THAT'S BETTER.

THANKS, MOM.

>> DAD SAYS TO TELL YOU THAT HE AND SHINY AND DON FLEW OVER TO THE BIG POND TO PLAY KEEPAWAY.

HEY, BUDDY!

DID YOU THINK OF A WAY TO COOL DOWN YET?

>> FANNING SEEMS TO HELP, BUT I HAVE TO STAY IN THE SHADE.

>> WELL, I'LL STAY HERE AND KEEP YOU COMPANY THEN.

WANT TO PLAY A GAME?

>> [SIGHS] IT'S TOO HOT TO PLAY.

>> COME ON.

LET'S THINK OF SOMETHING.

>> IT'S TOO HOT TO THINK.

>> UHH!

>> OH, OK. HEY, MOM, ARE THERE ANY DINOSAURS WHO KNOW HOW TO COOL OFF WHEN IT'S HOT BESIDES FLYING?

>> HMM.

YOU KNOW, DIFFERENT SPECIES OF DINOSAURS HAVE DIFFERENT WAYS OF COOLING OFF WHEN IT'S HOT.

>> LIKE RIGHT NOW, WE'RE SITTING IN THE SHADE.

>> BUT I KNOW A SPECIES CALLED STEGOSAURUS THAT HAS A GREAT WAY TO COOL OFF.

IT USES THE PLATES ON ITS BACK.

>> PLATES?

>> COOL!

>> AND THEY LIVE IN THE JURASSIC PERIOD, WHERE IT'S EVEN HOTTER.

>> COULD WE GO AND VISIT THEM?

>> SURE!

WE COULD TAKE THE DINOSAUR TRAIN AND VISIT THEM.

YOU COULD ASK THEM HOW THEY MANAGE TO KEEP THEIR COOL WHEN IT'S HOT.

>> OH, BOY!

WE GET TO RIDE THE DINOSAUR TRAIN.

>> [SQUAWKS] YEAH!

[WHISTLE BLOWS] OH, FEEL THAT BREEZE.

>> I KNOW.

IT'S COOLER ALREADY.

>> TICKETS.

TICKETS, PLEASE.

THANK YOU.

THANK YOU VERY MUCH.

WELL, MRS. PTERANODON AND TINY AND BUDDY.

HELLO.

>> HELLO, MR.

CONDUCTOR.

>> AH, I SEE YOU'RE TRAVELING WAY BACK TO THE JURASSIC PERIOD TODAY.

>> YEAH.

WE'RE GOING TO VISIT THE STEGOSAURUS AND SEE HOW THEY BEAT THE HEAT.

>> WITH THEIR PLATES.

>> THAT'S RIGHT, TINY.

STEGOSAURUS HAVE PLATES ON THEIR BACKS.

>> ARE STEGOSAURUS PLATES LIKE THE PLATES IN THE DINING CAR?

>> YOU MEAN THESE?

WELL, EVEN THOUGH STEGOSAURUS PLATES AND OUR DINING CAR PLATES ARE THE SAME WORD, IT MEANS SOMETHING DIFFERENT.

STEGOSAURUS PLATES HAVE THAT NAME BECAUSE THEY'RE FLAT LIKE A PLATE.

>> WOW.

YOU KNOW A LOT OF STUFF.

>> WELL, TROODONS ARE THE SMARTEST DINOSAURS.

>> I CAN'T WAIT TO SEE THE STEGOSAURUS PLATES.

>> YEP.

YOU'LL SEE FOR YOURSELVES WHEN YOU GET TO THE JURASSIC PERIOD.

OH, SPEAKING OF WHICH, TIME TUNNEL, FOLKS!

TIME TUNNEL APPROACHING!

[BELL RINGING] >> TIME TUNNEL!

♪ LA LA LA LA LA ♪ TIME TUNNEL!

I LOVE THE TIME TUNNEL.

♪ LA LA LA LA LA ♪ >> I LIKE IT, TOO, TINY.

