In animation, the camera pans into an attic.

Bitz and Bob come out of the trap door.

A song says BITZ and BOB,
BITZ and BOB, BITZ and BOB
AH, AH-AH, AH-AH

Bitz has brown hair and wears white and green striped stockings, a pink pleated skirt with a brown belt, a white shirt with a print, a denim jacket with pins, ping fingerless gloves and goggles over her head.

Bob is a little brown haired boy in a robot outfit.

The song continues HER NAME IS BITZ,
THE INVENTOR
STEAM PINK ADVENTURER
ENGINEER OR VISION KICKS
NOTHING THAT
THE GIRL CAN'T FIX
HER SUPER SIDEKICK,
BOX ROBOT OUTFIT
TOGETHER, THEY WILL FIX IT,
SO READY, SET, LET'S GO
WE CAN WORK IT OUT

They high five and grab some toys.

They grab their toys: a rag doll named Purl, an action figure called Bevel, a blue green stuffy named Zip and a pink stuffy named Big Pop.

They suddenly appear on a ship, riding a slate on a snow covered mountain, in a castle with friends, and riding their bikes on the street.

The song continues WHOA-WHOA-WHOA, WHOA-WHOA
AH, AH-AH, AH-AH
WE CAN WORK IT OUT
WE'LL INVENT A WAY
THROUGH IDEAS AND PLAY
BITZ and BOB
WILL SAVE THE DAY

The logo of the show appears. It reads "Bitz and Bob."

Bitz dots the "I" in "Bitz" with a cog.

The song says BITZ and BOB, BITZ and BOB,
BITZ AND BOB!

The name of the episode reads "A birthday surprise."

(HUMMING)

In the attic, Bitz puts Purl on her little hammock and rocks her.

(IMITATING ZOOMING)
(GIGGLING)

Bitz says HEY, BOB?
READY FOR THE BIG DAY?

Bob says HUH?

Bitz says YOU HAVEN'T FORGOTTEN.

She whispers in his ear.

(INDISTINCT WHISPERING)

Bob gasps and says IT'S PURL'S BIRTHDAY?!

Bitz says SHH!

She whispers WE'RE GOING TO
MAKE HER A SURPRISE PRESENT.

Bob says I LOVE SURPRISE PRESENTS.

Bitz says SO, UH, ANY IDEAS?

Bob whispers WHAT DO YOU
THINK?
HMM, A ROLLER SKATING DINOSAUR
TO RIDE ON!

Bitz says BUT PURL HAS HER OWN AWESOME
ROLLER SKATES ALREADY!

Bob says UM...
SHE LOVES SPARKLES.

Bitz says YES, BUT SHE'S ALREADY GOT A
SPARKLY TIARA.

Bob says UH, MAYBE A NEW HAIR CLIPPY
THINGY.

Bitz says YES, SHE'S ALWAYS LOSING
HERS.
GREAT IDEA, BOB.
LET'S MAKE HER ONE!

Bob says HOO, YEAH!

Bitz says ONE DAY, IN JUBILEE JUNGLE...
TOP-SECRET PLANS FOR PURL'S
BIRTHDAY SURPRISE WERE UNDERWAY.

In the jungle, Purl rocks on her hammock and sings HAPPY BIRTHDAY
DEAR ME...
(GIGGLING)
I CAN'T WAIT 'TIL EVERYONE GETS
HERE.
LA, LA, LA, LA, LA.

Everyone hides in the jungle.

Bitz says OUR MISSION IS TO MAKE PURL
AN AWESOME NEW BIRTHDAY
HAIRCLIP.

They all say OOH!

Bitz says OKAY, DESIGN TEAM, WE NEED
IDEAS.

Bob says PURL LOVES, UH, BRIGHT
COLOURS!
(SPEAKING GIBBERISH)

Bitz says OKAY, SO, BRIGHT COLOURS.

Bevel puts a leave over one eye and says OH, HOW ABOUT A JUNGLE VIBE?
OH.

