Hey Grown Ups, this episode of Wow in the

0:02

World is brought to you by Huggy's Little Movers.

0:05

Huggy's knows that babies come in

0:07

all shapes and sizes, and parents

0:09

know that there's nothing worse than

0:11

an ill-fitting diaper, especially on an

0:13

active baby. Phew!

0:15

Huggy's Little Movers offer 12-hour protection against

0:17

leaks, and are curved to fit all

0:20

curves. So your babies will feel comfy

0:22

no matter how much they move around.

0:24

And they do tend to move around. A lot.

0:27

Get your baby's butt into the best-fitting

0:29

diaper. Huggy's Little Movers. We got you,

0:31

baby. Hey,

0:36

Wowser fans, the summer of wow is

0:38

here. And all summer long,

0:40

we'll be sharing weekly Find Your

0:43

Wow missions for you to

0:45

do at home. And this week's

0:47

mission is all about bugs. We

0:49

challenge you to create your own

0:52

bug habitat. Raid the recycling bin

0:54

for a jar or a box, and

0:56

fill it with sticks, soil, leaves,

0:59

rocks, and anything else you think

1:01

would make a wild bug feel at home.

1:03

And don't forget to add a welcome mat

1:05

at the entrance so that all the bugs

1:08

know that they're invited. And once

1:10

you complete this mission, there's more! Visit

1:13

wondering.com/summer of wow for more

1:15

missions and wow in the

1:17

world episodes. And to

1:19

send us photos and videos

1:21

from your missions, visit wondering.com/summer

1:24

of wow. The summer

1:26

of wow is now. Four

1:28

feet at three, two, one, mission. The

1:31

final part of

1:34

mission of that magnificent

1:36

proportion. I don't know

1:38

what you've been told,

1:41

but we're in a golden age.

1:45

We're in a golden age. Oh,

2:02

I'm so glad I have this laboratory of bad

2:04

ideas to test out all of these bad ideas

2:06

we have, Reg. Oh, hey, can you

2:08

hear me? That left-handed monkey wrench over there?

2:12

Thanks, buddy. Okay, just a couple

2:14

of more twists this way. And...

2:17

Ah! That should do it. That's

2:20

fine. I didn't need

2:22

that part anyway. Mandy,

2:25

are you in

2:27

there? My

2:29

baby parrots just sprouted in there

2:31

so cute. You've got to see

2:33

them. Hello?

2:36

Coming! Quick,

2:38

Reg, throw a sheet over this thing. We can't

2:40

let Guy-Ras see it yet, okay? Mandy! Almost

2:43

there! Walk, walk,

2:45

walk, walk, walk, walk, walk, walk. Opening

2:49

the door? Guy-Ras-y!

2:53

What took you so long, Mandy? And why

2:55

are you so sweaty? Oh, the sweat? Yeah.

2:59

I was just thinking about a really hard math

3:01

problem. Huh. So what's

3:03

up? Well, you know those baby carrots I planted

3:05

last year? Oh, yeah. How can I forget? Well,

3:08

they finally sprouted. Look

3:11

at these things. Ooh! They're

3:13

so cute! I

3:15

just squeezed them. Hey, Reg, come here.

3:18

Look at these little baby carrots. Oh!

3:22

No! Reg, the sheet

3:24

concealing the super secret robot project that

3:26

I don't want Guy-Ras to see is still attached to

3:28

your... feet. What

3:32

in the... Okay,

3:35

Carras, before you say anything, it's

3:37

not what it looks like. Really? Because it

3:40

looks like you've created some sort of ten-foot-tall

3:42

robotic dinosaur in your laboratory of

3:45

bad ideas. Okay, then

3:47

it's exactly what it looks like. What

3:49

even is this thing? Okay, Carras, what

3:51

you're looking at here could

3:54

be the latest and greatest

3:56

in pranking robotics.

3:59

Pranking? robotics? Uh-huh. It's a new

4:01

field of robotics that I invented.

4:04

Here, you want to see this thing in action? Uh,

4:07

I'm not sure, Mindy. Is

4:09

it safe? Yes, of course

4:11

it's not safe, Gyroz. Here,

4:13

let me just get out

4:15

the remote control here. And

4:18

extending the antenna slide. What?