NOW ENTERING THE JURASSIC PERIOD.

NEXT STOP, STEGOSAURUS FOREST.

THAT MEANS YOU, FOLKS.

BYE-BYE!

>> GOOD-BYE!

>> SEE YOU!

>> TRY TO STAY COOL!

AND HAVE FUN LEARNING ABOUT PLATES!

>> WOW.

YOU WERE RIGHT, MOM.

IT'S EVEN HOTTER HERE IN THE JURASSIC THAN IT WAS BACK HOME IN THE CRETACEOUS.

>> YUP.

COME ON!

LET'S GO FIND SOME STEGOSAURUS AND A LITTLE SHADE.

[SIGHS] SEE, KIDS?

IN THE JURASSIC PERIOD, THERE'S NO GRASS OR FLOWERS.

>> NO FLOWERS?

WHY?

>> OH, I DON'T KNOW WHY, TINY.

HERE IN THE JURASSIC PERIOD, THE EARTH IS DIFFERENT.

NO FLOWERS, LOTS OF LOW-LYING HERBS AND FERNS, AND THAT'S WHAT STEGOSAURUS LIKE TO EAT, SO WE SHOULD FIND SOME AROUND HERE.

>> THERE THEY ARE, I THINK.

>> OH!

BOY, YOUR EYES ARE SHARP, BUDDY!

IT'S A HERD OF STEGOSAURUS.

CAN YOU SEE THEIR PLATES?

>> YEAH.

I GOT TO FIND OUT HOW THEY USE THEM TO BEAT THE HEAT.

>> LET'S GO TALK TO THEM.

[SQUAWKS] >> LOOK, KIDS.

DID YOU NOTICE HOW THE STEGOSAURUS ARE ALL STANDING FACING ONE WAY?

>> HMM.

IS THAT HOW THEY'RE BEATING THE HEAT?

I WONDER.

>> LET'S ASK THEM IF THEY'RE DOING THAT TO COOL OFF.

COME ON, BUDDY.

>> UM...YOU GO ASK.

I'LL WAIT HERE.

THEY'RE REALLY BIG UP CLOSE.

>> HA HA!

COME ON.

[GRUNTING] >> OH, HEY, MAN.

HOW YA DOIN'?

>> UM...FINE.

>> HI!

I'M TINY PTERANODON, AND THIS IS MY BROTHER BUDDY.

>> HI.

HI.

>> WELL, HI, BUDDY AND TINY.

I'M MORRIS.

MORRIS STEGOSAURUS.

IT'S AWESOME TO MEET YOU.

>> I REALLY LIKE YOUR PLATES.

>> YEAH, THEY'RE BEAUTIFUL.

>> OH.

MY PLATES?

HEH!

THANKS.

YEAH, I DIG 'EM.

>> 1, 2, 3, 4, 5, 6, 7... 14, 15, 16, 17.

17 PLATES.

>> VERY GOOD, SMALL GUY.

I DO HAVE 17 PLATES BACK THERE.

>> [SQUAWKS] THAT WAS FUN.

>> I'M ALWAYS FORGETTING I HAVE THAT TAIL SWINGING AROUND BEHIND ME.

WHOOPS.

SORRY.

THERE GOES MY TAIL.

[WIND WHOOSHING] >> TINY, I HAVE A HYPOTHESIS.

>> YOU MEAN AN IDEA YOU CAN TEST?

>> YEP.

MY HYPOTHESIS IS, MAYBE THE WIND BLOWS THROUGH THEIR PLATES, AND THAT'S WHAT COOLS THEM DOWN.

>> SORRY.

I FORGOT.

WHAT WERE YOU SAYING ABOUT MY PLATES?

>> WELL, WE WERE WONDERING, DO YOU STAND WITH YOUR PLATES FACING THE WIND TO HELP YOU COOL OFF?

>> WELL, SURE, DUDE.

DOESN'T EVERYBODY?

