- Did a word that's important to you go missing?

- And now all you can feel, do, or think is the opposite of that word?

- Then call us.

I'm Sly.

- And I'm Gabby.

We're word detectives, and we solve word mysteries.

- Word mysteries.

Together, we run the words of a online detective agency.

- We'll find your missing word fast.

- Not to mention, briskly.

- And swiftly.

- Yeah.

We're really good with words.

- [Sly and Gabby] "Wordsville"!

(cleaner spritzing) - Nothing like the smell of a lemony fresh work surface in the morning.

(sniffs) Sly, something's wrong.

- I know.

I keep scratching these scratch-and-sniff pizza stickers, but (sniffs) there's no cheese and pepperoni smells to sniff.

- And I can't sniff a whiff of my fresh desk.

I'd say I smell a word mystery, but I can't smell a thing.

(ringer chiming) - Scientist Cosmo's calling, so it probably is a word mystery.

- Word Detectives, something's wrong.

Someone swiped my smell machine, this one.

- [Sly] What does your smell machine say stench and aroma?

- I'm doing a smell experiment.

Those words are for different smells.

- You're right.

The dictionary says a stench is a gross smell, but an aroma is a scent or an odor that smells nice.

- Like a lemony fresh desk in the morning.

- That's specific.

- Wait, if these words are gone, is that why I couldn't smell my pizza stickers?

- It must be, and why I couldn't smell my newly cleaned desk.

- And why I can't smell the salmon sandwich I forgot to eat last week.

- Ew.

- Wow, we've never had two words go missing at the same time.

- Scientist Cosmo, tell us what happened and Sly will animate it.

- [Sly] Recap time.

- Vet Wilder and Reporter Read were helping me with my smell experiment, and I sprayed different odors to see how they reacted.

(mist whooshing) If they like it, they say, "Aroma."

(mist whooshing) If they didn't, they'd say, "Stench."

But when I sprayed the scent of peaches, Vet Wilder said, "Stench," and started sniffling in a handkerchief.

And Reporter Read did not like the smell of freshly cut grass.

She called it a stench and said, "Nothing to see here."

I went to get my clipboard so I can ask them about their reactions.

But when I got back, they were both gone, and so is my machine.

Now no one can smell anything.

- I love a sweet scent, but I can't say I'll miss the stinky stench of rotten eggs.

- All smells are important.

Aromas can reminds us of happy memories and stenches can alert us to risks, like if food has gone bad and can make us sick.

Not being able to smell is a big problem.

- So big, we should take a look at the scene of the mystery.

- Here, let me show you.

- I'm taking a screenshot for our case notes.

(camera shutter clicking) You good to go, Gabby?

- Sure am, Sly.

Scientist Cosmo, we'll sniff out the scent stealer.

- Please do.

Bye.

- Opening up our case notes.

We know the what and the where.

- [Gabby] Someone took the aroma and scent machine from the science lab.

- Now no one can smell anything.

- And it happened when Scientist Cosmo left to get his clipboard.

Our suspects are Reporter Read and Vet Wilder.

Now to find out who did it, how, and why.

- [Sly] Vet Wilder was sniffling in a handkerchief, and I'm guessing that's Reporter Read's notepad.

- Reporter Read had a weird reaction to the odor of cut grass.

- But Vet Wilder not liking the aroma of peaches is pretty suspicious.

- You're right.

How can you not like the smell of peaches?

- Let's call him and find out.

(ringer chiming) - Word Detectives, can't talk long.

I'm in the middle of something.

- Uh, what happened?

- Are you okay?

- It's weird.

Sully the Skunk escaped his habitat and sprayed the whole clinic with his stinky scent.

- Is that the weird part?

- No.

Usually, I have to wear one of these to wash the stench off the animals, but turns out I can't smell a thing.

- It's happening all over town.

- You helped Scientist Cosmo with his smell experiment today, correct?

- Yes.

Every spray had an awesome aroma until, ugh, the stench of peaches.

- But peaches smell delicious.

- Oh, yeah?

