Remote controlled vehicles with googly eyes drive around a forest, doing all types of activities.

Lily is a purple monster truck, Zack is a red monster truck, Axle is a blue race car and Rex is a yellow dump truck.

A song says ZERBY DERBY!
ZERBY DERBY!
RACE! DIG!
BUILD! PLAY!
IT'S ZERBY DERBY!

The name of the show appears in letters with a wheel track pattern.

(music plays)

The name of the episode reads "You’ve Got Some Splaining To Do. Written by Naomi Jardine."

Zack sings MY WHEELS ARE GREAT!
WITHOUT MY WHEELS
I'D BE A SLED

Zack says HEY, THERE'S A LITTLE,
BABY TREE IN THE MIDDLE
OF THE TRAIL HERE. THAT'S OKAY.
I CAN SWERVE AROUND YOU,
LIKE THIS.

(MAKES ZOOMING SOUND)
(LAUGHS)

Zack says HEY, IF THERE WAS SOMETHING ELSE
TO SWERVE AROUND THIS WAY,
AND THEN SOMETHING ELSE TO
SWERVE AROUND THAT WAY,
WE COULD MAKE A FUN OBSTACLE
COURSE! (GASPS)
I'M GOING TO GO GET REX AND
STRUT! OH, WOW! THIS IS A
GREAT IDEA, BABY TREE! (LAUGHS)
(MAKES ZOOMING SOUND)

(music plays)

Zack says WE COULD PUT STICKS ALL
ALONG THE TRAIL, AND SWERVE
AROUND THEM! (LAUGHS)
SWERVE, SWERVE, WHOA!

He flips over and says THAT'S TOO MUCH SWERVING.
(LAUGHS)

(music plays)

Zack says REX, STRUT, I HAVE THIS
IDEA WHERE WE SWERVE AROUND
STICKS! IT'S GOING TO BE THE
BEST OBSTACLE COURSE EVER!
IT'S BY THE BABY TREE!

Rex says UH, WHAT WAS THAT ABOUT?

Strut says I DON'T KNOW.

Rex says DOES HE WANT US TO FOLLOW
HIM?

Strut says HE DIDN'T SAY.

Zack says COME ON, ZERBIES! I NEED
YOUR HELP! WE HAVE TO GO!
YOU'VE GOT TO BUILD IT!

Rex says UH, I GUESS SO! WHAT ARE WE
DOING, ZACK?

(music plays)

Zack says THIS IS GOING TO BE GREAT!
OKAY, YOU SEE THIS LITTLE, BABY
TREE RIGHT HERE? DO YOU SEE IT?
IT'S THIS ONE. THE ONE RIGHT
HERE.

Rex says YEAH.

Strut says UH, YES. IT'S UH, RIGHT
IN THE MIDDLE OF THE TRAIL.
DO YOU WANT US TO MOVE IT?

Zack says NO, NO, NO, NO, BECAUSE
SWERVING AROUND IT IS FUN.

Rex says OH. OKAY, SO THE TREE
STAYS?

Zack says YEAH, THAT'S RIGHT.
YOU SEE, WHAT WE COULD DO IS
WE GET MORE TREES, EXCEPT
THEY'RE NOT TREES, THEY'RE
STICKS, AND THEN WE COULD SWERVE
AROUND THEM LIKE
(MAKES ZOOMING SOUND)
VROOM! I CAN SEE IT ALL
PERFECTLY IN MY HEAD. SO IF YOU
ZERBIES GET STICKS AND MAKE IT,
I CAN GET AXLE!

Strut says OKAY.

Zack says OKAY!

Strut says SO TELL US HOW YOU WANT
THE STICKS, AND WE'LL GET -

Rex says TOO LATE. HE'S GONE.

(music plays)

Zack laughs and says NOW WE NEED TO
FIND AXLE. I THINK THE LAST TIME
I SAW HIM HE WAS IN WHOA! ZERBY
TOWN! ZERBY TOWN. HEY, UH-OH.
CAREFUL. CAREFUL, ZACK, DON'T
FALL. OKAY, GOOD. YEAH.
HE WAS IN ZERBY TOWN, SO I'LL GO
FIND HIM IN ZERBY TOWN,
AND WE'LL GET BACK, AND THE
WHOLE RACE COURSE WILL BE
FINISHED!

(music plays)

At Axle’s garage, Zack says AXLE, COME QUICK!

Axle says OH, HI, ZACK. WHAT'S GOING
ON?

Zack says OH, ARE YOU CHARGING?

Axle says YEAH, I NEED A FEW MORE
MINUTES.

Zack says WELL, WHEN YOU'RE DONE, I
HAVE SOMETHING TO SHOW YOU!

Axle says WHAT?

Zack says IT'S THE BEST OBSTACLE
COURSE EVER.

Axle says WHOA, THAT SOUNDS FUN! UH,
WHERE IS IT?

Zack says WE'RE BUILDING IT.
I KNEW EXACTLY WHAT I WANTED
IN MY HEAD.

Axle says WOW!

