Lucas is in his twenties, with short puffy brown hair and wears jeans and an orange T-shirt.

Laura is in her twenties, with above the shoulders straight brown hair with bangs and wears jeans and a purple T-shirt.

As a song plays, Lucas and Laura walk in the woods, cross a bridge, balance on a fallen tree trunk, cross a stream, run across the city and in a park full of geese. Fast clips show them next to Greg playing and having fun in the tree fort. Greg is in his twenties, with short black hair. He wears a blue sweater.

The song says PACK UP YOUR BAGS KISS YOUR TURTLE GOOD-BYE COME UP AND CLIMB WHERE WE CAN TOUCH THE SKY SO MUCH TO SEE SO MUCH TO DO IN OUR TREE FORT WE'VE GOT A SHOW FOR YOU THAT TVOkids SHOW THAT TVOkids SHOW THAT TVOkids SHOW THAT TVOkids SHOW.

[Greg shrieking]

Laura says PASSWORD, PLEASE.

The word "PASSWORD" appears in the sky.

In animation, a dialogue bubble pops out of a map with the title of the show: "That TVO Kids Show."

The song continues LA, LA, LA, DO, DO, DO, BLAH, BLAH, BLAH THAT TVOKIDS SHOW! THAT TVOkids SHOW.

Inside the tree fort, Lucas stands in the forefront wearing a red hoodie as Greg stands in the background operating a complicated machine. Greg wears a red flannel shirt.

Lucas says ARE WE THERE YET?

Greg says LUCAS I DON'T KNOW IF DOCTOR DIPPY'S DEVICE TELEPORTATION DEVICE IS GOING TO WORK IT'S REALLY COMPLICATED I DON'T KNOW IF THIS UNDERWATER EXECURSION IS GOING TO HAPPEN.

Lucas says WE NEED TOGETHER THAT WAS OUR WHOLE PLAN FOR THE DAY GREG. DID YOU TURN IT ON AND OFF?

Greg says OF COURSE I DID. YES.

Lucas says IS IT THE BATTERY? BATTERY'S FINE. WHAT ABOUT THE MANUAL? I THOUGHT THERE WAS MANUAL?

Greg says NO MANUAL. HE THOUGHT WAS MAKING AN AIR CONDITIONER! BUT HE MADE A TELEPORTATION DEVICE UM... DID YOU TRY... HITTING IT WITH YOUR ELBOW?

Greg says I HAVN'T TRIED THAT.

He hits the machine with his elbow, then says IT DIDN'T WORK.

Lucas says OH, NO. OKAY, TRY A HAMMER, YEAH...

Greg says TRY A HAMMER. HERE WE GO.

Greg lifts up a hammer...

[FROGHORN]

[FROGHORN]

He puts down the hammer.

[FROGHORN]

[FROGHORN]

He takes the call and says WHO'S THIS?

A voice says HENRY.

Greg says DO YOU HAVE THE PASSWORD FOR TODAY?

Henry says Snorkel.

Henry appears in the sky.
A caption reads "Henry. Age 11."

Greg says SNORKLE, VERY IMPORTANT DEVICE. WELCOME TO THE TREE FORT. HENRY, AWESOME TO HAVE YOU. WE'RE TRYING TO GET UNDERWATER RIGHT NOW. WE WANT TO KNOW, WHAT WOULD YOU DO IF YOU WERE UNDERWATER FOR A DAY?

Henry says I'M I'D PROBABLY EXPLORE ALL THE CORAL AND STUFF.

Greg says YEAH, LOTS OF SIGHTS TO SEE, LOTS OF FISHES...

Lucas says LOTS OF SHARKS.

Greg says Which is your favourite species of shark and why?

Henry says THE GREAT WHITE SHARK IS THE BIGGEST AND STRONGEST.

Greg says AND IT'S THE BIGGEST FISH IN THE OCEAN.

Lucas says YEAH, THAT'S TRUE.

Greg says WHAT SHOULD WE DO? IN CASE YOU RUN INTO A SHARK? OKAY. HELP HENRY.

