[Ada speaking]
[Great Aunt Rose] A tug-of-war between me and the crocodile.
He had Franki Fly in his big ol' chompers.
-[Ada and Rosie gasp] -Oh no!
W-What did you do?
Well, I wasn't about to let him eat my favorite doll now, was I?
I knew I had to think on the fly.
So I kicked off my shoes and flung 'em into the river.
Whoa! [chuckles] Must be the crocodile story again.
[Great Aunt Rose] The splash distracted the croc enough
for me to grab Franki Fly out of his mouth but not before he ate her parachute.
-[Rosie] Wow! -[Ada gasps]
-Yikes. -Oh my gosh!
And that is the story of how Franki Fly lost her parachute.
Even without it, she's still the coolest doll I've ever seen.
Tell us more adventure stories, Great Aunt Rose.
Yes, please, Ms. Great Aunt… Ma'am.
Sorry, champs. Gotta run.
Can't be late for my weekly laser-tag showdown with the Riveters.
-Aw, man. -Okay.
Are you taking Franki Fly with you?
Nah. Franki loves adventures, but she's not much of a laser-tag gal.
Why don't you three keep her company while I'm gone?
[gasps] Really?
Uh-huh. I'll be back later
for a slice of that scrumptious banana bread your mom is making.
[chuckles]
-Take good care of Franki till then. -We will. Promise.
-For sure. -You bet.
[all cheer]
I can't believe we get to play with Great Aunt Rose's special-est doll.
I wish she still had her parachute though.
Then she could jump from high places like she used to.
Uh, Rosie, we're scientists. We can make her a parachute.
Oh yeah! Doy!
It probably needs to be lightweight, but strong.
-Hmm. -[Rosie] I got it!
We can make it with this laundry bag.
Boom. Parachute.
Ooh.
Get ready to jump, Franki Fly!
Wait! We should test the parachute before we drop it.
-To make sure it's safe for Franki Fly. -Totally.
I don't wanna break her. So what do we do?
Maybe we could find a test object to use in place of the doll.
Yeah! Like a crash test dummy.
Um, Rosie, my dad says that's not a very nice word.
[giggles] A dummy's something scientists use to test how safe stuff is for humans.
Like cars.
[crashing]
[Iggy] Oh!
Or in our case, we'll test how safe a parachute is for a doll.
Great Aunt Rose's favorite doll.
Can we just use one like that?
Well, he's way bigger and heavier than a doll.
Good point.
Franki Fly is small, so our test dummy should be too.
Okay, so we need something small and breakable
that we won't get in trouble for breaking?
Where are we gonna find something like that?
[cracking]
I think we found our crash test dummies.
-That works. -Perfect.
Hey, Mom, can we break these eggs for science?
Affirm! That's pilot speak for "yes."
Bring back the shells. I can use 'em for plant fertilizer.
-We will. -[Rosie] Thanks, Mom!
Loading the lab.
[thrilling music plays]
Say hello to our first crash test dummy, Eggward.
-He's cute. -Hi, Eggward.
Don't worry, Franki Fly.
We're gonna make sure this parachute is super safe before we put you in it.
Super-duper safe.
Super-duper-trooper safe. That's really safe.
Iggy, fire up the claw.
[Iggy] Let's see.
I think this is the right button.
Whoa! Oh no, no, no! Wedgie, wedgie, wedgie!
[Iggy grunts and groans]
-That was not the right button. -[Rosie and Ada giggle]
Now we're ready for drop test number one.
Hit it, Iggy.
This one's gotta be the right button.
-[splat] -Eggward!
-[gasps] Don't look, Franki Fly. -Aw, man.
Hmm. This crash test was really crashy.
The parachute fell way too fast.
Probably means there wasn't enough air resistance.
Great Aunt Rose says parachutes need a lot of that.
Hmm, air resistance?
I know I have something about that in my notes.
Oh, here.
That's a force that pushes against the moving object, like a parachute,
to slow it down.
But if air goes through the holes, there's probably not much resistance.
Makes sense.
I think we've got a hypothesis.

What's our hippocampus?
Uh, hippogriff.
Hmm. I mean, hypersniff.
Oh, phooey! [groans] You know what I mean.
[giggles] Our hypothesis is, if the parachute doesn't have holes,
then there'll be more air resistance and it'll fall slower. Let's test it.