WHAT ARE THE OTHER STEGOSAURUS DOING?

>> [SQUAWKS] >> OOPS.

MY CRAZY TAIL AGAIN.

SORRY.

[ALL LAUGHING] YEAH, SEE, ALL THE STEGOSAURUS ARE KIND OF LINED UP, SO THE WIND CAN BLOW DOWN RIGHT THROUGH OUR PLATES, WHICH ARE, YOU KNOW, CONNECTED TO US, SO IT HELPS COOL US OFF.

YOU GET IT?

>> MAYBE WE COULD TRY IT.

WE NEED PLATES, THOUGH.

>> WELL, THAT'S COOL WITH ME.

GO FOR IT.

I'LL BE RIGHT HERE, DOIN' MY THING--EATIN' FERNS.

>> [GIGGLES] >> HOW DOES THAT FEEL?

ANY COOLER?

>> NO.

I ACTUALLY FEEL A LITTLE HOTTER.

I DON'T THINK OUR PLATES WORK LIKE THEIRS, BUDDY.

>> NO.

THEY'RE AREN'T CONNECTED TO US LIKE MORRIS' PLATES ARE CONNECTED TO HIM.

>> YEAH.

FOR OUR SPECIES, STANDING IN THE SHADE WORKS BETTER, AND MAYBE THESE WOULD MAKE GOOD FANS.

HA HA!

MORRIS?

ARE YOUR PLATES ALSO LIKE ARMOR, TO PROTECT YOU FROM BIG MEAT EATERS?

>> TAIL!

INCOMING!

>> OH, SORRY.

WELL, THE PLATES DO MAKE US LOOK BIGGER, AND THAT HELPS SCARE OFF THE MEAT EATERS...SOMETIMES.

BUT, YOU KNOW, THE MAIN THING I LIKE ABOUT OUR PLATES IS, LIKE YOU SAID, TINY, THEY'RE BEAUTIFUL, MAN.

>> YEAH.

>> THEY ARE.

>> AND WHEN I LOOK AROUND, EVEN FROM A LONG WAY OFF, I CAN RECOGNIZE MY FRIENDS, THE OTHER STEGOSAURUS.

RIGHT, DUDES?

>> RIGHT.

>> OOPS!

THERE GO MY FRIENDS.

WE JUST KIND OF BROWSE ALONG THE FOREST FLOOR, LOOKING FOR TASTY FERNS.

I BETTER CATCH UP.

SEE YA.

>> GOOD-BYE, MORRIS!

>> THANKS FOR TALKING TO US ABOUT YOUR COOL PLATES.

>> YOU ARE TOTALLY WELCOME.

I'M GLAD YOU LIKE 'EM.

BYE!

[DINOSAURS ROARING] >> LOOK, MOM.

NOW THE WIND IS BLOWING THIS WAY, AND ALL THE STEGOSAURUS ARE STANDING WITH THEIR PLATES FACING IT.

>> I THINK YOUR HYPOTHESIS WAS RIGHT, BUDDY.

THEY DO SEEM TO USE THEIR PLATES TO COOL OFF.

AH!

WELL, IT'S GETTING LATE, KIDS.

IT SHOULD BE COOLER NOW AT THE NEST.

>> [SQUAWKS] >> LET'S GET BACK TO THE DINOSAUR TRAIN.

>> YEAH!

BACK ON THE DINOSAUR TRAIN!

[WHISTLE BLOWS] >> THAT WAS FUN.

THANKS FOR TAKING US TO THE JURASSIC PERIOD, MOM.

>> YEAH!

IT WAS SO HOT, IT WILL MAKE THE CRETACEOUS PERIOD SEEM EVEN COOLER WHEN WE GET BACK.

>> TICKETS, PLEASE.

TICKETS.

HELLO, BUDDY AND TINY.

WELL, DID YOU FIND OUT ABOUT STEGOSAURUS PLATES?

>> YEAH.

WE THINK THEY'RE FOR A LOT OF THINGS.