Tell that to my allergy.

I'm allergic to stone fruit.

- Still not helping.

- Any fruit with a pit, like peaches, nectarines, or cherries.

If I even smell a stone fruit, my nose runs so fast I can't catch it.

Wait, my handkerchief is missing.

- It's at the scene of the swiped scent.

- That's the science lab.

- I must've dropped it there when I left.

(water splashing) (puppy barking) (sighs) Gotta go.

My dog's just splashing around like it's a puppy waterpark.

Okay, bye.

- Hmm, if Vet Wilder took the smell machine, then no more peach odor and no more runny nose.

Two reasons to put Vet Wilder at the top of our suspect list.

- At least until we talk to Reporter Read.

(ringer chiming) - Hey, Reporter Read, what are you sniffing around for?

- Word Detectives, I wanna write an article about how much better fake grass is than real grass, but- - You can't find your notepad.

You left it at the science lab.

- And I love the aroma of real grass.

It reminds me of summertime.

- Oh, I think you mean stench.

And fake grass means no grass to cut, and no slippery grass for me to slip on, and, um, never mind.

I don't even wanna think about it.

I gotta go.

- She left in a real hurry.

Did she seem embarrassed?

- For sure.

Maybe reviewing our case notes will help us figure out why.

- [Gabby] Vet Wilder thinks peaches stink because of his allergy.

- [Sly] And Reporter Read thinks freshly cut grass has a stench.

- And she was acting embarrassed.

But why?

- Scientist Cosmo said smells can remind us of happy memories.

- But can they remind us of bad memories, too?

- I smell a break in the case.

Not really.

I can't smell anything.

But this is good, right?

- Yup.

Time to show everybody how and why the scents went bye-bye.

(ringer chiming) - Now presenting the word mystery animated reenactment of "Case of the Swiped Scents."

"Is this an aroma or a stench?"

- [Gabby] "Ew, peaches."

- [Sly] "Interesting.

How about this odor?"

(mist whooshing) - [Gabby] "Ew, freshly cut grass?

I do not like this embarrassing stench."

- [Sly] "Fascinating.

I'll get my clipboard."

- [Gabby] "If I take away all aromas and stenches, I'll never have to remember what freshly cut grass reminds me of."

(Sly imitates nose blowing) - [Sly] "All my smells are gone.

This stinks!"

- That last part didn't happen.

- But the rest did.

Reporter Read is who took the smell machine.

- I knew it wasn't me.

(Scientist Cosmo gasps) - She did it when Scientist Cosmo left to get his clipboard and Vet Wilder was sneezing.

That's how.

- Why?

Because the odor of freshly cut grass reminds her of something embarrassing.

- He's right.

A few years ago, I was doing a press conference for the whole town.

As I walked to the stage, I slipped on freshly cut grass.

I stood up, then slipped again, then again.

I got grass stains all over my clothes.

I took the smell machine so no one has to remember that kind of memory again, especially me.

- If that happened to me, I would think freshly cut grass was a stinky stench, too.

- Me, too.

I'm sorry, Reporter Read, but aromas and stenches can remind us of good times and the bad.

- I guess I do kinda miss the smell of my favorite note-taking pencil.

- I do miss the smell of my pets.

- Like I miss my pizza stickers.

- And I miss my lemony fresh desk.

- That's very specific.

I'm sorry, Scientist Cosmo.

I'll return your machine right away.

(ringer chiming) - Thanks, Word Detectives.

Now that aromas and stenches are back, I can continue with my smell experiments.

- I think I'll skip this one.

- (sniffing) Ew, what is that stench?

- A week-old salmon sandwich?

- Where did I put that?

- Ooh.

(Vet Wilder shudders) - [Wilder, Cosmo, and Read] Thanks, Word Detectives.

(notification chirps) - Ah, the sweet smell of victory.

(cleaner spritzing) (Gabby sniffing) (sighs) Lemony fresh desk.

- Pizza.

(Gabby laughs) (light upbeat music) ♪ It's "Wordsville" ♪ - [All] Wow!