Hmm, let's use this. See? No holes.
-Good thinking. -Nice.
Don't worry, Shelly.
This parachute is sure to have more air resistance than the last one.
Only one way to find out. Drop it like it's hot, Iggy.
Whew. Okay.
-[all sigh] -Oh, man.
Sorry, Shelly.
It fell slower, but not slow enough.
There wasn't enough resistance, but the parachute didn't have holes.
Maybe to create more air resistance, we need more parachute?
You might be onto something, Iggy. New hypothesis.
If the parachute is bigger, then there will be more air resistance!
Hope our new hy-poth-esis is right,
'cause Ewan McEggor doesn't wanna crack.
Release the chute, Iggy.
Oh, I'm so nervous, I can't watch. But I also really wanna watch.
-[Rosie] Yes! -Make holes in your fingers, Iggy.
[gasps] Amazing.
It's falling really slow.
-It worked! -Ewan McEggor didn't crack.
Our new hypothesis was right.
-Woo-hoo! Yeah! -Yeah!
-We did it! -[cracking]
[gasps] Oops!
Ewan McEggor got Iggy'd.
[all laugh]
Good news and bad news, Mom.
Bad news. Eggward, Shelly, and Ewan McEggor didn't make it.
You were good eggs,
and your shells will give my plants lots of nutrients. Thank you.
What's the good news?
I think we built a parachute that works.
Can we go and test it out on the balcony? Pretty please?
Oh, a flight test? Of course you can.
Have a good drop, cadets. I mean, kids.
-Awesome! -Ye-e-s!
Okay, Franki Fly, you ready to finally parachute again?
"Bet your balloons I am. Let's jump!"
One jump comin' right up.
[Rosie laughs]
[Ada giggles]
Yee-haw!
[grunts] It's workin'.
[sighs]
"I'm going so slow."
[grunts] This is gonna take forever.
[gasps] I'm off course!
-[Ada] Franki! -[Rosie gasps]
[Rosie] Franki Fly! No!
[Ada] Oh no. We didn't think about wind in our tests.
In the lab, you can control conditions like that.
But you can't control the wind outside.
[panting] Too late to worry about that now.
We've gotta catch Franki before she blows away!
That way!
-[Iggy] Over here! -[Ada] This way!
[panting]
That's it. Come to me, Franki.
No!
[sighs] I promised Great Aunt Rose I'd take care of Franki Fly,
and instead I lost her favorite doll.
We can still save her.
We don't quit. We've got grit, right?
Yeah! Remember when the crocodile was about to eat Franki Fly?
-Great Aunt Rose didn't give up. -[Rosie] You're right.
Great Aunt Rose would never let anything bad happen to Franki Fly,
and neither will I!
We might not be able to control the wind,
but we can follow it. Come on!
[panting]
-I see her! -There she is!
No!
I wish there was a way to make her fall faster to the ground.
[gasps] There is!
We can make a hole in the parachute to decrease the air resistance.
-[Iggy] It's too high to reach. -[Rosie] We have to think on the fly.
I love when she goes into engineering mode.
Me too.
Ooh, a slingshot? Genius.
[Rosie] Ready.
Aim.
Parachute!
-Right on target! -Perfect shot!
[Iggy groans]
We gotta catch Franki Fly before she hits the ground.
[Ada] Hurry!
[panting] Comin', Franki!
[Rosie grunts]
-[gasps] Got her! -[Ada] You did it!
Yee-haw!
Catch ya next week, ladies. I want a rematch, Betty.
Howdy, champs.
And Franki Fly.
Thanks for taking good care of her.
I didn't take good care of her.
We wanted to make her a new parachute, but she almost blew away.
But she didn't.
So you must have come up with a clever idea to save her.
Yeah.
I guess I did think of a pretty great idea.
On the fly.
Just like I taught ya. And what an impressive parachute.
I bet Franki loved her adventure.
Almost as much as she'll love her new owner.
Who?
-Me? You're giving Franki Fly to me? -Yeah.
A doll, just like a girl, needs adventures.
She's had tons of 'em with me.
Now it's time for her to have new ones, with you.
-Whoa. -Wow.
Oh my gosh!
-[Rosie grunts] -[Great Aunt Rose] Oh!
I thought on the fly and made this slingshot to get her down.
That's the story of how Franki Fly got her parachute back.
