"Ghost Busted."
That goes right there, and this goes right here
and ta-da! A crescent moon.
Out-of-this-world design, Iggy. It goes perfectly with my moon nightlight.
Pretty!
Oh, I brought something too! My dino-snore machine.
"Dino-snore machine"?
Uh-huh. The soothing sound of dino snores helps me fall asleep.
Whoa!
-My ears! -Whoa!
But maybe T. rex snores aren't the best for sleepovers.
This isn't just any sleepover.
It's our first one in this house.
My dad used to have the best sleepovers here when he was a kid. Right, Dad?
My friends and I had some epic hangs here.
We'd play ping-pong, eat yummy snacks
and tell spooky stories.
What kinds of spooky stories?
Oh, like the one about the Boogeyman of Broadway.
I love that one!
Um, I don't think we'll sleep if we tell spooky stories, right?
And, uh, sleep is kind of a big part of a sleepover. It's in the name!
We'll save that story for another time. Like over waffles tomorrow morning!
What should we do first?
Oh, right, this is your sleepover.
I'll just, uh, go read or something.
-'Night, Dad.
Thanks, kiddos. Come get me if you want to play--
if you need anything and have fun and get some sleep.
Okay, Dad.
So what should we do
to make this the funnest, most unforgettable sleepover ever?
Why don't we do something your dad used to do?
Eat yummy snacks? Way ahead of you. Catch!
That is a yummy snack.
I was also thinking we should play ping-pong.
Love that idea! Let me just limber up first.
No way. No ping-pong.
-What? Why? -Oh, come on! I'm all warmed up.
We can't play.
Dad's old ping-pong table is in the basement.
-Why can't we go in the basement? -It's haunted. There's a ghost!
"Haunted"?
Really? Tell me everything.
What does it look like? Its name? How tall is it?
You talk to it? Can it float through walls?
Does it go "boo"?
Oh, I haven't exactly talked to it or seen it
because I've never actually gone down to the basement.
-Huh? -What? Why?
-It's too spooky. -How do you know there's a ghost?
Sometimes, I see the lights flicker on and off,
and then a scary voice says, "Howler's hungry."
The ghost's name is Howler? Cute!
It seems we don't have enough evidence to know that the basement's haunted.
-Aww, phooey! So there's no ghost. -I'm not saying that.
Sometimes, things that seem spooky have logical explanations.
-I know what we should do. -Something super safe and not scary?
No, find out if there's a ghost in the basement!
I was afraid you'd say that.
I think it's time to haunt our brains with ideas.
We need a brainstorm.
What if we invite a ghost over?
The new ghost can go to the basement, tell us if there's another ghost.
But then there would be two ghosts.
Iggy's right.
Two ghosts could be a problem 'cause they might not get along.
You don't want ghost drama in your house. Trust me.
What we need is a way to see ghosts even when they're invisible.
We should make ghost goggles. I've always wanted my own pair.
Ghost goggles! How do we make them?
Based on what I've learned from ghost research,
we'd need aluminium, glass and purple space gas.
We need to trip through the galaxy to find some.
I think our sleepover would be over by the time we got back.
What if we design a ghost-sucker-upper
that sucks up the ghost and traps it there forever?
That's not very nice. We don't support ghost cruelty here.
I didn't think about that!
I don't want to hurt anyone, even a ghost.
We need to tackle this with the scientific method.
♪ Scientific method! ♪
♪ We have an observation ♪
♪ So we'll start with a question ♪
-♪ Research ♪ -♪ A hypothesis ♪

Iggy's observed spooky things coming from the basement.
And we have our question. "Is a ghost causing the spookiness?"
So next, research. I know tons about ghosts.
According to legends, ghosts make the temperature really cold,
show up in photos as balls of white light,
make electricity go bonkers,
and if you smell something weird, there's probably a ghost around.
Excellent ghost research, Rosie.
A hypothesis. If we build a device based on what we know about ghosts,
we'll be able to tell if there's one in the basement.
Yeah, we could call the device "the Spooky Scanner."
-Sounds scary, but also kind of cool. -And it's ghost friendly.
Loading the lab.
We can use this thermometer to see if the air gets really cold.
And this old baby monitor will help us listen for weird noises.
Anything spooky, we'll click this remote, so the camera will take a photo.
-Maybe it'll take a picture of the ghost. -We'll be ghost photographers.
Fa-boo-lous!
Now let's build this thing.
We have to put the scanner down there so it can collect evidence.
This is not how I pictured this sleepover going.
All right, let's ghost. I mean, let's go.
This seems like a good place.
It's chilly down here,
but not ghostly cold, more like jumper weather.
Howler's hungry!
The ghost!
-Iggy! -What was that?
I don't know, but I'm out of here!
I told you it's haunted!
-Oh, I know! Best night of my life! -That was definitely spooky.
But we don't have enough evidence to prove it's a ghost.
-The baby monitor! -What's that?
Howler's hungry!
See? Howler's hungry. I'm too young to be ghost grub!
Smile for the camera, Howler.