THEY HELP KEEP STEGOSAURUS COOL, THEY MAKE THEM LOOK BIGGER TO SCARE AWAY THE MEAT EATERS.

>> AND MAYBE THEY EVEN HELP THE STEGOSAURUS TELL WHO ELSE IS STEGOSAURUS, AND THEY'RE REALLY BEAUTIFUL.

>> I'M GLAD TO BE GOING BACK TO THE CRETACEOUS, THOUGH.

>> YEAH!

WE HAVE FLOWERS!

>> AND DON'T FORGET--FISH FOR DINNER!

>> HOORAY!

MY FAVORITE!

♪ IF I COULD WISH FOR JUST ONE DISH MY GREATEST WISH WOULD BE MORE... ♪ >> LET ME GUESS.

FISH?

>> YEAH!

FISH!

HA HA HA!

>> HA HA HA HA!

>> OOPS.

HA HA!

BETTER GET BACK TO WORK.

TIME TUNNEL!

TIME TUNNEL APPROACHING, FOLKS!

[WHISTLE BLOWS] [PTERANODON SQUAWKING] >> AND THEN BUDDY CAME UP WITH A GREAT HYPOTHESIS.

TELL THEM, BUDDY.

>> [GULPS] THE STEGOSAURUS STOOD WITH THEIR PLATES FACING THE WIND, SO IT CAN COOL THEM DOWN.

THAT'S HOW I THINK STEGOSAURUS USE THEIR PLATES TO BEAT THE HEAT.

>> OH, YOU TELL THEM, BUDDY.

[SQUAWKS] >> HEY.

[WIND WHOOSHING] I FEEL A BREEZE.

IT'S FINALLY COOL!

[ALL CLAMORING] >> AND TOMORROW, IF IT'S HOT AGAIN, I HAVE A NEW HYPOTHESIS TO TEST OUT.

I BET WE CAN ALL GET COOLER BY JUMPING IN THE BIG POND.

>> YEAH!

BIG POND!

>> WOO HOO!

>> AWESOME!

>> HI.

I'M DR. SCOTT, THE PALEONTOLOGIST, AND THIS IS A STEGOSAURUS.

>> STEGOSAURUS.

>> STEGOSAURUS.

>> STEGOSAURUS.

>> STEGOSAURUS LIKE MORRIS HAD PLATES ON THEIR BACK, BUT WE DON'T KNOW EXACTLY WHAT THEY USED THEM FOR.

ONE IDEA, OR HYPOTHESIS, IS THAT STEGOSAURUS USED THEIR PLATES TO MAKE THEMSELVES LOOK EVEN BIGGER, MAYBE TO SCARE AWAY MEAT EATERS OR TO SHOW OFF TO OTHER DINOSAURS.

ANOTHER HYPOTHESIS IS THAT THEY USED THEIR PLATES TO COOL THEMSELVES OFF.

SINCE WE CAN'T WATCH STEGOSAURUS IN ACTION, PALEONTOLOGISTS LIKE TO LOOK AT ANIMALS TODAY TO SEE WHAT WE CAN LEARN FOR THEM.

AND THERE IS ONE ANIMAL WE ALL KNOW THAT IS A BIG PLANT EATER WITH A LONG TRUNK AND BIG EARS THAT IT USES FOR COOLING OFF AND SHOWING OFF.

>> ELEPHANT.

>> BIG ELEPHANTS USE THEIR EARS TO MAKE THEMSELVES LOOK BIGGER SO THEY CAN SCARE OFF OTHER ELEPHANTS OR EVEN MEAT EATERS LIKE LIONS.

AND ELEPHANTS ALSO USE THEIR EARS TO COOL THEMSELVES OFF.

THEY PUSH WARM BLOOD FROM INSIDE THEIR BODIES OUT INTO THEIR EARS AND THEN FLAP THEIR EARS BACK AND FORTH LIKE HUGE FANS.

