"The Giggle Bug."
Stop! You can't eat that.
Uh, why not? I really want to eat it.
You can, but not yet.
We haven't gone round the table to share a fun fact.
Right, well, today I learned that after a long day at work,
I'm really hungry for tacos.
Dad, that's more of an observation than a fun fact.
-Okay. Honey, what's your fun fact? -Hmm.
Well, today, I read that the first-ever website was created in 1991.
That's a long time ago.
Basically ancient.
So long.
I have a fun and fascinating fact.
It's fun-scinating.
Yawns are contagious.
That fact is fun.
If I yawn or even talk about it, the Yawn Bug'll probably infect you.
-That's how the brain reacts to yawning. -Isn't the brain…
fascinating?
See? You got bit by the Yawn Bug.
Oh, man, my taco!
What's your fun fact, Arthur?
Hmm. I'm observing a strange phenomenon.
Arthur doesn't seem excited about taco night.
He's mumbling instead of talking,
and he's wearing his grumpy bear slippers,
which he only wears when he's sad.
Arthur is sad.
Why are you sad? How long have you been sad?
-When are you going to stop? -I don't want to talk about it.
The Kid Magicians Show was cancelled.
Oh, no. Been looking forward to that for seven months.
-Three weeks, four days and nine hours. -I know.
I even learned a new trick, all for nothing.
It's normal to be sad, baby. You just need to feel your feels.
Right. Feeling emotions is important.
We all feel sad sometimes, and that's totally okay.
-I'm feeling them. They all feel sad. -Here's another fun fact.
Did you know that you can work at being happy?
Hold up. Work at being happy?
Just like being good at science or tennis takes work, so does being happy.
Yep. Know why your dad and I dance around the house all the time?
-It makes us happy. -Let's show them.
Work those ancient '90s dance moves, Twist.
Yeah.
You could do something that makes you happy.
I want to be happy,
but I don't feel like doing anything now.
Can I go to my room? I'm not in the mood for tacos tonight.
-Sure. -Sure, lil' man.
Wow, Arthur really is sad.
He always finishes his tacos and mine.
Need to give him time to work through his feelings.
I always feel happy after a good night's sleep,
so maybe Arthur will feel better by the morning.
This is going to be another fun-tastic day.
Oh, no, Arthur's still sad. I've got to do something.
Arthur's sad? That makes me sad.
Being down in the dumps can be a real dump.
I wanna help Arthur. Let's start with something that always makes me happy.
A happy storm?
I mean, a brainstorm.
-Yay for happy brainstorms. -I've got an idea.
We could design a gigantic Arthur statue that looks over the whole neighbourhood.
-That'll make him happy, right? -That'd take up too much airspace.
-It could be dangerous. -Watch out!
It would take a long time to build. Maybe a faster way,
like turning on a happy switch in his brain.
Awesome! I didn't know the brain had a happy switch.
I don't know if it does. I was kind of just hoping.
I've done some research on brains, so let's see.
Nope. No happy switch.
Turns out the brain's more complicated.
I know, a Pegasus!
You can't be sad flying on a magical winged horse.
Arthur would have no idea how to ride a Pegasus.
-What if it starts bucking like a bull? -Hilarious!
Oh, boy! Laughing this hard makes my stomach hurt.
But it also makes my heart happy.
That's the answer. We need to make Arthur laugh.
My mum says laughter is the best medicine.
Let's see what the science says.
It's true.
Laughing releases chemicals that feel good, like endorphins.
-I think I have a hypothesis. -I knew you would.
♪ I've got a hypothesis ♪
-♪ Does that mean this? ♪ -♪ Right or wrong ♪
♪ Let's find out what the answer is It might not be right ♪
♪ But we're going to find out What this theory is all about ♪
-♪ Educated guess ♪ -♪ Stand up to our test? ♪
♪ That's what a hypothesis is ♪
♪ I've got a hypothesis ♪
♪ Let's find out how right it is ♪
♪ Let's go! ♪
Hypothesis, if Arthur laughs,
his brain will release feel-good chemicals and be happy.
-Awesome! -I love happiness.
So how do we make Arthur laugh?
Hmm. I've got an idea or two.
Get to your seat. Show's about to start.
What are you doing? What show?
The most gigglicious, comedy-tastic show you've ever seen.
Hope you got laughing pants on.
-It's about to get hilarious up in here. -Huh?
Good evening, Living Room!
Feels a little cold in here, doesn't it?
No worries, though, 'cause I'm here to warm you up!
Get it? Nothing?
Okay. I've got a knee-slapper for you.
What did the ocean say when he saw his best friend?
Nothing! He just waved!
Geesh! Tough crowd.
Arthur hasn't smiled, even a little.
Don't worry. We'll find a way to make him laugh. We've got to.
-Whoa! -Yikes!
Aha!
Uh-oh!
Ugh, I got pied.
Aw, phooey! I wanted to get pied.
