[mysterious music playing]
Come on, please be a five! Please be a five!
-Aw, man! -It's a two. That's three less than five.
And that means… Roar!
You've been turned into a werewolf.
According to the rules of Goblins and Dragons,
you can't speak 'til your next turn.
You can only howl like a werewolf.
I can only howl?
I mean… Woo.
Iggy, werewolf howls are louder than that.
Put your back into it!
Ah, woo!
Ew!
[sniffing] Yuck!
[meows]
Something smells like goblins' breath.
[sniffs] That smell, it's terrible.
-[groans] Horrible. -Toe-curling.
We have to find out what it is.
-[Rosie] Huh? -Say what now?
This stink is a mystery, a riddle, a puzzle, a quest,
and we're gonna get to the bottom of it.
[sniffs]
-[sniffing] -[meows]
I don't smell it anymore. Where'd it go?
[sniffs] Oh! Now I smell something. It smells like--
Like the yummiest yumminess ever!
Does this mean my famous veggie soup smells good?
-So good. -Delicious.
What veggies are you using?
Oh, carrots, celery, tomatoes, onions, and garlic for extra deliciousness.
-Same ones for the salad too. -[sniffing]
Same veggies as the soup, but these barely smell at all.
[sniffing, groaning]
-The stink is back. -Yes! Let's follow our noses.
[sniffing]
Carpet smells carpet-y, but not stinky.
[sniffs, sighs]
Smells like reading.
-[sniff]s It's not Mooshu's litter box. -[meows]
It actually smells surprisingly okay.
Yeah. Kitty litter is designed to absorb icky smells.
And Arthur and I take turns cleaning it every day.
[sniffs]
[sniffing]
[all] Ew!
A-ha!
The source of the great stink. Arthur's tennis shoes.
-The grand slam of stink. -What are you kids doing?
We just made a fascinating discovery. You have stinky shoes.
I know. They don't smell when I wear them at tennis.
-Only when I take them off. -Great observation, Arthur.
Do you like having stinky shoes?
No! I don't want my shoes to make the whole house smell.
That's why I'm trying this.
Mom uses perfume to make herself smell good,
so maybe it'll make my shoes smell good.
Oh, a test! Can we observe?
I guess.
[sniffing]
It does smell like Mom.
[all sniff, groan]
But now the perfume is mixed with the stink,
so it smells like your mom plus stinky-ness.
[sighs] There's no way I can un-stink these shoes.
There's almost always a way to solve a problem with science.
Let's see if we can solve this one.
-Does that mean a brainstorm? -Ding! Correct!
Great, 'cause I have an idea.
Whenever I'm stinky, my mom makes me take a bath.
-We could give Arthur's shoes a bath. -I love bath time.
It's when I think of some of my best questions.
But wet, slippery shoes could be dangerous for Arthur.
-Oh! -True. We could put 'em in the dryer?
That might ruin the shoes.
Luckily, I've got another idea.
Since cat litter soaks up icky smells,
we could pour some in the shoes to get rid of the stink.
Good thinking,
but what if Mooshu thinks Arthur's shoes are her litter box?
Uh-oh!
-No, Mooshu! -I can't watch!
[gasps] I have another idea.
We invent a spray that gets rid of the smell.
Like a perfume. Yeah.
Except instead of making it smell like something nice,
we'd make it smell like nothing.
-A no-fume? -Precisely.
But we don't want to accidentally ruin Arthur's shoes,
so we can do our tests on this.
I outgrew it last year, so my mom said I could use it for science.
We just need to make it super stinky before we use it.
[sniffs, groans]
[meows]
[sniffs, groans]
Loading the lab.
[thrilling music playing]
[sniffs] Smells like success.
P.U. That is stinky!
I don't know if my nose can handle this much success.
Maybe your nose doesn't have to.
Sometimes, scientists need special equipment for certain tests.
-Now we're ready. Let's hit it! -Yeah!
[uptempo music playing]
[sniffing]
Oh, no.
That's the gooiest flop I've ever seen.
[gasps] It's a glop!
Or a floop. Maybe Arthur was right. De-stinking his shoes is impossible.
-[gurgling] -Sorry. That was my belly.
When's dinner? Your dad's soup smells so good.
I know. The salad's probably tasty too,
even though it doesn't smell as good as the soup.
Wait. Why doesn't it smell as good?
-It has the same ingredients. -I don't know why they smell different.
I just know that a hot, tasty soup makes my belly feel nice and warm.
