[Whistling]

Messy, a furry blue monster with a red nose and a blue tail whistles.

He says, LET'S SKI-DOODLE, OKIDOODLE!

Messy hops into a white and blue convertible. He presses a green button on the dashboard.

Singers sing, MESSY GOES TO OKIDO.

Messy sings, FIND OUT WHAT YOU WANT
TO KNOW.

The singers sing, LET'S ALL GO TO OKIDO.

Messy drives through the countryside past a pond and down a road with dancing trees.

He sings, OKIDO, OKIDO

The singers sing, MESSY GOES TO OKIDO.

Messy drives through OKIDO, a large city with tall, colourful buildings.

He sings, ALL THE THINGS YOU WANT
TO KNOW.

Messy drives onto a loop de loop and underwater.

He sings, COME ALONG AND SAY HELLO.
LET'S GO SEE OUR FRIENDS!

Messy runs into a domed shaped house. Inside, he joins a blue haired boy wearing a striped blue shirt and blue hat.

Messy shouts, FELIX!

The singers sing, IN OKIDO.

A red haired girl wearing red overalls and a red hat waves to Messy.

Messy shouts, ZOE!

Zoe high-fives Messy.

The singers sing, IN OKIDO.

Messy cheers, ZIM, ZAM, ZOOM!

The singers sing, IN OKIDO.

Zim, who has a square shaped body and computer face appears with Zam, a green triangle, and Zoom, a pink creature. Zam’s science experiment explodes, filling the room with smoke.

Messy sings, BA-BA-LA-LA, BOOM-BOOM!

In OKIDO, Messy dances down a street with his friends.

The singers sing, MESSY GOES TO OKIDO
LET'S ALL GO TO OKIDO.
FIND OUT WHAT YOU NEED
TO KNOW.

Messy looks through a magnifying glass.

He sings with the others, MESSY GOES TO OKIDO!

Zoom transforms into a screen that reveals the title, Messy Goes to OKIDO. Messy jumps beside the screen and smiles.

[Rustling]

The episode title reads, Cavity Cave. Written by Andrew Barnett Jones and Ciaran Murtagh. In the bathroom, socks lie on the floor beside a laundry basket that moves.

Messy says, HMM, WHERE IS IT?!

He pops up from inside the laundry basket.

He grumbles, WHERE IS IT?

Messy jumps down from the laundry basket.

He says, NOT HERE.

He looks around the room.

He says, OH, HI!
JUST TRYING TO FIND MY
TOOTHBRUSH.

Messy waves. He hops into the bathtub.

He says, I'M SURE I PUT IT HERE.

A rubber duck bounces onto the floor.

[Squeaking]

Messy says, OR WAS IT...?

He jumps onto the sink and looks at his teeth in the mirror.

He says, MY TEETH ARE PRETTY DIRTY, EVEN
FOR A MESSY MONSTER!

Messy makes silly faces in the mirror.

He says, GRR!
ARGH!
AHH!

Messy slips and falls to the floor.

He says, BUT WHY DO I HAVE TO BRUSH MY
TEETH?
WHY CAN'T I JUST CLEAN THEM WITH
WATER?
HMM.
WHEN YOU NEED TO KNOW, GO TO
OKIDO!

[Magical music plays]

A green and white tunnel transports Messy to OKIDO. Messy bounces down a set of trampolines. He flips off the last trampoline and lands on his feet beside Felix and Zoe. Felix and Zoe are cleaning the white and blue convertible, which is covered in mud.

Messy says, HI, ZOE, HI, FELIX.

Zoe says, HI, MESSY!

Messy says, HEY, WHAT HAPPENED TO
OKIDOODLE?
HE'S BRILLIANTLY MESSY!

Zoe says, HE WENT OFF-ROAD AND GOT ALL
MUDDY.

Felix says, SO WE'RE GIVING HIM A BATH,
BUT IT'S TAKING AGES!

Messy says, NOT USING THE MESSY MONSTER
METHOD!

Felix says, UH, WHAT'S THE MESSY MONSTER
METHOD?

Messy cheers, WHEE-HEE!

He flies around with a powerful garden hose.

[Messy cheering]

Messy sprays Okidoodle, the convertible, with the garden hose water.

[Felix laughing]

Felix hides from the spraying water. Zoe runs over to the water valve and turns off the water.