THIS COOLS THE BLOOD, WHICH THEN GOES BACK INTO THE BODY, KEEPING THE WHOLE ANIMAL COOLER.

LET'S HEAR IT FOR THE STEGOSAURUS.

>> YAY, STEGOSAURUS!

>> KEEP WATCHING FOR MORE DINOSAUR DISCOVERIES.

>> BUDDY CONDUCTOR.

TODAY WE'RE GOING TO VISIT THE BIG POND AND DISCOVER THE DIFFERENT FLOWERS THAT GROW IN THE CRETACEOUS TIME PERIOD.

SO, COME ON ALONG WITH ME ON THE DINOSAUR TRAIN.

ALL ABOARD!

>> LET'S PLAY FOLLOW THE LEADER.

I'LL BE THE LEADER.

SO, FOLLOW ME.

[HUMMING] >> I DON'T REALLY WANNA FOLLOW SHINY.

I WANT TO BE THE LEADER.

HEY, THIS IS FUN!

I LOVE HOPPING.

>> DON, WE'RE DONE HOPPING.

WE'RE TWIRLING NOW.

[LAUGHTER] >> HEY, WATCH OUT.

MOM'S FLOWERS.

>> WHOA.

HEY, THAT REMINDS ME.

YOU WANTED TO LOOK FOR FLOWERS FOR MOM TODAY, RIGHT, TINY?

>> RIGHT, BECAUSE TODAY IS MOM'S SPECIAL DAY.

WE'RE GIVING MOM THE DAY OFF.

I THOUGHT WE COULD CALL IT MOTHER'S DAY.

>> OOH, MOTHER'S DAY.

>> I LIKE THAT NAME.

>> YUP.

IT'S A DAY JUST FOR MOM.

SHE DOESN'T HAVE TO DO ANYTHING AT ALL.

SHE CAN RELAX.

>> I KNOW--LET'S GET MOM A SPECIAL PRESENT.

>> HO, A SPECIAL PRESENT FOR MOM?

GOOD IDEA, TEAM.

WHAT KIND OF PRESENT?

>> YOU KNOW, MOM TOLD ME THAT SHE LIKES BIG, RED FLOWERS.

>> HEY, THEN LET'S FIND MOM SOME BIG, RED FLOWERS FOR HER PRESENT.

>> I'M GONNA FIND SHINY SHELLS AND MAKE HER A CROWN, AND ONE FOR ME.

>> YOU KNOW WHAT I'M GONNA GIVE HER?

A GREAT, BIG FISH.

>> HEY, I KNOW A PLACE THAT HAS FLOWERS AND SHINY SHELLS AND FISH.

THE BIG POND.

ALL OF US COULD GO THERE AND FIND HER A PRESENT.

>> [SQUAWK] YOU'RE RIGHT, BUDDY.

THERE'S LOTS OF FLOWERS AT THE BIG POND.

>> THE THING ABOUT FLOWERS AND ME IS THEY ALWAYS... [SNIFFS] UH, MAKE ME... AH-AH-AH-CHOO!

SNEEZE.

I'M NOT SURE WHY.

>> [LAUGHS] THOSE ARE GREAT IDEAS, KIDS.

ALL RIGHT, THEN, TEAM PTERANODON.

LET'S TAKE THE DINOSAUR TRAIN TO THE BIG POND.

READY TO GO?

[CHEERING] >> GO?

WHERE ARE YOU GOING?

>> [GASP] >> WE'RE GOING ON AN ADVENTURE.

>> YEAH, WITH DAD.

AND YOU GET THE DAY OFF, MOM.

IT'S MOTHER'S DAY.

>> [SQUAWK] MOTHER'S DAY?

>> YEAH.

YOU STAY HOME AND RELAX.

>> OH, STAY HOME AND RELAX?

THAT SOUNDS LOVELY.

OK.

I'M GOING TO TAKE A LONG BATH IN THE SEA, LIE ON THE WARM ROCKS, AND MAYBE TAKE A NAP.