4:23

I added that sound effect. And now

4:25

we just have to push on the

4:27

button in three, two,

4:30

one. Uh,

4:42

Mindy, is it supposed to

4:44

be moving towards us? Uh,

4:46

no, not exactly. Let me

4:48

just get this thing under

4:50

control here real quick. Uh,

4:52

maybe it's this button? Okay,

4:59

Gyroz, I've got everything out

5:01

under control. It's

5:05

trying! It isn't this button! That

5:12

was a close one. Okay, now

5:14

I don't want you to worry,

5:16

Gyroz. Still working out a few

5:18

kinks, the real prank will go

5:20

much smoother than that, okay? The

5:22

real prank? Yeah, it's the whole

5:24

reason I built this thing. It

5:26

was inspired by a new scientific

5:28

study from researchers at Seoul National

5:30

University in South Korea. They

5:32

built a giant, ten-foot-tall robotic

5:35

pranking dinosaur? Well, not exactly

5:37

a pranking dino. See, Gyroz,

5:39

their robot was based on

5:42

a dinosaur called the cadaepderix.

5:45

The cadaepderix? Wasn't that the dinosaur about

5:47

the size of a turkey? Yeah, a

5:50

tiny little turkey-sized carnivore that lived about

5:52

125 million years ago. Uh-huh,

5:57

so if that robot was about

5:59

the size of a... of a

6:01

turkey, then why is your robo-dinosaur

6:03

so much bigger? That's because our

6:06

prank victim is a little bit

6:08

bigger than what those researchers from

6:10

Seoul were after. What are you

6:12

talking about, Mindy? Well, the researchers

6:14

in Seoul were using their robo-dino

6:17

to prank locusts. Locusts?

6:19

Like the insects? Oh, why were they

6:21

pranking locusts? I'll tell you in a

6:23

second, Gai-Raz, but first I have to

6:25

get this robot ready for our pranking

6:27

victim. And who might

6:29

that be? Well, Dennis. Who else?

6:32

Oh, no, Mindy. You know what happened

6:34

last time you pranked Dennis. Yeah,

6:37

he loved it. Exactly.

6:39

And he kept on trying to get pranked

6:41

all week. He never stopped giving us suggestions

6:43

on how to prank him better next time.

6:46

Well, this time we'll be different, Gai-Raz. I'm

6:48

almost maybe sure of it. All

6:51

we have to do is get

6:54

this giant robot dino quietly over

6:56

to Dennis's house. Sneak it up

6:58

behind him, and then bam, spook

7:01

his socks off. Are

7:03

you sure this is a good idea,

7:06

Mindy? Yes, of course I'm not sure

7:08

this is a good idea, Gai-Raz. All

7:11

right, I'm booting up the robo-dino again.

7:13

Oh, no. Now everyone, stand back. Here

7:15

we go. In three, two,

7:19

one. See?

7:24

Totally fine. Mostly

7:29

fine. Come on, everyone. We've

7:31

got a prank to pull off. All right.

7:33

OK, now I just got to wheel this

7:35

big boy out of the lab here. Push.

7:41

Push. Push.

7:44

Push. Opening

7:48

the door. Mindy,

7:50

this thing is not going to fit out the

7:53

door. OK, come on. Easy.

7:55

Easy. Wow.

8:00

There we go. Ah. Mm.

8:03

So Mindy, remind me again about the

8:06

scientific study that this robot's based on?

8:08

Oh, yeah. I forgot to show you

8:10

the best part of the robot. You

8:12

did? Yeah. Check this out. I just

8:14

need to press this button here and

8:17

voila. Oh,

8:23

boy. Mindy. Wait. Ah,

8:25

no! No! No, no, no,

8:27

no, no, no, no, no. Man,

8:30

now I've got to fix another wall.

8:33

Mindy, are those wings coming out of

8:35

the side of your robot? Yeah. They

8:37

sure are, Guy Roz. Where did they

8:40

even come from? Oh, they were tucked

8:42

into its side, kind of like a

8:44

chicken. You know chickens are a direct

8:46

descendants of dinosaurs, right? Right. In fact,

8:48

dinosaurs were some of the first animals

8:50

to develop feathers. That's right. Feathers and

8:53

wings. Wait. Is that

8:55

why you have two massive flaps

8:57

hanging out the side of your

8:59

giant robot dino chicken? Yes. And

9:01

one of them is currently stuck

9:03

in the side of my gingerbread

9:05

mansion. Let me just retract those

9:07

back in here real quick. So

9:13

what do these wings have to do with

9:15

the scientific study, Mindy? Well, for the longest

9:17

time, scientists haven't been able to figure out

9:19

why dinosaurs developed wings in the first place.