Messy cheers, WHOA-HO!

He drops to the ground as the water shuts off.

He says, THAT WAS GREAT!

Laughing, Felix says, YEAH, BUT OKIDOODLE IS STILL
DIRTY.

He looks at the muddy convertible. Zoe joins Felix.

She says, THE MUD'S REALLY STUCK ON.
MAYBE WE NEED TO SCRUB IT OFF?

Felix grabs a brush.

He says, THIS SHOULD HELP.
MESSY, MORE WATER, PLEASE.

Messy opens the water valve, turning on the water. He runs over to the car and grabs the hose. Messy sprays Okidoodle. Felix scrubs the mud.

Messy says, YAY, SCRUBBA-DUB-DUB!

[Brush squeaking]

Zoe turns off the water. Water drips down Okidoodle.

[Rumbling]

The ground shakes.

Messy, Zoe and Felix say, WHOA!

The three friends stumble.

Zoe says, WHAT IS GOING ON?

Messy stumbles and falls into the mud. Mud splatters onto Okidoodle.

[Mud splattering]

Messy says, WHOA!
WHAT WAS THAT?

Felix says, I DON'T KNOW.

[Zoe gasping]

Zoe says, LOOK, IT'S MADE OKIDOODLE
DIRTY AGAIN!

Messy looks at the muddy convertible.

Zoe says, HOW ANNOYING!

[Rumbling]

The cloud ship is flown toward the friends.

Zoe says, MAYBE ZIM, ZAM AND ZOOM KNOW
WHAT'S CAUSING THESE RIDICULOUS
RUMBLES?

Zoe, Messy and Felix run over to the ship as it lands. Zim, Zam and Zoom walk out of the ship. Zam carries a small device.

Zim asks, DID YOU HEAR THAT?

[Rumbling]

Everyone stumbles as the ground shakes.

They wail, WHOA!

Messy falls.

He says, YES, I HEARD IT.
AND I FELT IT, TOO!

Zam says, LOOKS LIKE MY RUMBLE HUNTER
WORKS.
WHO'D HAVE THOUGHT?

She looks at her device.

She says, WE'RE FOLLOWING IT TO TRY AND
FIND WHERE THESE RUMBLES ARE
COMING FROM.
THEY'RE GETTING STRONGER.

Zim says, AND THEY'RE REALLY STARTING
TO CAUSE TROUBLE
LOOK.

He points to Zoom, who transforms into a screen. Zoom shows a map of OKIDO with three pulsing red dots in three different locations.

[Alarm sounding]

[Rumbling]

In a diner, a creature stumbles. They drop their tray, and fall.

The creature says, WHOA, AUGH!

Elsewhere in OKIDO, a robot hangs an art piece.

[Rumbling]

The robot stumbles. The art piece falls off the wall.

The robot wails, AUGH!

[Glass breaking]

At his table, Mayor Oki says, RIGHT, TUCK INTO BREAKFAST...

[Rumbling]

Mayor Oki grunts, OH, UGH!

His breakfast spills all over his face.

Messy says, WOW , THOSE RUMBLES ARE
MESSING UP THE TOWN, BUT NOT IN
A GOOD WAY.
AND I NEVER THOUGHT I'D SAY
THAT!

Zam says, THE RUMBLE HUNTER SHOULD LEAD
US TO THE SOURCE OF THE RUMBLES.

Zoom shows a new pulsing red dot on the map.

Zim says, OH NO, THE RUMBLES HAVE GOT
THE JELLY SHOP WOBBLING!
WHEN THAT PLACE STARTS WOBBLING,
IT MIGHT NEVER STOP!

An animation shows the jelly shop, made of jelly, exploding. Zoom returns to his normal self.

Zim says, WE'D BETTER GO AND HELP THEM.

Zam says, WE'RE GOING TO NEED YOUR
HELP.

Messy says, OKIE-DO!

Zam says, TAKE MY RUMBLE HUNTER AND
HUNT DOWN THOSE RUMBLES.

She hands Zoe the Rumble Hunter.

Zim says, LET US KNOW WHEN YOU'VE FOUND
WHAT'S MAKING THEM.
WE'LL BE AT THE JELLY SHOP!

Zim, Zam and Zoom leave in the cloud ship.

Messy says, HEY-HEY-HEY!
WE'RE THE RUMBLE HUNTERS!