Bob says NICE, BUT IT NEEDS TO BE MORE
GRIP-ILY.

Bitz says OH, YES.
A HAIRCLIP THAT DOESN'T GRIP IS
NO USE, AND IT HAS TO BE SUPER
GLITZY FOR PURL.
I KNOW!
I'LL TAKE HER ON A WALK TO FIND
OUT EXACTLY WHAT JUNGLE-Y THINGS
SHE LOVES.

Bob says GOOD IDEA!
(SPEAKING GIBBERISH)

Bitz says OKAY, YOU FOLLOW SECRETLY
BEHIND US AND COLLECT THE THINGS
SHE SAYS SHE LIKES.
OH, AND COLLECT ANYTHING ELSE
YOU THINK MIGHT BE USEFUL, LOTS
OF IT.

Bevel says ALL RIGHT!

Bob says OH, YEAH.

Bitz says AND REMEMBER, IT'S A
SURPRISE, SO DON'T LET HER SEE
YOU.

Bevel says GOT IT.

Bob says OKAY.
(HUMMING)

Bitz says PURL!

Purl says OH, BITZ!

Bitz says HEY, BESTIE.

They do a cool handshake.

(GIGGLING)

Purl says TODAY IS A VERY SPECIAL DAY.
IT'S...

Bitz says A PERFECT DAY FOR A NATURE
WALK.

Purl says OH!

Bitz says LET'S GO.

Purl says OH, GREAT IDEA, BUT LET'S
WAIT FOR THE OTHERS?

Bitz says OH, UH...

They all hide in the bushes and giggle.

(GIGGLING)

Bevel says SHH!

Bitz says THEY'RE TOO, UH, BUSY.
UH, BEVEL'S HAVING...
HIS FUR COMBED.

Purl says UH, OH MY!

Bitz says THIS WALK'S FOR BESTIES ONLY.

Purl says OH!

Bitz says COME ON.

Bob says LET'S DO THIS!

Purl says OOH!
(GASPING)

Purl says LOOK AT THIS GORGEOUS LEAF!

Bitz says HMM.

Purl says OOH, WHOA!
AND THIS FABULOUS FLOWER!
(GASPING)

Bitz says PSST!

Purl says THESE ARE SO PRETTY!

Bitz says WELCOME, EVERYONE, TO BITZ
TV.
(GIGGLING)

Purl says OH, MY.

Bitz says WE'RE HERE TODAY WITH
SUPER-STYLE EXPERT, AND MY
BESTIE, PURL.
CAN YOU TELL THE AUDIENCE
EXACTLY WHAT YOU LOVE ABOUT THAT
FLOWER?

Purl says OH, AHEM, WELL, IT'S SO
COLOURFUL, AND IT'S SO SOFT AND
SILKY!
BUT MY FAVOURITE THING ABOUT IT
IS...
(SNIFFING)
THAT IT SMELLS DE-LOVELY!

Bevel says AH!

Bob smells another flower and says WHOO.
HMM.

He says UH-OH!
(SNEEZING)
(GASPING)
(GROANING)

Purl looks over Bitz's shoulder and says WHAT'S T...

Bitz says YAY, DID YOU HEAR THAT,
AUDIENCE?
PURL LOVES FLOWER SMELLS!

Bob says WHEW, THAT WAS CLOSE.

Bevel says OKAY, PURL LIKES, UH, SMELLS,
GOT IT.

Purl says I'M VERY EXCITED TO ANNOUNCE
TO THE BITZ TV VIEWERS THAT
TODAY IS A VERY SPECIAL DAY.
IT'S...

Bitz says TIME FOR A NEWSFLASH!

Purl says OH!

Bitz says WE NEED TO HEAD OVER
THERE.

Purl says to herself IT'S MY BIRTHDAY.

Bitz says LOVELY FLOWER SMELLS, GOT IT.
(GASPING)
PURL!

Purl says HUH?

Bitz says I FOUND SOME LOVELY APRICOTS!