9:22

They haven't? Nope. But there are some theories.

9:24

Well, like what? I'll tell you on the

9:26

way to Dennis' house. Come on. Hop on

9:28

the robo dino and I'll drive us there.

9:30

Huh? Here, let me give you a little

9:33

boost here. Well, uh. There

9:35

we go. OK. Now

9:38

make room for Mindy. Uh. All

9:42

right. Everyone on board? Yep.

9:45

OK. Next up, Dennis'

9:47

house. Giddy up. Whoa.

9:50

Whoa. OK, Guy

9:53

Roz. So there are three possible

9:55

theories for why dinosaurs developed wings.

9:57

And a theory is a guess.

9:59

that scientists have before they start

10:02

to conduct research to see if

10:04

the guess is actually correct. Exactly.

10:06

OK, so theory number one. Dinosaurs

10:09

developed wings to help them make

10:11

sharp returns and jump higher, which

10:13

would have helped them when they

10:15

were hunting prey. OK, and what's

10:18

the second theory, Mindy? Theory number

10:20

two, that dinosaurs may have used

10:22

their wings to keep their eggs

10:25

warm. And presumably, keeping their eggs

10:27

warm is important because it helped

10:29

the baby dinos inside develop and

10:31

grow. Exactaritos, keeping their eggs at

10:34

a warmish temperature, was extremely important

10:36

to their survival as a species.

10:38

Got it. And theory number three,

10:41

dinosaurs may have used their wings

10:43

to attract a mate. Huh, I

10:46

guess it's sort of like how

10:48

male peacocks use their colorful wings

10:50

to attract a female mate. Exactly.

10:53

So what does this have

10:55

to do with this robotic dinosaur riding?

10:58

Well, those scientists from the University of

11:00

Seoul have suggested a new

11:02

theory as to why the dino

11:04

got its wings. And what

11:06

is it? Oh, I'll tell you in a second. Looks like

11:08

we've made it to Dennis's house. All

11:11

right, everyone. Time to dismount. Ah.

11:15

All right, Reg. Hand me

11:18

my wow-noculars. Your wow-noculars? Yeah,

11:20

they're just like regular binoculars,

11:22

only wow-er. Uh-huh.

11:24

Just see what our good friend

11:27

Dennis is up to here. Focus,

11:30

focus, focus. Dennis,

11:34

where are you? There

11:37

he is, snooping in the backyard,

11:39

just as I had expected. Let

11:42

me just bring up the audio here. That

11:46

is a tea-tanity-tam. Oh,

11:48

my prize-winning azaleas. You're my

11:51

best friends. But don't tell

11:53

Mindy, or Reg. Or

11:55

Mother. Well, obviously,

11:57

don't tell Guy Raz. Huh?

12:00

Looks like we're all set for our

12:02

prank, Gyroz. No! Hee hee

12:04

hee hee hee! Ha ha ha

12:06

ha ha! Wait, Mindy. First, you need

12:09

to tell me about this new theory that

12:11

researchers came up with to explain how the

12:13

dino got its wings. Oh, right. Two

12:16

words. Flush pursuit. Flush

12:20

pursuit? I think

12:22

I've heard about that before, Mindy. Isn't

12:24

that a hunting strategy that

12:27

some birds use to catch

12:29

insects? Yeah, exactly. They spread

12:31

their wings super wide, and

12:33

then they slowly walk through

12:36

some tall grass. And

12:38

then they catch all the insects

12:40

that come jumping out. Uh-huh. Here,

12:42

I'll show you. Hey, Reg, can

12:45

you demonstrate? So

12:47

first, the bird spreads its wings

12:49

as far as they can go.

12:53

Perfect. Just like that, Reg. And

12:55

then they slowly walk through the

12:58

tall grass where they usually do

13:00

their hunting, use that patch

13:02

of grass over there, Reg. And

13:05

here's the coolest part. Insects,

13:07

like locusts, when they see large

13:09

animals approaching them, automatically jump up

13:12

in the air. They can't help

13:14

themselves. It's like trying to control

13:16

a sneeze. OK. So

13:18

the bird uses this to its advantage.

13:21

It makes itself look as big as

13:23

possible, and it waits for these insects

13:25

to jump out of the grass and

13:27

then snatch them up as a tasty

13:29

treat. Look, there's one

13:31

right now. Get it, Reg. Ouch.