Zoe says, COME ON, WE'D BETTER HURRY!

Messy says, OKI-DOO-DA-DOODLE!

Felix says, I NEED TO PACK A FEW THINGS.

He throws the cleaning brush in his bag.

He says, YOU NEVER KNOW WHAT WILL COME IN
HANDY.

Felix struggles to lift his bag.

[Felix grunting]

[Rumbling]

The ground shakes.

Zoe says, THERE ISN'T TIME.
COME ON.
WE NEED TO STOP THOSE RUMBLES!

Felix joins Zoe and Messy in Okidoodle.

Messy says, LET'S SKIDOODLE, OKIDOODLE!

He zooms through the countryside.

[Zoe and Felix laughing]

Messy says, HOLD TIGHT, EVERYONE!

He races past a piece of walking land and trees crossing the street.

[Laughing]

Messy drives around a curve. His eyes widen as he approaches a turtle. The turtle ducks inside his shell. Messy drives over the turtle, making the turtle spin. Messy drives up to a bridge beside a waterfall on a mountain.

Zoe says, THE RUMBLE HUNTER IS TELLING
US TO GO OVER THAT BRIDGE.

Messy drives up the bridge. The ground shakes.

[Rumbling]

Messy, Zoe and Felix say, WHOA!

A board in the bridge loosens and Okidoodle’s back wheel gets stuck.

Messy says, OH, NO, WE'RE STUCK!
EVERYONE, PANIC!

Through Zoe’s watch, Zim says, COME IN, ZOE.

Zoe answers a video call on her watch.

[Watch beeping]

Zoe says, HI, ZIM.

Zim asks, HAVE YOU FOUND THE SOURCE OF
THE TREMORS?

At the jelly shop, jelly creatures bounce around. Zam runs through the shop.

Zoe says, WE'RE GETTING CLOSER.
UM, OVER.

Zim says, HURRY!
THE JELLIES ARE OUT OF CONTROL!

A jelly slams into Zim. The call ends.

Zoe says, HURRY, MESSY!
HIT THE RED BUTTON!

Messy looks excited. He raises his hand toward a red button on the dash board.

[Felix gasping]

Felix says, NOT THE RED BUTTON!

Messy says, BUTTON!

He presses the red button. The back tires grow bigger and an engine pops out of the back of Okiedoodle.

[Engine roaring]

[Tires squealing]

Messy crosses the bridge.

He says, LET'S SKIDOODLE, OKIDOODLE!

He races down the street and up the mountain. At the top, a cave in the mountain appears to have eyes, a nose and mouth with dirty stone teeth.

Zoe yells, MESSY, STOP!

Messy stops Okiedoodle.

[Tires screeching]

Zoe says, THE RUMBLE HUNTER IS POINTING AT
THAT CAVE.

A voice whines, OW!

Messy jumps out of Okiedoodle.

He says, COOL, CLIMBING STONES!

Zoe and Felix follow Messy to the cave. Messy climbs over stones the dirty stones.

The cave whines, OOH, AH!
OW!

Felix yells, LOOK OUT, MESSY!

[Rumbling]

Messy jumps out of the cave.

Zoe says, IT'S A GIANT MOUTH!

[Cave groaning]

Messy says, IT'S GIGANT-ENORMOUS!

The cave says, OH, DEARY ME.

Felix says, UH, HELLO!
I'M FELIX, AND THIS IS ZOE AND
MESSY.
WHAT'S WRONG?

The cave says, HELLO, I'M ROCKY AND…
OW!
SORRY, MY TEETH ARE HURTING,
AND WHENEVER THEY HURT, I...

[Rumbling]

The ground shakes. Messy, Zoe and Felix stumble.

[Rocky, the cave, groaning]

Zoe taps her watch.

She says, COME IN, ZAM.
I THINK WE'VE FOUND WHERE THE
RUMBLES ARE COMING FROM.

In a video call, Zam says, GREAT WORK, WE'LL BE THERE
WITH YOU AS QUICK AS WE CAN.

In the jelly shop, a jelly runs past Zam.

Zam says, SOMEBODY GRAB THAT JELLY!

Zoe ends her call.

[Watch beeping]

Felix says, WE NEED TO FIND OUT WHAT'S
MAKING ROCKY'S TEETH HURT AND
STOP IT.

