDEA TO GO OFF LIKE THAT.

Koko says, I KNOW.
SORRY THAT I MADE YOU SO
WORRIED.
I'M LUCKY TO HAVE A TRAINTASTIC
FRIEND LIKE YOU.

Brewster says, WELL SOMEONE'S GOT TO STOP
YOU GOING OFF THE RAILS!

The chugger friends laugh.

Vee says, GOOD NIGHT, CHUGGERS.

Wilson says, NIGHT, NIGHT.

Brewster says, GOOD NIGHT.

Koko says, SLEEP RIGHT

The chuggers back into their train barns and their doors close.

Vee says, SWEET DREAMS.

Above the train barn is the full moon. Brewster giggles.

Singers sing as credits roll.

They sing, LET'S TRAIN TOGETHER!
WE'RE SO MUCH BETTER
AS A TEAM.
LET'S TRAIN TOGETHER.
TOGETHER!
WORK, WORK, WORK
LIKE A MACHINE.
THERE'S REALLY NOTHING
BETTER THAN TO BE WITH
YOUR FRIENDS.
YOU'LL BE HAVING SO MUCH FUN
YOU'LL WISH THE DAY NEVER
ENDS.
TOGETHER!