Ooh, I hope we got a picture of him.
-Let's go collect our evidence. -We have to go back down there?
-Yep. -Yeah!
Fine! For science. Huh?
Is it just me, or did it get a lot colder down here?
And a lot foggier!
It's not just you.
-This basement is officially ghostly cold. -Let's check the camera.
-A ball of white light, just like a ghost. -Um, what's that smell?
Garlic!
Weird smells! There is a ghost down here!
-Dad! -Whoa, there! What's the matter, kiddos?
-The basement's haunted! -Really!
There's a ghost down there, and even I got a little spooked.
A ghost?
We have all the evidence to prove it.
-Look! A blurry white ball of light. -And it's so cold.
And the electricity is going bonkers.
-We smell garlic! -The ghost's name is Howler!
"Howler"? Oh, that must have been really spooky.
But I think I have an explanation, and it doesn't involve a ghost. Follow me.
There's a bad fuse here I've been meaning to fix.
That's why the electricity's been wacky.
Howler's hungry!
It's okay, kiddos. Look around.
Wow!
This is where my friends and I used to hang out.
We loved playing the games in here, like this.
It's called Howler's Hungry.
Wait. Howler's not a ghost? It's a video game?
Yeah!
Someone must have knocked over this cooler.
That's why it's so cold and foggy.
Oh, I think that was me.
Look, the camera took a picture of a ping-pong ball, not a ghost!
Aha! The source of the garlic smell was garlic.
Whoopsies!
Our hypothesis was so wrong.
Aww, phooey! There's no ghost down here.
Some of the evidence just made it look like there was.
A new theory. The Ghost in the Basement Theory.
Gathering evidence without looking at all of it can lead to false conclusions.
Smart theory. Now you know the basement's not haunted,
I'll leave you to your sleepover.
-Want to play some games? -You bet I do!
-Come on! -Yes! Come on!
-Oh, move! What?! -Howler's hungry!
-Yes! -Fab-tastic hit!
Wait, I did it? I won?
Way to go, bud! You're going to beat my high score.
I've got to say, even though I didn't meet a ghost,
this is still the best sleepover ever.
Oh, yeah! It's one we'll definitely remember forever and ever.
I guess our first sleepover in this house was pretty epic.
And now I'm not scared of the basement.
-Howler's hungry! -I'll get used to that… eventually.
"A Cold-Blooded Complication."
Yeah!
Yee-haw! I'm so close to winning.
Nice jump!
Okay, it's down to Rosie and Iggy,
playing for a once-in-a-lifetime chance to win--
Ooh, candy floss!
Thought you were playing for a chance to watch Lil' Liz
while Arthur's at his tournament.
-No! I mean, look at all that candy floss! -Oh!
Are you having giants over for a party, Mr. T?
Totally makes sense. They have a huge sweet tooth.
That candy floss looks so good!
Whoa, there, Rosie. This is fibreglass, not candy floss.
Insulation to keep the garage warm. Want me to teach you how it works?
Do you kids want a once-in-a-lifetime chance to watch Liz or not?
Cool. Insulation's cool.
You're up, Iggy.
I'm nervous.
Don't sweat it. Make sure your knees are high.
Focus on the square and str--
My jacket!
Ooh, yikes.
Sorry. I know that's your favourite jacket.
Oh, man! It's ruined! I guess I've got to throw it away now.
Maybe you can make it into something else.
Scientists find new uses for old stuff all the time.
Make it into a denim racquet bag.
-A top hat for magic tricks! -A hammock for Lil' Liz!
Now, that I could get behind. But I just want my jacket.
Going to play with Lil' Liz. She always makes me feel better.
I feel Arthur's pain.
I was super-duper sad when I got a hole in my favourite unicorn T-shirt.
I remember. We had to have three dance parties to cheer you up.
Lil' Liz!
-What's wrong? -Lil' Liz's blinks per second is way off.
She should have eaten her bugs and berries,
and she's moving really slow.
Step aside. I speak lizard.
That's lizard for "What's wrong?"
Weird. She's usually so talkative.
Hmm, this is…

We need to get answers.
With science! To the lab, stat!
Lil' Liz is going to be okay. Right, Mooshu?
Loading the lab!
What should we do first?
When I go to the doctor, they check weight and temperature.
And give you a lollipop!
Lil' Liz can't eat lollipops.
-Let's check her weight. -The pet scale!
-She's a healthy weight. -I'll check temperature.
She's cold.
Are lizards supposed to be cold?
Well, they're ectothermic, which means they're cold-blooded.
Warm-blooded animals can regulate their body temperature,
but cold-blooded animals, like lizards, turtles and bees can't.
When we get cold, our body shivers to warm us up.
When we're hot, we sweat to cool down.
-Mind blown! -But lizards can't do that.
If Lil' Liz can't heat up, how can she get warm? Is she gonna be okay?
She can be cold for a while.
She has to get warm from heat sources like the sun
or the light bulb in her terrarium!
I think we connected the polka dots. Let's get Arthur.