Rocky says, OH, IF YOU COULD, I'D BE MOST
GRATEFUL.

Zoe says, UH, LET'S HAVE A CLOSER LOOK.

She and Messy take a look at Rocky’s stone teeth. Felix reaches into his bag.

He says, I'VE GOT JUST THE THING.
A MAGNIFYING GLASS.

Felix looks at the green substance on Rocky’s teeth. The magnifying glass shows tiny green creatures having a picnic.

Zoe asks, WHAT ARE THESE FUNNY LITTLE
THINGS?

Rocky says, THEY'RE MOSS MUNCHERS.
THEY LOVE TO NIBBLE ON MOSS,
AND MY TEETH ARE COVERED IN
MOSS.

Felix says, UGH.
THE MOSS IS ALL STICKY.

Moss sticks to his hand.

Felix says, I THINK THE MOSS MUNCHERS ARE
STUCK.

Rocky says, AND WHEN THEY TRY AND
WRIGGLE FREE, THEY...

The ground shakes.

Rocky wails, OW!

[Rumbling]

[Messy, Zoe and Felix shouting]

Messy, Zoe and Felix stumble backward down the mountain.

Messy yells, GANG WAY!

He stumbles further down the mountain with a handful of moss. Zoom, as a hand, catches the three friends.

[Grunting]

Messy says, THAT WAS HANDY.
THANKS, ZOOM!

Zoom carries the friends back to the cave where they meet Zim and Zam.

Zim says, WE'D HAVE BEEN HERE SOONER,
BUT IT TAKES A SURPRISINGLY LONG
TIME TO NAIL DOWN JELLY.

Messy says, LOOK WHAT WE FOUND!

He shows Zim and Zim his handful of moss.

Zam says, GOODNESS, ARE THOSE MOSS
MUNCHERS?

Rocky groans, OWW!

[Rumbling]

Rocky says, SORRY.

Zoe says, WHEN THE MOSS MUNCHERS
WRIGGLE, IT MAKES ROCKY'S TEETH
HURT.

Zam says, A MOUNTAIN WITH TOOTHACHE.
NO WONDER IT'S CAUSING A FEW
RUMBLES!

Felix says, BUT HOW CAN SOMETHING AS
SMALL AS A MOSS MUNCHER HURT
SOMETHING AS BIG AS A MOUNTAIN?

Zam says, NOW, LOOK, THIS BIT OF TOOTH
HAS BROKEN OFF.

She shows the others a piece of broken rock covered in moss.

She says, LET'S EXAMINE IT IN THE LAB.
COME.

[Zoom beeping]

In the lab, the team examines the mossy tooth piece.

Zim says, ZOOM, X-RAY MODE, PLEASE.

Zoom transforms into a screen that shows an x-ray of the tooth piece with Zim and Zam on either side.

Felix says, THERE'S THE STICKY
MOSS!

Zam says, AND JUST LIKE YOUR
TEETH, ON THE OUTSIDE THEY'RE
HARD, BUT ON THE INSIDE...

Zim wiggles the inside of the tooth piece.

Felix says, WOW.
IT'S ALL SOFT AND GOOEY.

Zim says, EXACTLY.
THAT'S WHAT THE HARD BIT IS
THERE TO PROTECT.

Zoe says, THAT BIT'S NOT AS THICK.
THE ROCK'S BEEN WORN AWAY BY
MOSS MUNCHERS WRIGGLING.

The x-ray shows moss munchers in the tooth.

Messy says, YEAH, IT MAKES ROCKY GO ALL,
"OOH, AH, OW!"

[Rumbling]

The room shakes.

Everyone says, WHOA!

They stumble.

Zam says, MESSY'S RIGHT.
THE MOSS MUNCHERS MAKE ROCKY
RUMBLE WHEN THEY WRIGGLE.
THE SAME THING HAPPENS IN OUR
MOUTHS.

She points to Zoom’s screen. In a video, tiny creatures wiggle on dirty teeth. Zam scrubs a tooth with a toothbrush.

She explains, IF WE DON'T KEEP OUR TEETH CLEAN
A STICKY FILM CALLED PLAQUE
BUILDS UP, AND TINY CREATURES
CALLED BACTERIA MUNCH AWAY ON IT
AND YOUR TEETH START TO HURT,
LIKE ROCKY'S.