Arthur, why didn't you laugh at any of our hilarious stuff?
-I just don't feel happy enough to laugh. -This is hopeless.
If Arthur doesn't laugh at Iggy getting pied, he won't laugh at anything.
Yeah, that was pretty funny and messy.
But also delicious.
You don't have to say it, 'cause I will.
That was a flippity-floppity-flop.
Couldn't get his brain to release "endolphins."
I think you mean endorphins.
Oh, right. Oopsies!
"Endolphins."
It wasn't that funny. I'm think I'm laughing 'cause you guys are laughing.
It's like laughter is contagious!
Maybe laughter is contagious!
Like how yawns infect you with the Yawn Bug.
Oh, yeah! Even hearing about yawning makes me yaw--
So maybe giggles can give you the Giggle Bug!
Sounds like the cutest bug ever.
And the happiest. We need to test to see if laughter really is contagious.
Loading the lab.
This machine will play sounds.
This helmet will show us if any cause happy chemicals in the brain.
So who wants to volunteer?
Pick me! I'd love to volunteer my brain for science!
Huh! Did not expect that. Go ahead, Iggy.
Ooh, my brain is blobby.
Okay, let's put it to the test.
Spooky sounds definitely don't make me feel happy.
Next, please.
Don't like this one either.
You know how I feel about birds.
A.
-Wait, is that-- burps? -B, C…
-And is that-- Rosie? -D.
Thought I'd shake it up.
None have released happy chemicals in Iggy's brain.
Let's see if laughter does anything different.
Ooh, Iggy's brain is colourful and sparkly.
Oh, I want a sparkly brain!
That's not sparkles. That's endorphins.
Hearing laughter does release happy chemicals in the brain.
Guess we proved laughter is contagious!
Now we just have to infect Arthur with the Giggle Bug.
The giggle what, now?
The Giggle--
I don't get it. What's so funny?
I can't even explain.
Iggy's sparkly brain!
I don't even know what you kids are laughing at, but now I can't stop.
Caught the Giggle Bug. It's releasing feel-good chemicals in your brain.
Yeah, the "endolphins."
I mean, endorphins!
They make you feel so happy!
So hearing you laugh is what made me laugh?
And laughing made my brain release happy chemicals?
-Exactly. -Crazy, right?
That's kind of cool! I guess I really needed a good laugh.
Thanks, Lil' A. And thanks, Rosie and Iggy.
I think I understand what Dad was saying now about working at being happy.
Looks like I'll work at it by doing more things that make me laugh,
like playing with this funny, pie-throwing whatchamacallit.
"Dance Dance Twist Solution."
Lil' Rivets, from the top. Five, six, seven--
Left foot, nine o'clock. Right foot, three.
Use the clock, but only if you forget the steps.
Feel the dance!
Oui, little darlings.
If you go off book, still dazzle, sparkle, shine.
-And spin and pose and done! -Huh?
All right, circle up, everybody. Lil' Rivets, you've practised a lot,
but remember, memorising the steps is only half the goal.
So 50% memorising and 50% what?
Don't worry about the calculations. Your brain knows the steps.
All you have to do is let your muscles remember 'em and have a ball!
Feel it in your bones and go with the flow!
-Let's show 'em what I mean, boss. -♪ Yeah… ♪
♪ Hey! ♪
Go, Great Aunt Bernice!
Now get some rest. Tomorrow's a big day.
-Toodle-oo! -See you on stage.
-Bye! -Later!
I'm nervous about tomorrow. What if I don't remember the steps?
What? You're a great dancer, and you've practised a lot.
-You've got this. -Yeah, you do.
But if you forget, just remember Rosie Rule number 82.
When in doubt, do a fab-tastic freestyle. Whoo! Yeah!
I can't freestyle.
This is special. I have to remember the steps.
-Later! -Bye!
Left foot, nine.
Right foot, three.
Left foot, nine o'clock.
Right foot, three o'clock. Left foot, nine--
I know you're excited about tomorrow, but your muscles need to rest.
Okay.
Good night, Mum.
'Night, baby. Sweet dreams.
Yeah!
Huh? Oh, no.
-Yeah! -My legs are moving funny.
This is a mystery, a riddle, a puzzle, a quack.
Quack!
Huh?
It was just a dream.
I'm not a rubber ducky. Still Ada.
Ada's the last one up? Huh, that's a first.
Did Ada and Arthur switch places while we were asleep?
No, I dreamt I was dancing.
My legs switched with duck legs. I turned into a rubber ducky.
Sounds like someone's nervous about the recital later.
You have been practising for weeks. You're prepared, sweets.
Even if you mess up, Mum and Dad will clap.
Arthur!
What did I do? That was nice.
Don't worry, Lil' A. I know you've got this.
-Why aren't you nervous? -I've got this.
Baby, could you pass me an apple?
-Me too. -Me three!
-Whoa! -Uh-oh.
How, Arthur? How'd you do that?