Soups are hot. [gasps]
And salads are cold!
I know that look. Do you have a hy-potty-what-asis?
-[laughter] -Yup.

And our hypothesis is hot things smell more than cold things.
Can temperature really make things smell different?
Well, when it's hot,
your molecules move really fast and bounce around like this.
Pew, pew, pew!
Like a wizard shooting fireballs.
Exactly.
And when it's cold, air molecules move slower…
[slowed down] …like this.
[regular speed] So smells travel through the air faster when it's hot.
That's what I'm thinking, but there's only one way to find out.
Think cool thoughts, because it's about to get toasty in here.
Hoo-wee! Did we teleport to the sun?
Need… water. So… thirsty.
[gulping]
[sighs]
I love a nice dry heat.
Well, I think it's definitely hot enough to test our hypothesis.
-Ready for a sniff test? -I don't know how much stink I can take.
You can do it, Iggy. Come on. Let's go!
On the count of three. One, two, three!
-[all sniff, groan] -Ew!
That is the smelliest smell I've ever smelled.
And the stinkiest stink I have ever stunk.
Heat does make things smellier, but to prove our whole hypothesis,
we need to see if cold makes things less smelly.
Bring on the cold.
[shudders]
I mean, bring back the heat.
First, we gotta see if the cold de-stunk Arthur's shoes. Ready?
[trembling] So cold.
[sniffing]
It smells like… nothing.
It's not stinky at all.
-Which means we proved our hypothesis. -Does that mean we can be warm again?
[laughs] Yep.
[sighs] Much better.
[sniffs] Except now that it's not cold, Arthur's shoes are back to being smelly.
We need a way to keep his shoes cold when he's not wearing them
so they don't stink.
The solution is obvious. We freeze Arthur's shoes into giant ice cubes.
That would solve the stink problem,
but I think Arthur wants tennis shoes, not ice skates.
Oh, didn't think about that part.
Maybe he can keep them in the freezer?
Hmm, my mom probably won't like dirty shoes next to all the food though.
So what if we created a shoebox that's kind of like a freezer,
just for Arthur's shoes?
A freezer with an awesome design. We could make it look like an ice palace!
Brr-rilliant! Now let's get building.
[uptempo music playing]
[groans]
-What are you doing to my shoes? -We're freezing the stink.
[sniffs] Wait! I don't smell anything!
Because the cold air's keeping the stink from going all over the place.
You found a way to keep my shoes from smelling up the house?
-Sure did. -Yep.
That's amazing! Thanks.
You might be onto something with this science stuff.
[sniffs] What's that smell?
[gasping]
It smells delicious. Must be your dad's famous veggie soup.
[all sigh]
-Sure is. -Yep.
-Definitely. -Just the soup.
Nothing else, like shoes or anything.
Huh? Shoes?
[slurps] Mm. This soup really does taste as good as it smells.
The salad tastes great too.
[laughs] Thanks. Glad you like it.
And I'm glad this soup is the only thing smelling up the house.
-Me too! -[laughter]
Hmm. [gasps]
I have an idea. Let's meet another scientist. Come on!
Hi, I'm Rachel Dutton and I'm a microbiologist.
Today, we're gonna talk about what makes cheese stinky.
[Ada] Let's go!
We came to the cheese shop today
to get a closer look at some of the microbes
that actually make cheese both taste good and make it stinky.
Microbes are very tiny cells
that you would never see with just your eyes.
You have to use microscopes to see.
These microbes are found everywhere.
They're found in the ocean, in the soil, and on some of the foods that we eat.
A lot of what we smell around us in the world,
not just cheese, is actually because of the microbes.
-[Ada] Oh! -This particular microbe we're looking at
is one of the most common bacteria you find growing on cheese.
It creates a lot of delicious flavors,
-but also makes it stinky. -[Ada] Ew!
One of the things that cheese-makers do to control
how much microbes grow on cheese is control temperature.
So the warmer the temperature, the stinkier the cheese.
This cheese is a special type of cheese from France.
And these holes are actually from little tiny bugs.
Those tiny bugs are called cheese mites.
The mites will create interesting flavors and smells on the cheese.
It's not just microbes that make smells.
It's other organisms that live on the cheese.
-[mite] Hello. -Fun fact.
One of the microbes that grows on cheese and makes it stinky
is the same type of microbe that grows on our feet.
When people think stinky cheese smells like stinky feet,
it's because it's the same type of microbe growing
and producing the same stinky smells.