-You figure out what's wrong, Ada? -Yep, she's cold.
The light in her terrarium that keeps her warm is out.
That's why she's not eating or playing.
Or talking!
Whew! That's all? I have another bulb in my room.
Be right back.
I had another bulb. I'm all out. And the pet store is closed.
-How are we going to get Lil' Liz warm? -We've got a plan B. Brainstorm.
I have an idea! When I work out with my mum, I get really hot.
We could design a mini gym for Lil' Liz.
Not going to work.
Lizards' hands and feet are like suction cups. Stick to stuff.
Cold-blooded animals can't regulate the heat inside their bodies.
What if we make Lil' Liz
a warm bowl of cricket noodle soup with berries?
Lil' Liz only eats live insects, and she doesn't like warm fruit.
I've got it! We could use dragon breath to heat a hot tub for her!
Dragons have a lot of free time in autumn. It's their off-season.
Dragon breath is probably too hot!
Definitely.
Yeah, true.
What if there was a way to use hot water
to warm Liz up without getting her too hot? Be right back!
Boom! Hot water bottle. You pour warm water inside. It heats up.
Those only stay warm for, like, 20 minutes, right?
And we need to keep Lil' Liz warm until the pet shop opens tomorrow.
Aww, snap! You're right!
If dad's fibreglass wasn't off-limits,
we could wrap Liz in that to keep her warm.
You're onto something.
Dad's using the fibreglass to insulate the garage.
So maybe we could insulate Lil' Liz's terrarium.
-Let's ask him what else we could use. -Insulation is so cool.
Here's what you need to know. Heat flows from warm to cold.
Insulation slows the flow. That's how places stay warm.
Things used as insulators, it just has to trap air and hold together in humidity.
That's water in the air.
That's right. Insulation's cool, right? Or should I say warm?
I love insulation and dad jokes.
She meant to say "cool" dad jokes.
Let's run tests to find the right insulation for the terrarium.
Insulation simulations?
Fab-tastic idea! What about candy floss?
It looks like fibreglass, but we can touch it.
-Plus, delicious! -Great idea. Let's test it.
While you test, I'm going to get Lil Liz's lounge.
Be right back, girl.
We need to find out if candy floss will trap air
and hold together in humid conditions.
So, let's test it with something warm and wet.
-We could fill a beaker with warm water. -Then wrap it with a test insulator.
I'll test the temperature at the beginning and end
to see if the water stays warm. Let's get our materials.
Candy floss is yum!
I mean, done.
Starting temperature, warm.
No air's escaping, so the candy floss must be trapping it.
-Oh, no! -But it doesn't hold up in humidity.
-So that's a fail. -Aww, man.
But this fail is still a win.
What if we use aluminium foil? My mum uses it to keep food warm.
Great idea.
Starting temperature, warm.
-No air's escaping. -Humidity didn't ruin the foil.
-And the water's still warm. -We're ready to insulate.
First, the hot water bottle.
Oh, my gosh, I think it's working!
I'll add the foil.
Lil' Liz is squinting. A lot.
Maybe the light reflecting off the foil is too bright for her.
Aww, phooey!
So far, our insulation simulations are a flop!
-I'm going to set up Lil' Liz's lounge. -Okay.
Why is it so hard to find an insulation material
to keep Lil' Liz's terrarium warm?
Whoopsies! Sorry, Ada. I think I just wrinkled your denim jacket.
Wait! My denim jacket. It keeps me warm when it's cold
and doesn't fall apart when humid outside.
So you want to make Lil' Liz a denim jacket…
I'll get right on it! What are you thinking?
Glitter sleeves? Furry collar? Rhinestone buttons?
We should test denim as an insulation material.
But we can't cut up my jacket. I guess it was a good idea.
Here. You can cut mine.
If you can use it to help Lil' Liz, the rip was worth it.
But I can't watch you rip it any more. So I'll wait outside.
-Thanks, Arthur! -Yes!
Starting temperature, warm.
-The denim's trapping the air! -It's holding up!
Ending temperature, still warm.
-I love denim! -Let's see if it works in the terrarium.
Denim's a great insulation material.
-Yee-haw! -I heard cheering. Did it work?
Thank you!
The kids made you all better with science and denim.
Speaking of denim, what should we do with these leftover pieces?
Welcome to the Twist Fashion Show,
featuring denim designs by Ada Twist, Rosie Revere and Iggy Peck.
Let's get this party started right! Oh, yeah!
That's it.
-You got it! -Oh, yeah!
Uh-huh! Sha-bam! Pencils!
Watch out now.
You boys have got it, but Lil' Liz is the real star!
-Yes, Lil' Liz! -Over here!
-All right! -Smile here!
-Over here. -That's the talkative Lil' Liz I know.
These designs are fierce, fresh and fabulous!
You were right about making things with my old jacket.
Yes, and denim as insulation is genius.
We could use so much more stuff. Cotton balls, newspaper.
My old sock. Ooh, okay. Maybe not my old sock.
Come on, Twist. Let's get it!