OK, HAVE FUN, KIDS.

BYE!

>> BYE, MOM!

>> AH-AH-CHOO!

[LAUGHTER] >> WHAT?

[TRAIN'S WHISTLE BLOWS] >> TICKETS.

TICKETS, PLEASE.

AH, GOING TO THE BIG POND, I SEE.

>> YEAH!

I'M GONNA FIND A HUGE FISH.

>> I'M GONNA FIND SHINY SHELLS.

>> I'M GONNA FIND FLOWERS.

>> AND I'M GONNA HELP YOU FIND THEM, TINY.

WE'LL DO IT TOGETHER, AS A TEAM.

HIGH 2!

>> YEAH!

>> WELL, YOU'RE IN LUCK.

THERE ARE FISH AND SHELLS AT THE POND, AND YES, FLOWERS, TOO.

>> I HOPE THERE ARE RED FLOWERS.

>> OH, YOU BET THERE ARE RED FLOWERS.

BUT YOU KNOW WHAT?

THERE WEREN'T ALWAYS FLOWERS EVERYWHERE.

HERE'S WHAT IT LOOKED LIKE IN THE TRIASSIC TIME PERIOD.

NO FLOWERS.

>> [GASP] NO FLOWERS?

>> BUT THEN, DURING THE JURASSIC PERIOD, MORE PLANTS AND LITTLE FLOWERS APPEARED.

>> I SEE SOME LITTLE FLOWERS!

HOORAY!

>> AND NOW WE'RE IN THE CRETACEOUS TIME PERIOD, AND LOOK!

ALL KINDS OF BIG, FANTASTIC FLOWERS ARE GROWING.

>> I CAN'T WAIT!

BRING ON THE FLOWERS.

>> AND REMEMBER, WHEN YOU FIND THOSE FLOWERS, YOU'LL ALSO SEE BEES BUZZING AROUND THEM, TOO.

SO, "BEE" ON THE LOOKOUT FOR BEES!

[TRAIN'S WHISTLE BLOWS] NEXT STOP--BIG POND.

[BRAKES SCREECH] [LAUGHTER] >> WELL, KIDS, HAPPY FISHING, SHELL COLLECTING, AND FLOWER FINDING!

[CHEERING] >> RED FLOWERS, RED FLOWERS, RED FLOWERS.

>> HEY, LOOK, BUDDY.

TEENY YELLOW FLOWERS, LIKE MOM HAS AT HOME.

>> [SNIFFS] YUP, AND THEY SMELL LIKE MOM'S, TOO.

>> [SNIFFS] AH-AH-CHOO!

THOSE FLOWERS ARE MAKING ME AH-AH-CHOO.

WHAT CAN I DO?

I KNOW--FISH FOR FISHY FISHIES.

♪ LA-LA-LOO ♪ >> HA HA.

I'LL HELP YOU, DON.

I CAN BE YOUR SPOTTER.

BUT FIRST, TEAM PTERANODON, I WANT EACH OF YOU TO GO TO WHERE YOU'LL BE LOOKING FOR MOM'S PRESENT AND GIVE ME A SHOUT, OK?

I WANT TO BE ABLE TO HEAR YOU.

[LAUGHTER] >> ♪ I'M HERE ♪ [SQUAWK] >> I'M HERE.

[SQUAWK] >> WE'RE HERE.

[RAWR] >> [SQUAWK] >> GOOD, AND I'M HERE.

[SQUAWK] >> [HUMMING] >> [SNIFFS] TINY, LOOK.

IT'S A BEE.

>> REMEMBER WHAT THE CONDUCTOR SAID?

IF THERE ARE BEES, THERE MUST BE FLOWERS.

>> GOOD.

THEN FOLLOW ME, AND THE BEE.

>> OK. ONE PILE FOR SHINY SHELLS, ONE PILE FOR SHINIER SHELLS, AND ONE FOR SUPER SHINY SHELLS.