Bevel says OOH!
(CHUCKLING)

Purl skates in circles.

(IMITATING WHOOSHING)
(GASPING)

Purl picks up an apricot and says WOW, SO SOFT AND FURRY AND
VELVETY, AND APRICOTS MAKE
APRIL-ICIOUS CAKES FOR VERY
SPECIAL OCCASIONS!

Bitz says LIKE, UH, BREAKFAST MUFFINS!

Purl says OH.

Bitz says LET'S COLLECT SOME.

Purl says I MEANT FOR BIRTHDAY CAKES.

Bitz takes notes and says SOFTNESS.
LOVES APRICOT CAKES.
(RUSTLING)
HUH?

She approaches Zip and Big Pop, who are goofing around in the bushes.

(SPEAKING GIBBERISH)

Bitz says UM, SHH!

Big Pop gets tangled in a vine.

Bitz says WHOOPS!
HMM.
CURLY VINE TANGLES, GOOD GRIP.

Purl says OH, WHAT WAS THAT?!

Bitz says UH, UM, IT WAS JUST A BUZZY
FLY.
(IMITATING BUZZING)

Purl says UH, OKAY.
(GASPING)

Bitz says OOH!

Purl says LOOK, BITZ, A BUTTERFLY!

Bitz says WOW!

Purl says ISN'T IT JUST THE PRETTIEST
THING IN THE WHOLE JUNGLE?

Bitz says OH, LET'S FOLLOW IT!

Purl says YES, LET'S!

Bitz takes notes and says PRETTY BUTTERFLY.
(GIGGLING)
(HUMMING)

Bevel says HEY, BOBSTER!
BITZ SAID PURL LIKES SMELLY
THINGS.

Bevel holds a dirty sock in front on his nose.

Bob says PHEW-EE!

Purl says OOH, OH, IT'S SO MUCH FUN
BEING A BEAUTIFUL BLUE
BUTTERFLY!

The butterfly flies past Bevel and Bob.

Bevel says UH...

Purl says HEY, BOB?
(HUMMING)

Purl says OH, HI, PURL!
HI, BITZ.

Bevel says NICE DAY FOR A WALK.

Purl says OH, HELLO!
(GIGGLING)

Big Pop and Zip approach carrying leaves and twigs.

Bevel stops them.

(RUSTLING)

They hide the leaves and twigs in the bushes.

(SPEAKING GIBBERISH)
(CLEARING THROAT)

Zip and Big Pop say HUH?

Purl turns around and says HOW LOVELY TO SEE YOU ALL!
WELL, NOW THAT WE'RE ALL
TOGETHER, WE CAN FINALLY
CELEBRATE THIS VERY SPECIAL DAY.
IT'S...

Bitz says BEVEL'S FUR-COMBING DAY.

Bevel says OOH, THE BEVELMEISTER DOES
LOVE A GOOD PAMPER.

Bitz says THANKS FOR THE LOVELY WALK,
PURL.
WE CAN HANDLE THOSE KNOTTY FUR
BALLS BY OURSELVES.

Bob says BYE-BYE.

Bitz says SEE YOU LATER.

Purl says BUT-- BUT IT'S MY VERY
SPECIAL...
BIRTHDAY.
(SIGHING)

She lies on her hammock.

Bitz says PURL THINKS WE'VE REALLY
FORGOTTEN HER BIRTHDAY.
WE'VE GOT TO MAKE HER NEW
HAIRCLIP SUPER-FAST!
WHAT DID YOU FIND, DESIGN TEAM?

Zip and Big Pop say TA-DA!

They show her a pile of leaves, twigs, vines, flowers and apricots.

Bitz says WOW.
THERE'S SO MUCH STUFF HERE!

Bevel says AND THE BEVELMEISTER FOUND
THE PERFECT THING!

He takes out the sock and says TA-DA!
(ALL GROANING)

Bitz says PHEW.
I'M NOT SURE A SMELLY SOCK
HAIRCLIP IS QUITE PURL'S STYLE.