[laughs]
Wasn't that cool? Science is the best!
[Ada speaking]
-Mooshu's new cat toy is done. -Cool.
I calculated it so it's the perfect mix of curly and crinkly.
Let's see if she likes it.
[meows]
[Iggy] Yep. She loves it!
Especially the crinkly part. Why do cats love things that crinkle?
-Mooshu is so cute! -[Mooshu meows]
I wish I had a pet.
But since my mom travels for work, she says we wouldn't give one a good home.
I guess that makes sense. Taking care of a pet is a lot of work.
-But maybe you could get one that isn't. -Like a goldfish.
They just swim all day. You don't even have to walk them.
But you do have to feed 'em.
And they're hard to hug.
Maybe a monkey. They love to hug! And play.
-Maybe a little too much. -True.
Hmm. What about a ladybug?
You don't have to walk or play with them, and they're adorable.
But they need food and a space to crawl around.
Plus, they're easy to lose.
Here, ladybug.
True. You don't want to step on a ladybug that's lost in your house.
So you need a pet that doesn't eat,
doesn't need to play, and doesn't need hugs.
-Sounds like a rock. -[gasps] Yeah, I could get a pet rock!
I was kidding.
I wasn't. Let's get my pet rock right now!
-Hmm. We can find one in my backyard. -Hmm. Those rocks already have a home.
I want a wild rock that needs one.
But where could we find a wild rock?
[all] Hmm.
I know. The park!
Uh…
-Hi, Mom! -[gasps] Ada, you startled me. What's up?
I was going to ask you to take us to the park, but if you're working--
I am working… on this crossword puzzle.
-[laughs] Mom! -[laughs] I'm stuck on this work problem.
When that happens, taking a break does the trick.
Please let me take you to the park, so I can take a brain break.
Yay, we're here!
[giggling]
Here. This looks like a good spot.
Thanks, Mom. We're gonna look for some wild pet rocks.
Wild pet rocks? Okay, don't feed 'em. And stay where I can see you.
We will!
[giggling]
There are so many rocks here. I don't even know where to start.
[gasps] This one's blue and round. Oh, and shiny.
I love it! Definite maybe.
Check this one out.
It has fuzzy moss on top. It's so cute.
I love that one too.
Oh! These two look like twins.
Nice.
[gasps] This rock with this cool chip rocks!
So many choices. Let's keep looking.
Whoa! Rosie, that's a big pile of possible pets.
Yeah. How do we choose which one to take home?
Rock, paper, scissors?
I could never choose just one!
There's something special about every rock.
Like Mossy.
So fluffy and cute.
So cute.
Rocko and Milla are brother and sister.
I can't separate them.
And Chippy has a chip.
No one else will ever want him.
But me.
So I have to take them all.
Okay. There's just one problem. How are we gonna get 'em home?
Easy. In our pockets.
I can't move my legs!
They're really heavy. [screams]
Okay, not our pockets.
Maybe I can use my scarf.
Stay.
Who's a good rock? You're a good rock.
[groans]
They keep falling out.
Guess 'cause they're wild. Training'll be a doozy.
Hmm. Know what we could use?
I know! A brainstorm.
Great idea.

Hmm. What if we poofed the rocks home? Chabra kadabra.
Uh, I mean abrakazizzle!
But I can't remember the spell words, which might cause a bigger problem!
[screams]
What if we put your house on wheels and moved it here?
Hmm, I'd guesstimate we'd need roughly a zillion wheels.
Yeah, you're right.
We could get ladybugs to fly ants that carry the rocks.
Ants are strong.
But ladybugs aren't that strong.
[screaming]
Any other ideas?
[sighs]
Uh, I got nothin'. [sighs]
[gasps] Unicorns?
Hey, that's usually my line!
Ants, but no ladybugs!
[gasps] Unicorns.
I already said that.
Cheese.
Cheese?
I'm hungry.
Oh, no.
I think we ran out of ideas!
What? We never run out of ideas.
We need to keep brainstorming.
I have to get my pet rocks home!
But I can't think anymore. My mind feels like goo.
My mush is mind-y.
I mean my mind is mushy.
-What if my mind turns to mush forever? -What are we gonna do? We're stuck.
Stuck… Stuck!
What if we stuck the rocks to…
Oh, I don't know. [groans]
It's like my brain broke.
Wait a second!
I'm stuck on this work problem.
When that happens, taking a break usually does the trick.
I think I just connected the polka dots.