And how I got my new favorite doll.
-Love that story! -What an adventure!
Now, who wants to see her jump?
-Me, me! -I do!
[Great Aunt Rose] Go, Franki, go!
[Ada speaking]
-[Ada] There! -Ada, Iggy and Rosie are here!
-[Rosie] Hey, Ada! -Today's the day! Today's the day!
-Hi, Iggy. Hi, Rosie. -Hi!
Uh, what is that?
My snow-fort lab design. Like the McMurdo Station in Antarctica.
-McMur-who? -McMurdo.
The best scientists in the world go there to do experiments
in sub-zero temperatures.
Yep. And we've gotta build our fort today, 'cause I've been tracking the weather
and it won't be snowy like this again this winter.
Did you know the six main parts of weather
are temperature, atmospheric pressure, wind, humidity, precipitation…
That's rain, drizzle, sleet, snow, hail--
I think we get it. The wet stuff.
-[giggles] Yep. -Oh, and don't forget cloudiness.
I can't wait to do all our snowy experiments!
Snow dragons, snowball launchers…
The world's biggest snow cone!
You should check out our snow fort when we build it.
Maybe later. I'm gonna go practice in the garage.
Thanks to the snow you love so much, I have to pivot.
-Pivot? -Go in a different direction.
You're just kids, but sometimes things don't go as planned,
so gotta go to plan B. See ya!
-Bye, Arthur. -Bye.
-Ready, team? -[Rosie and Ada] Yeah!
Hold on, snowy explorers. [laughs] Support staff has to do a supply check.
Designs?
Check.
-Shovels? -Check.
-Snow-brick molds? -Checkity-check-check!
Double-fudge cocoa?
[all] Huh?
I got 'em. I'll keep these here for later.
Just need to find marshmallows. You're good to go.
-Thanks, Dad! -Thanks, Mr. T.
This is gonna be so cool.
Oh, I mean, so cold!
The weather didn't say anything about blinding snow.
Or wind. Are we in Antarctica?
Huh? Mom!
Whoops! Sorry, guys.
-[all giggle] -Totally cloudy.
This is a great place for our lab. Let's build.
[grunting]
[jaunty music plays]
[Iggy grunts]
-Cool! -Yeah!
It's even better in person.
Perfect.
Or brrr-fect?
[all laugh]
And with this guy on watch, no one's going to get in.
Wow! Cool snow fort, kids.
Uh, no one else.
Arthur likes our fort!
And he's the fort master.
Hey, Arthur, you can stay and hang in our snow fort if you want.
Brrr. No, thanks. I'm going back inside where it's warm.
Maybe Arthur'd wanna hang out in it if we added extra stuff.
Like a second floor or lookout towers.
Well, I'm ready to hang out in our fort just like it is. Let's go!
Right behind ya!
[Ada] How much snow equals the world's biggest snow cone?
How big is too big to determine if it stays frozen or falls apart?
Most importantly,
do I make it raspberry or blueberry?
As soon as I make my giant snowball launcher,
I can do battle with my snow dragon.
-What are you working on, Iggy? -Where's Iggy?
If I added more snow bricks,
the foundation could totally support lookout towers.
Hey, icicles aren't a part of my design.
-Why does that wall look like that? -[cracking]
[yelps] The dragon's alive! [yells]
Oh, phew.
It was just the ice grinding together when the wing fell off.
Wait, the wing fell off?
Ada, Rosie!
There you are!
[gasps] The sun's melting our snow fort.
Aw, man. Our snow fort got sunned.
So does that mean no snow-fort lab today?
Nuh-uh. It's today or never, remember?
Iggy's right. We're scientists. We don't quit. We can figure this out.
-Okay. So what do we do? -We need to keep the fort cold.
Maybe we could make snow.
-Yeah! -Great idea!
Loading the lab.
[thrilling music plays]
To make snow, we need very cold temperatures plus water.
I'll handle the cold temperature.
I've g-g-got the w-water.
Yeah! We've got snow.
-[Iggy] But it's melting. -Huh?
'Cause making snow only works if it's really cold outside.
-Hmm, true. -[Ada sighs]
Wait. When we're hot, we get in the shade.
I have an idea. Umbrellas.
We'll need a lot, but it's doable.
I'll design an umbrella shelter.