Zack says I'LL COME GET YOU WHEN
IT'S FINISHED! BYE, AXLE!

(music plays)

Zack says WELL, REX AND STRUT MUST
HAVE FINISHED BUILDING IT
BY NOW, SO I'LL GO TEST IT OUT,
AND THEN I'LL COME BACK,
AND THEN I'LL GET - WHOA! HEY, I
LANDED BACK ON MY WHEELS!
(LAUGHS)

(music plays)

Zack says HI, ZERBIES. AXLE'S GOING
TO COME AS SOON AS HE CHARGES -
WHERE'S THE COURSE?

Strut says RIGHT HERE.

Rex says IS THIS WHAT YOU WERE
THINKING, ZACK?

Zack says WELL, IT'S NOT WHAT I HAD
IN MY HEAD. I GUESS I NEED TO
EXPLAIN IT BETTER. I GUESS I
SHOULD ADD DETAILS.
OKAY, WHAT YOU WANT TO DO IS
STICK THE STICKS SO THE STICKS
ARE STICKING UP. BUT INSTEAD OF
STICKING THE STICKS TOGETHER,
YOU STICK THE STICKS STICKING UP
A STICK LENGTH FROM EACH
OTHER STICK. YOU GET IT?

Strut says UM...

Zack says OKAY!

Rex says I GET THAT THE STICKS ARE
STICKING UP, AND THEY'RE
SPACED OUT.

Strut says RIGHT.

Zack says OKAY, GOOD LUCK, ZERBIES!
YOU... OH, HE'S GONE AGAIN.

Axle says I'M WAITING FOR THE
CHARGE TO FINISH

Zack says AXLE! AXLE! ARE YOU DONE
CHARGING?

Axle says OH, YEAH, YEAH! JUST
FINISHED.

Zack says OKAY, LET'S GO!

(music plays)

Zack says THIS IS GOING TO BE SO
GREAT!

Axle says OKAY, WHERE IS IT?

Zack says IT'S OVER HERE. WHOA!

Axle says HEY, ZACK.

Zack says HEY, HOLD ON. I NEED TO
FLIP OVER. YAHOO!
OH, THAT DIDN'T WORK.

Axle says THAT WAS A GOOD MOVE.
OKAY, DO YOU NEED HELP?
I'LL HELP YOU. OKAY.

Zack says HEY!

Axle says OKAY, LET'S GO!

Zack says OKAY, LET'S GO! YEAH!

Axle says WHICH WAY IS IT?

Zack says IT'S THIS WAY.

(music plays)

Zack says OKAY, AXLE, YOU'RE GOING
TO LOVE THIS RACE COURSE.
IT'S GOING TO BE SO AMAZING, AND
UH - HEY. WHAT IS THIS?

Rex says THIS IS IT!

Strut says YEAH, WE SPACED OUT THE
STICKS JUST LIKE YOU SAID.

Axle says UM, HOW DOES THIS RACE
COURSE WORK, ZACK?
WHICH WAY ARE YOU SUPPOSED TO GO
THROUGH ALL THESE STICKS?

Zack says WELL, THIS ISN'T REALLY
WHAT I HAD IN MY HEAD.
IT'S NOT QUITE RIGHT.

Strut says OH, ALL RIGHT. WELL, DO
YOU NEED MORE STICKS?

Zack says NO, IT'S NOT THAT.
IT'S JUST, THEY'RE SCATTERED ALL
OVER THE PLACE. WHY DIDN'T YOU
BUILD IT LIKE I SAID?

Rex says WELL, YOU SAID "STICK" A
LOT OF TIMES, AND IT WAS KIND OF
CONFUSING.

Strut says YES, IT WAS.

Rex says AND THEN YOU LEFT BEFORE WE
COULD ASK ANY QUESTIONS.

Zack says OH, YEAH. OKAY. YOU'RE
RIGHT.

Axle says OH, IT'S OKAY, ZACK. WHY
DON'T YOU TRY, TRY AGAIN?

Zack says OKAY. I'M GOING TO TRY,
TRY AGAIN, AND EXPLAIN IT
CLEARLY, AND I'LL WAIT TO SEE IF
YOU HAVE ANY QUESTIONS.

Strut says RIGHT. WELL, TRY
DESCRIBING WHAT YOU SEE IN
YOUR HEAD AS CLEARLY AS YOU CAN.

Zack says ALL RIGHT, WHAT I'M
THINKING IS WE NEED TO PUT THE
STICKS IN ONE STRAIGHT LINE,
LIKE ALL THE WAY DOWN THE TRAIL.
SO WE HAVE ENOUGH SPACE, WE
CAN DRIVE IN BETWEEN THEM.
LIKE THIS. AND THEN WE SWERVE
AROUND THIS WAY, AND THEN WE
SWERVE AROUND THE OTHER WAY,
AND THEN BACK AND FORTH,
ALL THE WAY ALONG. DO YOU SEE
WHAT I MEAN?

Rex says OH, I GET IT NOW!