Henry's video freezes, then disappears.

Lucas says OKAY, YOU COULD PRETEND YOU'RE A WHILE WHALE.

Greg says YEAH... A WHALE. WOULDN'T IT BE EXCITING TO SWIM WITH ALL THE FISH, AND WHAT IF WE SEE A WHALE?

Lucas says DON'T WORRY, I SPEAK WHALE...

(SPEAKS GIBBERISH)

Lucas says YYOOOUUUUU TYYYAAAAOOONNN SSSWWOOOMMMMNN WWWIII MMMUUIII. WE LOST HENRY.

Greg says THAT'S UNFORTUNATE. BUT WE HAVE VIDEOS TO LOOK AT. SHOULD WE JUST CHECK THOSE OUT FOR NOW?

Lucas says OKAY, HENRY IS BACK, HERE WE GO. WELCOME BACK, HENRY.

Henry says HI...

Lucas says HENRY.

A voice says CHAMPION!

A short video shows Greg's orange and white cat sleeping as it moves its fur.

Greg says HENRY, HE IS HAVING DREAM. WHAT DO YOU THINK ABOUT MY CAT?

[LAUGHTER]

Henry says I LIKE THEM. THEY'RE FUN.

Lucas says YEAH. FOR SURE. WHAT WOULD YOU RATE IT OUT OF TEN?

Henry says AN EIGHT.

Greg says OKAY, YES. I'LL TELL PEACHES AND CREAM THAT OKAY, CHECK OUT OUR CHALLENGER. HERE IT IS.

A voice says Challenger!

A short video shows a striped blue and yellow fish.

Greg says OKAY. THIS IS A coffer FISH. SO THEY BALLOON UP INSIDE. WHAT DID YOU THINK ABOUT THAT, HENRY?

Henry says 7.

Lucas says SAY THAT AGAIN?

Henry says A 7.

Lucas says A 7? THAT'S OKAY, TOO. I LOVE IT. HENRY, THANKS FOR YOUR HELP TODAY. YOU CAN OBVIOUSLY CALL BACK AT ANY TIME. GOOD LUCK OUT THERE WITH THE GREAT WHITE SHARKS.

Greg says BYE, HENRY. THANK YOU SO MUCH.

[APPLAUSE]

[Chime]

Lucas says WHAT WAS THAT? IS THAT AN EMAIL?

Greg says YES, IT IS AND WHICH MEANS IT IS TIME FOR...

In animation, a megaphone pops up and the tree fort shakes as a voice yells We need to know!

Lucas says OKAY. THAT MEANS WE HAVE A A QUESTION THAT WE NEED TO ANSWER.

Greg says FROM STEVE, AGE 5. WHY IS SOME WATER TURQUOISE AND SOME WATER BROWN?

Lucas says EVEN LAKES IN ONTARIO, SOME ARE BROWN, SOME ARE BLUE. WHY?

Greg says WE LOOKED IT UP WITH WALTER THE SCIENTIST.

A clip plays in which Walter the Scientists stands at a table inside a lab. He has short dark hair and wears glasses and a white lab coat.

He says GREAT QUESTION. IT'S SIMILAR TO WHY THE SKY IS BLUE. HAVE YOU SOME LIGHT IN THE SKY AND YOU END UP WITH A BLUE COLOR EVERYWHERE. THE SAME THINGS HAPPENS WITH WATER. WATER IS ACTUALLY PERFECTLY CLEAR. BUT OVER A LONG STANCE, IT HAS THAT SCATTERING EFFECT, BUT ALSO WATER, IT LIKES TO HAVE FRIENDS ALONG ITS JOURNEY. SO AS IT TRAVELS ALONG IT PICKS UP DIFFERENT MINERALS AND DIRT AROUND IT, SO IT MAY CHANGE COLOR. AND IT'S VERY REFLECTIVE. SO SOMETIMES IT REFLECTS THE COLOR OF THE ENVIRONMENT AROUND IT, BEAUTIFUL BLUE SKY, BEAUTIFUL BLUE WATER.