In the video, Zim carries a tube of toothpaste.

He says, AND AS WELL AS BRUSHING AND
WATER, WE USE TOOTHPASTE.

Zim squirts toothpaste on the dirty teeth. The tiny creatures leave the teeth. Zam continues brushing.

Zim adds, IT'S FULL OF SPECIAL INGREDIENTS
THAT HELP TO KEEP TEETH HEALTHY
AND CLEAN.

In the lab, Zoe says, AND THAT'S WHY WE NEED TO
CLEAN THE MUNCHERS OUT OF
ROCKY'S MOUTH.

[Rumbling]

The room shakes and the team stumbles.

Messy says, AND QUICKLY!
THAT WAS THE BIGGEST WOBBLE YET.

In Rocky’s mouth, the cave, Messy stands behind Rocky’s teeth.

He says, THIS JOB IS MESSY, STICKY AND
DISGUSTING.
I LOVE IT!

He throws a handful of moss to Zoe. Zoe frowns.

She says, WE SHOULD FIND SOMEWHERE TO
PUT THIS MOSS SO THE MOSS
MUNCHERS GET A NICE NEW HOME.

Zoe throws the moss to Felix, who stands beside a rock pool.

Felix says, THIS ROCK POOL WILL MAKE THE
PERFECT HOME FOR THEM.

He puts the moss on a rock in the pool.

Messy says, THERE YOU GO, MUNCHY LITTLE
MATES.

Zoe says, THAT'S THE MOSS MUNCHERS
SAFE.

The moss munchers relax on lounge chairs.

[Moss munchers chirping happily]

Zoe says, YOU'LL BE MUCH HAPPIER OVER
HERE.

[Felix chuckling]

Felix adds, AND ROCKY WILL BE HAPPIER, TOO.

Small amounts of moss remain between Rocky’s teeth.

Rocky sighs, AH...
THANK YOU, EVERYBODY.

Zam says, NOW WE JUST NEED TO MAKE SURE
THE MOSS MUNCHERS DON'T GO BACK
TO ROCKY'S TEETH.

Zim says, WHICH MEANS STOPPING THE MOSS
GROWING BACK.

Zoe says, WHICH MEANS WE NEED TO CLEAN
ROCKY'S TEETH.

She looks at Zoom.

She says, COME ON, LET'S GO.
ZOOM, WATER!

Zoom transforms into a hose and sucks water from the pond. Messy sprays the water at the moss on Rocky’s teeth.

[Rocky gargling]

Zoe orders, FELIX, BRUSH!

Felix pulls the brush out of his bag.

He says, CHECK!

Zoe orders, MESSY, TOOTHPASTE.

Messy says, GERONIMO!

He jumps on a giant tube of toothpaste. Toothpaste squirts out onto Rocky’s teeth. A mechanical arm from the cloud ship scrubs Rocky’s teeth with the brush.

Messy says, SCRUBBING OKIDOODLE HELPED GET
THE DIRT OFF, AND BRUSHING TEETH
HELPS GET THE DIRT OFF, TOO.

[Rocky chuckling]

Felix lassos one of Rocky’s teeth with a rope.

Rocky laughs, OH, THAT TICKLES!

Zoe and Felix jump up and down with the rope, flossing Rocky’s teeth. Later, Rocky’s teeth are clean of moss.

Zam says, WELL, IT LOOKS LIKE
EVERYBODY'S HAPPY.

Rocky says, THANK YOU.
I CAN'T REMEMBER THE LAST TIME
MY MOUTH FELT SO CLEAN.

Messy says, EVEN A MESSY MONSTER CAN
ENJOY SOME GOOD, CLEAN FUN.
BUT IT'S TIME FOR ME TO GO HOME
NOW.
BYE, EVERYONE.

Zoe and Felix say, BYE, MESSY!

They wave. Messy transports back to the bathroom onto the sink. He kneels beside a toothbrush and brushes his teeth. He smiles in the mirror.

He says, NOW I KNOW WHY I NEED TO USE
A BRUSH AND TOOTHPASTE.
TO CLEAN MY TEETH PROPERLY.

Messy licks his lips.

He says, MMM!
HERRING AND TURNIP FLAVOUR.
DELICIOUS!

End credits.

Messy sings, BA-LA-BA-LA-BOOM-BOOM!