Strut says OH, SO YOU'RE SAYING YOU
WANT THEM ALL SPACED OUT
IN A LINE.

Zack says YEAH, YEAH, EXACTLY!

Axle says THIS IS GOING TO BE FUN!
I CAN'T WAIT TO TRY IT!

Strut says GIVE US A FEW MINUTES TO
BUILD IT.

Axle says SWERVE!
I'M
PRACTICING MY SWERVE. SWERVE!

Zack says YOU'RE GOOD!

Axle says SWERVE!

Zack says DO YOU THINK IT'S READY?

Axle says LET'S GO CHECK!

Zack says YEAH, COME ON! LET'S GO!

Axle says SWERVE! LOOK AT ME
SWERVING! OH.
I DIDN'T SWERVE THERE.

Zack says COME ON, AXLE!

Axle says HEY, I'M COMING!

(music plays)

Zack says IS IT ALL DONE?

Strut says YES! IT'S ALL DONE!

Rex says I THINK WE GOT IT THIS
TIME!

Zack says LET'S TAKE A LOOK. OKAY,
SO THERE'S A STICK, THEN THERE'S
A GAP, AND THEN THERE'S ANOTHER
STICK. THAT'S GOOD.
AND THEN THERE'S ANOTHER GAP,
AND ANOTHER STICK. THAT'S GOOD.
AND THEN ANOTHER GAP, AND
ANOTHER STICK, AND ANOTHER
GAP AND A LITTLE, BABY TREE!
YOU DID IT! THIS IS EXACTLY WHAT
I HAD IN MY HEAD!

Strut says I THOUGHT SO.

Rex says YEAH, ME TOO. YOU EXPLAINED
IT SO WELL, WE KNEW EXACTLY HOW
TO BUILD IT.

Axle says YEAH! THE ONLY THING LEFT
TO DO IS TO TRY IT OUT.

Zack says HOT-DIGGETY-HUBCAPS!
LET'S GO! READY, SET, TURBO!
I'M GOING TO GO THIS WAY, AND
THEN I'LL GO THAT WAY,
AND THEN I'LL TURN THIS WAY, AND
THAT WAY, AND LITTLE, BABY TREE!

Axle says READY, SET, TURBO!
(LAUGHS)

Rex says GO, AXLE!

Axle says I SWERVE, SWERVE! (LAUGHS)
SWERVE! I'M A GOOD SWERVER!
(LAUGHS)

Zack says HEY, AXLE, THAT WAS GREAT!
WAY TO GO!

Rex says NICE DRIVING THERE,
ZERBIES!

Axle says HEY, CONSTRUCTION ZERBIES,
WHY DON'T YOU GIVE IT A TRY?

Rex says OH, I DON'T USUALLY DO
OBSTACLE COURSES.
ALL RIGHT. READY, SET, TURBO!
OH, I HIT THAT STICK THERE.

Zack says YOU'RE SUPPOSED TO GO
AROUND THE STICKS.

Rex says OKAY, I'M GOING AROUND.
OOH! I HIT THIS STICK, TOO.
(LAUGHS)

Strut says MAYBE YOU SHOULD TRY FROM
THE BEGINNING AGAIN.

Rex says OKAY. READY, SET, TURBO!
(BOING)

Rex says AM I SUPPOSED TO HIT THE
STICKS?

Zack says NO, YOU'RE SUPPOSED TO GO
AROUND THE STICKS.

Rex says OKAY, OKAY, I'M GOING TO GO
BACK UP AND GET A GOOD RUN
AT IT.

Axle says OKAY.

Zack says OKAY.

Rex says OKAY, HERE I COME! HERE I
COME, AND - LIKE THIS?

Zack says NO, NOT EXACTLY. YOU GO
AROUND THEM.

Rex says OKAY, I'M GOING TO TRY
AGAIN AND OH! NOW I'M STUCK
ON THE STICK. I NEED MORE
PRACTICE.

Axle says YEAH, YOU DO.

Zack says YOU MIGHT NEED TO TRY, TRY
AGAIN, REX.

(music plays)

The end credits roll as a gag reel plays.

Rex says OKAY, ZACK, EXPLAIN.

Zack says OKAY, IS THIS TOO CLOSE?

Strut says UH, A LITTLE TOO CLOSE.

(music plays)

Zack says OKAY, WHERE ARE WE GO -

He flips and says OH, I DIDN'T MAKE IT!

Rex climbs up the stick and says OKAY, HERE. ARE YOU SURE IT
ISN'T UP THE STICK?

Axle and Zack says NO!

Zack flips.

Rex says OKAY, I'M GOING TO GO FIND
ZACK.

Strut says ARE YOU SURE?

Rex says REALLY, I AM.

Zack flips and says WHOA!

(music plays)

ZACK FLIPS AGAIN AND SAYS WHOA!

REX SAYS I THINK I'M OFF COURSE!

(music plays)

Zack says LITTLE, BABY TREE!

Rex says HEY, HERE WE GO! OH, REX
THE PINBALL MACHINE.