The clip ends.

Greg says LUKE A I HAD TO RECONFIGURE THE TRANSISTORS IN THE MOTHER BOARD. THERE YOU GO. YOU READY?

Lucas says I DON'T KNOW. WE MADE IT.

Greg pulls a lever on the device and the tree fort starts to spin increasingly fast. Both friends hang onto the wooden railings.
As the fort stops, it sits under the sea next to a coral reef teeming with fish. Lucas disappears.

Greg looks around and says LOOK AT ALL THOSE FISH AND AT WATER. LUCAS, ARE YOU SEEING IT? LUCAS? HEY, TVOKIDS, DID YOU SEE LUCAS? HE FLEW OFF THE TREE FORT? OH, OKAY. THAT'S NOT GOOD. WHERE IS MY SCUBA SUIT?

In the water, Lucas is dressed in a full turtle suit.

He says IT'S A BEAUTIFUL DAY HERE IN THE OCEAN, I'm Mister TURTLE.

Greg says LUCAS.

Turtle says IT'S ME MR. TURTLE I AM 79 YEARS OLD, BUT MY SPECIES HAS BEEN AROUND FOR MORE THAN 200 MILLION YEARS, WE DATE BACK TO THE TIME OF DINOSAURS.

Greg swims up to him and says OH THAT'S INTERESTING. BUT COULD YOU HELP ME FIND MY FRIEND LUCAS, PLEAASSEEEE?

Turtle says I HAVEN'T SEEN HIM, NO. TURTLE FACTS: TURTLES HAVE A COMPASS IN THEIR BRAINS AND CAN DETECT EARTH'S MAGNETIC FIELD. THEY CAN COME BACK TO THE SAME SPOT WHERE THEY FIRST STARTED. TURTLES HAVE A SHELL, A SUPER-TOUGH CASING THAT ACTS LIKE A SHIELD TO PROTECT THEM FROM PREDATORS.

Greg says HAVE YOU SEEN HIM? BLACK HAIR.

Turtle says NO. THE SHELL IS MADE UP OF 50 BONES INCLUDING ITS RIB CAGE AND THE SPINE. SOME TURTLES ARE HERBIVORES, SOME ARE CARNIVORES AND SOME ARE OMNIVORES.

Greg says JUST POINT ME THAT DIRECTION, ANY WAY.

Turtle says TURTLES ARE COLD BLOODED CREATURES. SEA TURTLES CAN SWIM UP TO 14,500 KM.

Greg says UGH, THIS IS NOT HELPING ME, MR. TURTLE. PLEASE GIVE ME A SOLUTION! NOOOOO.

Turtle says SHARK? HUH! NEVER, SHARKS WON'T HUNT YOU UNLESS YOU HUNT THEM. DON'T BELIEVE ME? CHECK OUT THIS VIDEO!

A music clip plays in which Laura wears a full shark costume.

MUSIC plays.

As shark Laura swims, dances, reads inside a library and performs other activities, she sings
SOME ARE REALLY TINY, SOME ARE BIG. THEY SWIM IN THE SEA.
THEY'RE SHARKS. THEY'RE IN THE DEEP, DEEP SEA.

The clip ends.

Back inside the underwater tree fort, Lucas wears goggles and speaks in a whale language.

Still swimming in the water, Greg says LUCAS? IS THERE A WHALE?

Lucas says I DON'T KNOW.

Greg says LUCAS?

[FROGHORN]

Lucas says YYOOOUUUUU TYYYAAAAOOONNN SSSWWOOOMMMMNN WWWIII MMMUUIII.

Greg says UMMM. I DON'T THINK THAT'S WHALE LANGUAGE?

Lucas says YES, IT IS. I LEARNT IT IN OUR "TRY SOMETHING NEW." EPISODE ON MONDAY!

Greg says IS THAT WHALE LANGUAGE?

Greg swims up to the tree fort, steps inside and says OH! LUCAS?