My mom's taking a brain break 'cause she was stuck on a work problem.
We're stuck, so maybe we need a break.
A play break.
No! We think should.
I mean, we should think. [sighs]
Okay, we can take a break.
[laughter]
Wee!
[humming]
-[Ada laughs] -[Iggy, Rosie gasp]
[giggling]
[giggling continues]
Oh! These sunflowers look like they'd make a pretty cool catapult.
[Iggy sneezes]
Who knew sunflowers were such a design…
[sneezes]
…wonder?
It's like there's little flowers inside the flowers.
There are. Sunflowers are made of thousands of tiny flowers.
[sniffs] They smell so good.
Hmm. Why do flowers smell so good?
Hey, my brain's coming up with information and questions again.
-And my mind doesn't feel mushy. -Our play break worked!
Yay. Let's get back to our brainstorm.
I know. We could charm owls into flying the rocks home for us.
I'm very charming.
Owls don't work during the day. They're nocturnal.
Oh, yeah, they're only awake at night.
We could make a roller coaster to carry the rocks.
I love that idea.
But what if the roller coaster's wobbly and the rocks roll out?
Then it would be a rock and roller coaster!
[all laughing]
Maybe we can build something so we can haul the rocks.
Yeah. We could call it a Rosie Rock Hauler.
Great idea. Let's build it!
It could have a big net for the rocks.
-And a frame to hold 'em in. -And wheels.
And done.
-Love it. -Nice!
Let's get materials.
Hmm… [gasps]
We can weave vines together for the net.
-These sticks will make a nifty frame. -Found these wheels around the park.
Can I build it now? Can I? Can I?
-Yes. -Go for it.
-[squeaks] -[laughter]
Yee-haw! We've got a Rosie Rock Hauler.
-It's perfect. -Good job, Rosie.
Thanks. Let's see if it's strong enough for my pets.
Yay. It is!
Let's finish loading.
[all groaning]
[doorbell ringing]
-[Mrs. Twist] Hi. -Hello.
-How was your flight? -Wow-wee!
That flight was a doozy.
-Come on in. -[gasps] Mom!
Hey, Rosie-posy-puddin'-pie. How was your day?
[grunting, blasting]
I got pets. Lots of 'em!
You what?
It's not what you think. Come see!
-Meet my pet rocks. -[sighs]
That's Chippy.
This is Rocko and Milla.
And here's Mossy.
[laughs] I never thought we'd be able to have a pet with my travel schedule,
but rocks?
Creative.
Attagirl.
Right? These three are the best at thinking their way out of problems.
We did run out of ideas, but then we took a play break,
like your brain break, Mom, but with playing.
-You were right. It did the trick. -I'm glad that helped.
So let's take your pets home.
Okay, but first…
You should take the blue one, Iggy. You bonded.
Thanks, Rosie!
And take Mossy, Ada. You're perfect together.
-Really? Thanks! [gasps] -[Mooshu meows]
Don't worry, Mooshu.
I may have a pet rock, but you're still my favorite kitty.
[all laugh]
[meows]
Hmm… [gasps]
I have an idea. Let's meet another scientist. Come on!
Hello.
Hi, I'm Raquel Nuno and I'm a planetary scientist,
and today we are going to talk about rocks from space.
When we think of rocks,
you think of rocks that you find at the park or on your hike,
but there's lots of rocks just floating around in space.
At some point, they entered our atmosphere and crashed onto the surface of the earth,
and now we have them here in our meteorite gallery.
[Ada] Oh!
Rocks that came from space and then landed on Earth, we call those meteorites.
These are our massive iron meteorites here.
If you're out rock hunting,
one of the ways that you know that you've found a meteorite
is by seeing if it's magnetic.
[Ada] Wow!
The rocks here on Earth are usually not magnetic.
The types of rocks floating around in space,
they range from something as small as a speck of dust
all the way to something as big as almost a planet.
The earth is essentially just a big rock floating in space.
[Ada] Whoa!
You can actually see space rocks coming in to Earth.
Meteor showers.
They're tiny pieces of dust and rocks that enter our atmosphere and burn up.
We see them as bright streaks across our sky.
Don't forget to look up next time you're outside at night.
You might just catch a meteor shower.
Fun fact.
The moon is shrinking.
It turns out that inside the moon there are rocks that are hot,
but as they cool off, they shrink,
and so the whole moon is getting smaller.
Don't worry. You'll still be able to see it.
Wasn't that cool? Science is the best!
[closing theme music playing]