13:36

Ow, way to go, buddy. You got it. How'd

13:38

it taste? Needs a little

13:40

salt? Wait, so these

13:42

researchers from the University of Seoul think

13:44

that dinosaurs might have developed

13:46

wings for the same reason, to

13:50

scare bugs out of the grass?

13:52

Exactly. And so now

13:54

you're trying to see if this bug-scaring

13:56

theory also works on Dennis?

13:59

Not your boy. picking up what I'm putting

14:01

down, Gyros! Okay, let me just

14:03

put on my wow-noculars here. Looks

14:06

like Dennis is finishing up his

14:08

morning snoop. Huh,

14:10

what's Grandma G-Force doing? Is she giving

14:12

Colonel Toot's Thunderpaw a bath on a

14:15

Tuesday? That's unusual. I better write it

14:17

down in my snooping journal. What

14:19

in the... Yeah, it's a snooping journal. Okay,

14:22

it's now or never. Time

14:24

to deploy the RoboDino.

14:28

These are the basic safety techniques,

14:30

also known as Colonel Toot's Thunderpaw,

14:32

also known as Toot's Magook. All

14:34

the help... Okay, we're in position. Now

14:37

it's time to unfurl the wings...

14:40

And...unfurl! So

14:44

the question is... What

14:46

was that? A

14:50

giant robot dinosaur! Father!

14:53

Your horoscope was right! Aaaah!

14:57

Got him! Well,

14:59

I suppose you could call that

15:02

a success? Oh yeah,

15:04

major successful scientific prank.

15:06

Were the researchers from the University of

15:09

Seoul as successful with their robotic dinosaur?

15:11

Oh yeah, they ran a bunch of

15:13

tests with their turkey-sized robotic dinosaur, or

15:15

they rolled it through a patch of

15:17

grass with a bunch of locust insects

15:20

hiding in it. Okay, and what did

15:22

they find? And they found that when

15:24

they rolled the robot through the grass

15:26

with its wings extended out... Like in

15:29

a flush pursuit?

15:31

Exactly! When they used

15:33

the flush pursuit hunting technique,

15:35

they found that tons more

15:37

locusts jumped out of the grass

15:39

compared to when the RoboDinosaurs' wings were tucked

15:42

in! Huh, so it's

15:44

definitely possible that this is

15:46

one of the reasons that dinosaurs developed

15:48

wings. It made them better hunters! That's

15:50

right. And not only because it made

15:53

them more agile and able to jump

15:55

higher, but because they could use their

15:57

wings to flush out insects from tall

15:59

grasses. like a lot of modern day

16:01

birds do. Brrrrr! Huh. But

16:04

we don't know for sure, right? Well, yeah. I

16:06

mean, these dinosaurs lived like 125 million years ago,

16:10

so there's no way to know for

16:12

certain, but it's a pretty fun theory.

16:14

Brrrrr! Well, we should probably go tell

16:16

Dennis that this was all a prank and

16:18

that there isn't a ten-foot-tall robotic dinosaur

16:21

chasing after him. Yeah, let me just

16:23

plug into the loudspeaker on the RoboDino.

16:26

Ahem! Ahem! Testing! Roar! Uh,

16:29

Dennis! Hello! You can come out

16:32

now! Ahh! Hello!

16:37

Mr. Robot Dinosaur? Did

16:39

you just say something? It's okay, Dennis.

16:41

It's just me. Wow! Mr. Robot Dinosaur,

16:44

you sound a lot like my friend

16:46

Mindy. It is me, Dennis!

16:48

Look! Over here!

16:51

Oh, hey, Mindy. I was just talking about

16:53

you with Mr. Robot Dinosaur here. How'd you

16:56

like the prank, Dennis? Prank?

16:58

What prank? It was a prank,

17:00

Dennis. We were using this giant robot to

17:02

get a scare out of you. And

17:05

it worked like a charm. What?

17:07

You mean Mr. Ten-Foot Robot Dinosaur here

17:09

isn't trying to eat me? No! Ahh!

17:13

A prank! Ha ha ha!

17:15

You know, I'm a very

17:17

popular prank-y. Told you

17:19

he'd love it, Guy-Roz. People love

17:22

pranking me because I have the best reactions,

17:24

but I have a few recommendations for

17:26

you. And

17:29

I told you he'd have a few suggestions.

17:31

First, Mr. Robot Dinosaur needs a

17:33

hat. Bye, Dennis! See

17:35

you later, Dennis. Hi, Robot Dinosaur's name

17:38

protection. Plus, I think it would look

17:41

very handsome. That's a tough kid. Wow