Lucas says YOU MADE IT.

Greg says I'VE BEEN SO WORRIED ABOUT YOU. WHERE HAVE YOU BEEN?

Lucas says THE QUESTION IS WHERE HAVE YOU BEEN?

Greg says YEAH. I WAS LOOKING FOR YOU AND I TALKED TO THIS TURTLE AND HE TOLD ME MORE THINGS ABOUT TURTLE S THAN I WANTED TO KNOW, LIKE THE COME PASS IN THEIR HEAD S AND DIFFERENT SPECIES. SO I KNOW WAY MORE ABOUT TURTLES THAN I EVER WANTED TO KNOW. AND THEN I ALSO LEARNED ABOUT SHARKS, DIFFERENT SPECIES OF SHARKS., SO MANY... SO MANY.

[LAUGHTER]

Lucas says YEAH. IT'S FUN TO BE HERE HANGING OUT.

Greg says YEAH, IT'S NICE HERE.

Lucas says YEAH. I KNOW. WE JUST HUNG OUT. YEAH. WE PLAYED SOME LIKE WHAT IS IT.

Greg says DID YOU KNOW THAT WHALES AREN'T ACTUALLY A FISH, LUCAS? YOU KNOW THE GREAT WHITE SHARK IS THE BIGGEST FISH IN THE OCEAN. THAT'S TRUE. SOME MIGHT THINK, NO, THE WHALE IS THE BIGGEST FISH IN THE OCEAN BUT THAT'S NOT TRUE AT ALL, BECAUSE WHALES ARE MAMMALS. SO THAT INCLUDES THINGS LIKE WHALES AND DOLPHINS.

Lucas says I LOVE DOLPHINS. I WOULD LOVE TO SEE DOLPHIN. ALSO WHALES ARE REALLY EMOTIONAL LY INTELLIGENT, WHICH IS MY FAVORITE THING ABOUT THEM. OKAY, WE GOT TO GO BACK TO THE TREE FORT. IT'S TIME.

Greg says RIGHT. HERE WE GO. READY? ONE, 2, 3...

He pulls the lever and the tree fort spins quickly.

Greg says DOWN THIS SIDE. TRY TO HOLD ON TO SOMETHING.

[LAUGHTER]

The fort lands in the snowy forest again.

Lucas says OKAY. WE MADE IT BACK.

Greg says WHAT A FUN ADVENTURE, YEAH.

Lucas says WE GOT TO KEEP THIS THING AROUND FOR SURE.

Greg says TVOKIDS WE WANT YOU TO JOIN US ON OUR ADVENTURES. SO MAKE SURE YOU ALWAYS CALL IN, OKAY? YOU KNOW THE NUMBER.

A caption reads "Call us at 1-888-886-5437."

Lucas says YEAH, WE WANT TO TALK TO YOU FOR SURE. WE WANT TO TALK TO YOU ABOUT YOUR PETS. MAYBE YOU HAVE SOME COOL OUTFITS FOR WINTER.

Greg says AND ALSO TVOKIDS WE WANT TO CHECK OUT MORE THINGS TVOKIDS RELATED. YOU CAN ALWAYS GO TO THE WEBSITE TVOKIDS.COM. WE HAVE EPISODES, GAMES. SO YEAH.

Lucas says YEAH, A LOT TO DO. YOU DEFINITELY SHOULD DO THAT. WE'RE OUT OF TIME.

Greg says YES.

Lucas says WE SHOULD SING A SONG. WE HAVEN'T SUNG A SONG IN SO LONG...

Greg says YEAH. HERE WE GO.

As Greg plays the ukulele, they both sing
SO LONG SEE YA LATER I BET TOMORROW WILL EVEN BE GREATER BUT NOW IT'S TIME TO SAY GOOD BYE TO YOU... SO LONG SAYONARA CLUE GO TO TVOKIDS.COM TO FIND OUT. SIGH UNDERWATER.

Greg says I'M GREG. EAT YOUR VEGETABLES.

Music plays as a slate shows the end credits.