[jaunty music plays]
Perfect. I'll build it.
[jaunty music continues]
There.
[Ada] This should keep the sun's radiation from being absorbed by the snow.
Otherwise known as shade.
Phew. The fort's safe for now.
But we'll have to think of a more permanent solution.
Let's think inside where it's warm.
Well, I'd say it's cloudy with a chance of brainstorms.
Yeah!

Yetis love snow. Maybe they have some we could borrow.
It's a good thing I speak Yeti.
Yeti-yay-oh-oh-yeah!
[Ada] But yetis live so far away.
By the time they got here, the snow-fort lab would be all melted.
Icy what you mean. Get it? "I see" what you mean?
Because ice?
[all laugh]
I have an idea.
We could build a rocket ship to take the snow-fort lab
to the coldest planet in the solar system, Neptune.
Bonus! Neptune looks like a jawbreaker. Yum!
Mm.
Eh? Uh… Uh-oh!
[muffled] A little help, guys?
[giggles] Just need a little warm water.
[Rosie grunts and sighs]
But we'd have to go all the way to Neptune to get into our snow-fort lab.
Uh, what about a giant fridge?
Or an ice-cube machine?
Or maybe a freeze ray? Or popsicles?
Snow dragons!
Oh, man. I'm so stressed, I can't think straight.
[groans]
You all might wanna check on your fort. It's in pretty rough shape.
[all gasp]
-[Rosie grunts]. -Oh no!
The sun must have moved while we were inside.
How long were we brainstorming?
Aw. Why can't the sun just stay put?
Well, the Earth revolves around the Sun,
so it's always moving.
Maybe Rosie was right,
and we should just forget about the snow-fort lab today.
No! It's the last snowy day.
And I was gonna add a second floor and lookout towers.
We have to save it.
-[Rosie] Iggy, wait up! -[panting]
[Iggy grunting]
Stay, snow.
Come on, stop melting.
I know scientists never quit, but, maybe this is an exception?
We can build another fort, Iggy. This one's about to cave in.
[yelps]
-Yeah, you might be right. -[all gasp]
We can get out this way. Slide!
-[Rosie] Oh yeah! -[all] Whee!
[thud]
[Iggy] Aw, that wasn't supposed to happen.
Ada tracked the weather and Rosie's engineering was perfect.
Yeah, it was.
It's like a dragon breathed its hot breath all over our beautiful snow-fort lab.
Wait! Maybe not hot dragon breath, but a warm air front.
That's a warm air mass that replaces a cold air mass
that creates big changes in the temperature.
That can change anytime because of winds, storms, and air masses called "fronts."
How does that work?
Let's put on our imagination caps.
This is Ada Twist with the weather. We're in a cold front, folks.
[all shiver]
Oh, I'm cold!
But this just in. A warm front is headed our way.
Sometimes when my mom runs into fronts when she's flying,
she has to change course. Like now!
[all yell]
So your mom pivots.
Goes to plan B! Just like Arthur's practice!
Yeah!
-Uh-oh. -[Ada] Look out!
[all yell]
[all laugh]
Too bad I didn't have a plan B.
-Whee! -Nice slide, Rosie.
Wait. I have an idea for a new design.
Another snow-fort lab?
Nope. I'm gonna pivot.
Design something that's perfect for this.
[Ada] Whee!
-[Arthur] Woo-hoo! -[Iggy] Yeah!
This slushy snow park is so cool, Iggy.
I don't even mind being cold.
It's really cool, Iggy. Cooler than a polar bear's toenails.
Here's something to warm y'all up.
I know, I promised marshmallows, but we were out, so I went with plan B.
Whipped cream!
Thanks, Dad!
-Mm-mm. Mm-mm-mm. Yum! -Mm.
Plan B never tasted so good.
I just wish I had something to remember the snow-fort lab by.
-Hey, look what I have. -The picture you took earlier!
Yup. It really was a cool snow fort.
Thanks, Arthur.
No problem!
-Let's go! -Woo!
-[Ada giggles] -[Arthur] Woo-hoo!
Don't worry, Iggy. We'll make a snow-fort lab next winter.
Yeah!
Oh, and if the weather changes, I have a plan B.
Solar-powered ice maker.
[Rosie and Ada giggle]
-Yeah! -And a plan C.
A snow dome, 'cause heat rises.
And a plan D.