OOH, YOU ARE A SUPER, SUPER SHINY SHELL.

MM, YEAH, I NEED TO START A NEW PILE.

>> HMM.

THESE FLOWERS ARE DIFFERENT THAN THE OTHERS WE'VE SEEN.

THESE HAVE A LONG STEM AND A SMALLER BLOSSOM.

>> I SEE OUR BEE LIKES THEM.

>> YEAH.

LOOKS LIKE HE'S SMELLING IT.

>> NOW HE'S FLYING AWAY.

LET'S GO!

>> THESE FLOWERS ARE COMPLETELY DIFFERENT, TOO.

>> BUT STILL NO BIG, RED ONES.

>> LOOK, TINY--THESE HAVE 1, 2, 3, 4, 5, 6 PETALS IN A CIRCLE.

>> AND LITTLE, PINK LINES IN THE MIDDLE.

OUR BEE IS SMELLING THESE, TOO.

WHAT'S THAT STUFF IN THE MIDDLE OF THE FLOWER?

IT'S KINDA POWDERY.

>> I'M NOT SURE, BUT IT LOOKS LIKE THE BEE IS TAKING IT FROM THE FLOWER.

MAYBE IT'S THE PART HE LIKES BEST.

>> YEAH.

MAY"BEE."

[LAUGHTER] >> HEY, IT'S FLYING AGAIN.

COME ON, BEE.

HELP US FIND SOME BIG, RED FLOWERS.

>> HA HA.

[SPLASH] >> DAD, LOOK--A BIG SPLASH.

>> [SQUAWK] THAT MEANS A BIG FISH!

LET'S BOTH DIVE FOR IT.

>> GERONIMO!

>> OK. THAT WAS A BIG SPLASH FOR A VERY SMALL FISH.

>> GUESS WE HAVE TO KEEP FISHING, BUT YOU KNOW WHAT I LOVE?

>> FISHING!

[LAUGHTER] >> NICE, BUT COULD BE SHINIER.

TOO SMALL.

TOO BIG.

HMM.

IS THIS EVEN A SHELL?

AAH!

IT HAS LEGS!

>> I HAVE A HYPOTHESIS ABOUT OUR BEE.

IT LIKES TO GO TO EVERY KIND OF FLOWER IT CAN FIND.

IT'S EASY TO TEST.

LOOK.

>> YUP, NOW IT'S VISITING ALL THESE YELLOW FLOWERS.

RED ONES, BEE.

FIND US SOME BIG, RED ONES.

[BEE BUZZING] >> YEAH!

>> HUH.

NOT EXACTLY BIG ENOUGH FOR A SPECIAL MOTHER'S DAY PRESENT.

>> [SQUAWK] >> [GASP] GREAT HORNY TOADS!

WHAT A FISH!

[CHOMP] >> YAY!

GO TEAM PTERANODON!

WOO-HOO-HOO!

>> SHINY.

NOT VERY SHINY.

SMALL.

MEDIUM.

ICKY.

OOH, VERY SHINY.

UHH.

I WONDER IF I HAVE ENOUGH.

>> [SQUAWKING] OK, TEAM.

GATHER 'ROUND.

LET'S HUDDLE BY THE PUDDLE.

>> WHAT?

ALREADY?

>> [SQUAWK] >> THAT'S DAD.

WE BETTER HEAD BACK.

>> OH, IT'S TIME TO GO.

WE LOOKED AND LOOKED AND WE SAW YELLOW, PINK, AND WHITE FLOWERS BUT NO BIG, RED ONES.

[BEE BUZZING] >> WHOA.

WHERE IS THE BEE GOING?

>> BUDDY, LOOK WHAT OUR BEE FOUND.

BIG, RED FLOWERS.

>> YAY!

>> AWESOME!

>> SWEET!

[BEE BUZZING] >> WOW.

THEY'RE SO PERFECT FOR MOM.

>> SHE'LL LOVE THEM.

LET'S PICK SOME AND BRING THEM HOME.