Muscle memory.
I've practised tennis so much that I don't even think about it.
Muscle memory. Fascinating.
Want to give us a preview? Might calm your nerves.
Okay, first, I picture a clock on the floor.
Left foot, nine. Right foot, two.
No, three.
Nine minus six-- whoa!
I forgot the dance steps!
Don't worry. They've got to be in that big brain of yours.
Just like forehands, backhands and coolness are in mine.
But where? My frontal lobe?
Temporal lobe? Cerebellum?
I don't know. You're the scientist.
But the recital's in a few hours.
I need to find out why I can't remember the steps and fast.
I need backup.
Don't worry, Ada. We're here now.
Yeah! Let's boogie into a brainstorm and help you remember the steps.
Thanks, guys.
Maybe we could switch my legs with octopus arms.
Each has its own mind, so they'll remember the steps.
But if each arm has a mind of its own,
they might each try to do different parts of the routine.
Yeah, that would be an octo-fail.
I know! What if we attach puppet strings to your legs
and ask a friendly giant to be your puppeteer?
That could work.
But what if the giant doesn't stick around?
-You told me they get distracted easily. -Oh, yeah. They do.
So much for that big idea.
Got it! We could make you a robo-suit and program the dance into it.
But what if it glitches on stage?
Oh, yeah, that could be a real mechanical meltdown.
A robo-dance suit might not work,
but it gives me an idea.
My dad has this really old game that has a dance pad
with arrows that light up so you know where to step next.
I see where this is going.
We can make something like that and program it with the dance routine.
Love it! Loading the lab.
Voila! The machine's done,
and the dance is all programmed in.
Remember, if you make a wrong step, it'll quack. You're up, Ada.
All right, Lil' Rivet, from the top. Five, six…
-…seven -Right foot, 12.
Left foot, oh, missed it!
Don't worry. Keep going!
Whoo! Get it, girl!
Whoo! I did the whole dance, and I didn't quack up.
Now doing the steps without the machine should be no problem.
Left foot, nine. Right foot, three.
Left foot, 12.
Right foot--
-Ada! -Whoa!
Why can't I remember the steps?!

Well, I'm as stumped as your leg muscles are, Ada.
I have no idea why you're forgetting the dance.
Wait a minute. Forgot muscles…
My legs lost their memory.
So, Arthur was talking about muscle memory this morning.
Great Aunt Bernice said brains know the steps.
So our muscles will remember. They were talking about the same thing.
-But how do muscles remember things? -Well, our brains control movements.
Ah, so maybe we need to take a trip deep into the caverns of our brains.
But I didn't pack.
Don't worry. All we need are our imagination caps.
Oh, that must be the frontal lobe.
That's responsible for speaking, right?
Uh-huh. There's the temporal lobe, for hearing and recognizing faces.
You guys, there's the cerebellum! It's responsible for coordination.
Oh, you need that for dancing.
I think that's where we want to go. Coming in for a landing!
-Hold on! -Coming!
How does the "Sarah-balloon" work?
Uh, I mean, the "cereal-Bella."
The cerebellum. Let's see.
It sends signals to muscles that help our bodies move smoothly.
The more you do a move, the better at remembering it.
That reminds me of when I was learning to skate.
It was really hard at first, but the more I did it, the easier it got.
Now I don't even think about it.
So, since I danced the dance a lot, my muscle memory should kick in.
-Come on, let's go back. -Let's see it, Lil' A.
From the top. Five, six, seven, eight.
Left foot, nine. Right foot, two.
Left foot, 12. Right foot--
I've practised and been thinking about the steps a lot.
Why isn't my muscle memory kicking in?
-Maybe you're overthinking. -Thinking's what I do.
Thinking's great, but overthinking can get in the way.
I'm not thinking about this apple and bouncing my ball. I'm just doing it.
You're right.
So overthinking is stopping me from remembering the dance steps?
-Interesting theory. -Makes sense!
Kids, let's go! We've got to get to the recital.
-Okay. -Let's get it!
Oh, stop. You shouldn't have.
Ladies and gentlemen, children and pets!
The Raucous Riveters present…
The Little Rivets!
Yeah!
That's my baby!
Don't quack up, Ada. Don't quack up.
Left foot, nine.
Right foot, three.
Oh, no! I'm quacking up!
Psst, Ada! Stop overthinking. Go with the flow.
-Yes! Whoo! -Yeah!
Bravo! C'est magnifique!
It was-- no, let me see if I have this correctly… lit!
Colder than a polar bear eating an ice cream cake! That was great!
You crushed that dance, like a tiny, little tin can.
Whoo! Lil' Rivets!
-Yeah, Ada! -You did it!
Great Aunt Bernice, I stopped overthinking,
let my muscle memory kick in. I felt the dance in my bones.
-I saw you out there. Whoo! You sure did! -Darlings!
They're demanding an encore.
Let's give the people what they want!
Yeah!