Bevel says REALLY?
OH, YEAH, TOTALLY KNEW THAT.

Bitz says BUT IT IS A COOL BLUE.

Bob says JUST LIKE THAT FLUTTERBY SHE
LOVED!
(GASPING)

Bitz says THAT'S IT!
WE NEED TO PICK THINGS FROM THIS
BIG PILE OF STUFF THAT WE KNOW
PURL REALLY LIKES.
IT'S TIME FOR A BITZ BRAIN
BLITZ!
WE FOUND LOTS OF THINGS FOR
PURL'S HAIRCLIP.
SOME MIGHT BE USEFUL, AND SOME
MIGHT NOT BE, BUT THEY CAN GIVE
US GOOD IDEAS.
TO HELP US CHOOSE, WE CAN USE MY
NOTES TO REMIND US OF PURL'S
FAVOURITE THINGS.
WE WANTED TO MAKE SOMETHING
BRIGHTLY-COLOURED AND JUNGLE-Y.
PURL LIKES THINGS THAT ARE SOFT
AND SMELL LOVELY.
AND WE NEED SOMETHING THAT GRIPS
WELL.
AND WE CAN MAKE IT IN THE SHAPE
OF SOMETHING REALLY PRETTY, LIKE
THE BUTTERFLY.
A PERFECT HAIRCLIP DESIGN, AND
PURL WILL LOVE IT, AS IT'S MADE
USING ALL HER OWN IDEAS.
THAT'S IT!
STEAM PINK STYLE!

They all say LET'S GET BUSY!

Bevel says OOH, HERE'S THE GRIP-ILY BIT!

Big Pop says BOB!

Bitz says RIGHT.

Bob gives Bitz a flower and says HERE.

Bitz says HMM, THANKS.
AND WE CAN STICK ON THESE SOFT,
COLOURFUL PETALS IN THE SHAPE OF
WINGS TO MAKE...
A BEAUTIFUL BUTTERFLY HAIRCLIP!

They all say OOH, YEAH!
(CHEERING)

Meanwhile on her hammock, Purl sings sadly HAPPY
BIRTHDAY TO ME...

They all approach her and shout HAPPY BIRTHDAY TO PURL!
SURPRISE!

Purl says OH, MY SHINY SEQUINS!

Bitz says AS IT'S A VERY SPECIAL DAY,
WE MADE YOU A VERY SPECIAL
PRESENT!

Purl says OH!

Bitz says TA-DA!

Purl says A BUTTERFLY?
WITH SOFT WINGS MADE FROM
PETALS?

Bitz says AND A CURLY VINE CLIP!

Purl says MM!
AND IT SMELLS LOVELY!
THANK YOU!

Bitz says YOU DIDN'T REALLY THINK WE'D
FORGOTTEN YOUR BIRTHDAY, DID
YOU, BESTIE?

Purl says AWW, THANKS, BITZ.

They hug.

Everyone says TA-DA!
(CHEERING)

Purl says APRICOT CAKE, MY FAVOURITE!

The butterfly lands on Bevel's face.

Bevel says HEY, THAT TICKLES!
DON'T MESS UP THE BEVELMEISTER'S
FUR!
(GIGGLING)
(GIGGLING)

Back in the attic, Bitz says I LOVE BIRTHDAYS.

Bob says ME TOO, AND I'VE JUST
REMEMBERED, IT'S BEVEL'S
BIRTHDAY TOMORROW.
AND ZIP AND POP'S BIRTHDAY THE
DAY AFTER.
AND IT'S MY BIRTHDAY THE DAY
AFTER THAT.

Bitz says DON'T FORGET MINE.
THAT'S A LOT OF BIRTHDAY
SURPRISES TO PLAN.

Bob says AND BIRTHDAY CAKES TO BAKE.

Bitz says AND EAT!

Bob says MM-MM!

Bitz says NOM, NOM!

They pretend to eat plastic cakes.