>> WAIT!

DON'T PICK THEM.

MOM SAID THAT ALL FLOWERS ARE ALIVE AND SHOULD BE LEFT ALONE TO JUST LOOK AT AND SMELL.

>> TINY, WHAT IF WE TAKE THIS WHOLE LOG BACK TO MOM?

>> [GASP] BUDDY, THAT'S A GREAT IDEA.

COME ON, LET'S GO.

>> WELL, I'LL BE.

YOU KIDS FOUND YOUR BIG, RED FLOWERS.

>> YUP.

A BEE TOOK US RIGHT TO THEM.

WELL, AFTER FIRST VISITING EVERY FLOWER IN THE BIG POND.

>> YEAH.

HE SEEMS TO LIKE ALL DIFFERENT COLORED FLOWERS.

>> RIGHT, TINY.

BEES SEEM TO LIKE BRIGHTLY COLORED FLOWERS THE BEST.

>> IT LOOKS LIKE THE BEE IS DRINKING SOMETHING FROM THE FLOWER.

>> YUP.

THE BEE TAKES A DRINK FROM EVERY FLOWER.

IT'S SOMETHING CALLED NECTAR.

AND WHILE HE'S GETTING NECTAR, SOMETHING ELSE STICKS TO HIS LEGS.

IT'S CALLED POLLEN, AND THE BEE SPREADS IT FROM FLOWER TO FLOWER.

>> DOES THE POLLEN HELP MAKE MORE FLOWERS?

>> EXACTLY.

WAY TO USE THE OLD DINO BRAIN, BUDDY.

>> HA HA.

>> COME ON, HON.

ALMOST THERE.

>> 1, 2, 3, OPEN YOUR EYES.

>> [SQUAWK] OH, MY GOODNESS.

PRESENTS?

>> A CROWN OF THE SHINIEST SHELLS.

>> A GIANT FISH FOR MY MOM.

>> BIG, RED FLOWERS FOR YOUR GARDEN!

>> OH, GROWING OUT OF THEIR OWN LOG.

THEY'RE BEAUTIFUL.

ALL THESE PRESENTS ARE JUST WONDERFUL, KIDS.

>> HAPPY MOTHER'S DAY!

>> HAPPY MOTHER'S DAY, HON.

>> OH, I MUST BE THE LUCKIEST PTERANODON IN THE MESOZOIC ERA.

THANK YOU, KIDS.

[SNIFFS] >> [SNIFFS] WHOOPS.

I FORGOT AGAIN.

AH-CHOO!

[LAUGHTER] >> WHAT?

>> [BUZZING] >> HI.

I'M DR. SCOTT, THE PALEONTOLOGIST.

WHAT'S THAT BUZZING SOUND?

>> [BUZZING] >> DID YOU KNOW THAT BEES HAVE BEEN AROUND SINCE THE MESOZOIC ERA WHEN DINOSAURS LIVED, AND THEY'VE ALWAYS DONE THE SAME THINGS--THEY'VE BUZZED AND THEY HELPED PLANTS MAKE MORE PLANTS.

WHEN BEES LAND ON FLOWERS LOOKING FOR SWEET-TASTING NECTAR, SOMETHING CALLED POLLEN INSIDE THE FLOWER GETS TRAPPED ON THEIR LEGS.

THE BEES CARRY THIS POLLEN TO OTHER FLOWERS, WHICH HELPS THE PLANTS MAKE MORE PLANTS.

SO FLOWERS HELP BEES AND BEES HELP FLOWERS.

THE FIRST BEES AND FLOWERS LIVED WITH DINOSAURS, AND WE'RE SURE GLAD THAT BEES ARE STILL AROUND TODAY DOING THEIR JOB HELPING PLANTS.

>> [BUZZING] >> SO, REMEMBER, GET OUTSIDE, MAKE YOUR OWN DISCOVERIES, AND "BEE" A BACKYARD SCIENTIST.
