- 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 for Online Detective Agency.

- We'll find your missing word fast.

- Not to mention briskly.

- And swiftly.

- Yeah, we're really good with words.

Wordsville!

- Wordsville!

Ready Sly?

Let's get serious.

We have to study some vocabulary words if we're going to pass our word detective test, so... - Gabby, I think you're frozen.

- Boo!

[dramatic music] - Hey, very funny.

- What is going on?

I can't be serious.

- Me either.

- If we don't get serious, we won't pass our test or get to keep the Wordsville detectives [cawing].

- Something's up, like a word mystery.

Hey look, Reporter Read's calling.

- Breaking news, I'm on the moon.

Not really, but I do need help.

My notebook is missing, this one.

- That notebook says "Serious".

- I keep notes in there on all my serious news reports.

- Serious means something that is important and not to be joked about.

Since the word serious is missing, we're acting the opposite, silly, ridiculous, and absurd.

- And all of this happened when I was working on a very serious and really meaningful news report.

[playful music] [Sly and Gabby laugh] - It's gonna be hard to take this case and our word detective test seriously, but we have to try.

- Tell us what happened and I'll show it to us with animation, recap time.

- I was at the newsroom working when both Baker Graham and Artist Clay came to visit.

I can't remember why they stopped by.

I was too busy writing my serious news report to pay attention.

But after Artist Clay and Baker Graham left, I started acting so silly that instead of writing my report with words, I used emojis and stickers.

Then I saw my notebook was missing, so I called you two.

- I smell a word mystery.

- I just smelled the sock.

Reporter Read, can you show us the scene as a mystery?

- Sure.

[dramatic music] That's where I usually keep my notebook, but I have no idea how these got there.

- I'll take a screenshot for our case.

Gabby, ready?

- We'll find who did the deed with speed for the Read.

- Time to get back to our cases old skippers.

We know what happened.

Someone took Reporter Read's serious notebook, and everyone is acting wacky.

- That's pretty good, but you should give us all mustaches.

Nevermind, I'm focusing.

Where it happened is the newsroom, and it happened when reporter Read was working on her news report [quacking].

- [Sly] Our suspects are Alice of Wonderland and Frankenstein.

- Sly, we have to fight the sillies.

- You're right, our suspects are Baker Graham, and Artist Clay.

Now we need to figure out who did it, how, and why?

Let's look at the scene of the mystery.

- [Gaby] There's a plate of smiley face cookies and some paint.

- Cookies are Baker Graham's department.

[phone ringing] - Word Detectives, I'm making gingerbread versions of everyone in Wordsville.

Oh, here's your word Detective Sly, "I solve word mysteries."

- Sly, you look scrumptious.

- The magic of frosting.

It always puts a smile on my face, see?

- I do see.

- Baker Graham, could you tell us why you were at the newsroom this morning?

- Well, I wanted to say hi and drop off some smiley face cookies for Reporter Read.

She always worked so hard reporting on serious news topics.

That's probably why she's always so serious.

I thought she could use a break with something that would make her smile, and now I'm going to make me smile.

- Hey, that's my head.

- When I realized she was too busy with her big news report, I left the cookies and came back here.

Maybe Artist Clay knows more, talk later.

- Baker Grandma's worried Reporter Read is a little too no nonsense.

- Hey, how could you not like nonsense?

- Let's see if Artist Clay has anything to say.

[phone ringing] - Artist Clay.

- You look different today.

- Oh no, Gabby, he's trapped in an invisible box.

- [chuckling] It's just a pretend box.

- Oh, I knew that.

- I thought instead of making art, why not become the art?

- Speaking of art, we saw something splattered in the newsroom.

- It's mine, I asked Reporter Read to model for my portrait of a serious person.

She's perfect for it since she rarely jokes around.

- That's true.

- But when I opened my paint, she asked me to stop making noise.

So I grabbed a cookie, cleaned up my paint and left.

Now I should go.

[bell dings] [playful music] - What did we learn today, Sly?

- This cat loves playing the piano.

[Sly and Gabby laughing] - Okay, so Sly, case notes.

- Right, Baker Graham brought the smiley cookies to make Reporter Read smile.

- This baby makes me smile.

[Sly and Gabby laughing] Oh, we have to stop.

What else?

- Artist Clay wanted to paint a portrait of a serious person.

- That's right, he wanted Reporter Read to be serious, but I know who didn't.

- Me too!

Let's show everyone how it happened.

[phone ringing] [vocalizing] Now presenting your word mystery animated reenactment of, "The Case of the Sillies".

- Reporter Read, I'm trying to capture the essence of serious, and you are perfect.

Just sit right there and I'll paint you.

- Click clack, I'm trying to type, I can't focus with all that noise.

- Hmm, I guess I should just go.

Oops, I ripped my pants.

- Hey, that never happened.

[Sly chuckling] - Reporter Read, I baked you cookies.

I hope they make you smile.

She's so serious about writing.

She didn't even notice the cookies, but I know what to do about that.

[suspenseful music] - Baker Graham is who did it!

[all gasping] - He swiped the notebook while Reporter Read and Artist Clay were busy, that's how he did it.

- He wanted Reporter Read to stop acting so serious all the time.

- That's why he took it.

- Yes, I did it.

Reporter Read, you were so serious about your big news report.

I thought you might want to take a break and have some fun, but I'm sorry for taking your notebook.

I'll bring it right back.

Or will I?

No, I'm just joking, I will.

[phone ringing] - Now that Wordsville is no longer silly, my serious news report is coming out.

It's all about Baker Graham and how hard he works to bake treats for all of Wordsville, that takes serious effort.

- It's about me?

Aw, thanks, I shouldn't have made decisions on how you should act or feel.

I'll take other people's feelings more seriously from now on.

- I'm ready to paint my serious portrait if you are a Reporter Read.

- Why don't we all share smiley face cookies first?

- I seriously love that idea.

- Thanks Word Detectives.

- Thanks Word Detectives.

- We did it, we solved "The Case of the Sillies".

Now we can get back to studying for our Word Detectives test.

- I guess the fun's over now, but here, I made us a practice test.

[mouse clicking] [dramatic music] Gotcha!

[Gaby and Sly laughing] Now, let's get serious.
