- 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- - [Both] Word mysteries!

- Together, we run the Wordsville Online Detective Agency.

- We'll find your missing word fast.

- Not to mention briskly.

- And swiftly.

- Yeah, we're really good with words.

- [Children] Wordsville!

- So you haven't said anything about the recipe I sent you.

How is it?

- It's soup.

I said thank you when you sent it, didn't I?

- Still nice to hear if you liked it.

- You used my book as a coaster?!

But I thought you were grateful I lent it to you?

- I was grateful, but now I'm not.

- So we're both feeling ungrateful?

Which is weird.

Could this be a- - Word mystery?

Singer Melody's calling.

- Word Detectives, it's terrible!

- What?

- What?

- I have no fan mail and I'm missing a thank you card with the word gratitude on the front.

I liked it so much I took a photo.

See?

But now [sobs].

- The dictionary says gratitude is the feeling that you wanna thank someone because of something kind that they've done.

- So without gratitude, no one feels like saying thank you.

- This is a word mystery, all right!

Singer Melody, tell us what happened and I'll animate it.

Recap time!

- [Singer Melody] Well, I was super busy writing this song for my amazing fans when Artist Clay came in with a portrait of me.

He also offered to fix the purple paint on my wall.

It was peeling.

Then Athlete Glory came in.

She wanted to show me a trophy she had won with the basketballs I donated to the gym and some exercises she had worked on for me.

But I was super busy writing a song, so I asked them to wait.

Before I could talk to them, they left and my gratitude card was gone too.

- Interesting.

Can you show us the scene of the mystery?

- [Singer Melody] This is where I last saw my card.

- [Sly] I'll take a screenshot for our case notes.

Don't worry Singer Melody, we'll solve this.

- Be quick about it, will you?

I need my fan mail!

- She could have said thank you.

- Actually, she couldn't because someone took her gratitude card.

- [Sly] Oh right, that's what happened.

Now we all feeling ungrateful!

- Her recording studio is where it happened, and the card was taken when Artist Clay and Athlete Glory came over.

They're our suspects.

Now to investigate who did it, how and why.

Let's go over clues from the scene of the mystery.

- There's a Singer Melody portrait with a trophy sticking right through it.

It's hard to miss.

- Singer Melody said Artist Clay brought her a portrait.

Let's start with him.

- Hey, Word Detectives.

- Hello.

What happened when you visited Singer Melody today?

- I wanted to give her a portrait I had made of her.

It was my way of saying thank you for her music, which inspires me.

- Did she love it?

- I still don't know.

As I waited for her to look at it, I repainted the peeling purple paint on her wall.

- That was nice of you.

- It was.

Athlete Glory came by to see her too.

But Singer Melody was super busy, so she never even looked up.

Athlete Glory and I gave up waiting, put our things down on a table and left together.

- Hmm.

What are you painting now?

- Nothing.

- Huh?

It's very dark.

Well, bye!

- Leaving without thanking me for my time?

So ungrateful.

- Oh, okay.

Artist Clay did something nice by repainting Singer Melody's wall.

- Would he then do something not nice, like take her gratitude card?

- I'm not sure.

Let's hear what Athlete Glory has to say.

- Oh, hi Word Detectives.

- Are you shooting the basketball Singer Melody donated to your gym into the trash?

- I think it's pretty obvious that's exactly what I'm doing.

I was grateful to her, but not anymore.

Not since I visited her.

- What happened?

- I went there to thank her for the new basketballs and showed her the trophy we won with them, but Singer Melody never looked at me, not even to see the new cardio exercises I came up with to help with her high energy performances.

She said she was super busy.

- Did that make you super sad?

Sad enough to take her gratitude card?

- No.

I put the trophy on the table so she could see it later, said goodbye to Artist Clay and left.

- Well, don't worry Athlete Glory.

We'll solve this word mystery for all the people in Wordsville!

- Whatever.

- No one seems grateful for our hard work trying to solve this word mystery!

- I feel you partner, but we don't solve word mysteries for the thank yous.

- I know.

It's what we do.

Let's go over our case notes.

Artist Clay painted Singer Melody's portrait and repainted her purple wall for her.

- And Athlete Glory came up with exercises for her and brought a trophy for her to see.

- [Sly] But Singer Melody was super busy and kept both suspects waiting so long they left.

Athlete Glory said she put down her trophy and said goodbye to Artist Clay, but he said they left together.

That's strange.

Wait, the portrait is on top of the trophy, which means- - It was put down after the trophy.

Not at the same time!

- And there are purple thumbprints on it.

You thinking what I'm thinking?

- I sure am Sly, I sure am.

- Now presenting the word mystery animated reenactment of The Case of Gone Gratitude.

Hi Singer Melody.

Look, I painted your portrait to say thank you for the way your music inspires me.

- Just a minute.

I'm super busy writing a song.

- I'll just repaint this purple wall while I wait.

- Singer Melody, I'm so grateful for those new basketballs you donated.

Look what they helped us win.

Just a minute.

Still super busy.

Okay, I also came up with some new exercises for you, but I'll wait till you're finished.

She's still too busy?

Oh, I guess I'll just go.

- Somebody needs a lesson in gratitude.

- Did you say something?

Super busy over here!

- Artist Clay is who did it!

- [gasps] Artist Clay?!

- How could you do this to me?

- He grabbed the gratitude card after Athlete Glory left.

That's how.

- It's true.

Singer Melody didn't bother to look at my portrait or Athlete Glory's trophy.

She wasn't acting grateful.

And that hurt.

- I understand.

I felt hurt too.

- I wanted Singer Melody to know how that feels, which is why I took the card.

But I did something not nice when I really just wanted to do something nice.

I'm sorry.

- I'm sorry too.

I was grateful, but I was so busy writing a song for my amazing fans that I guess I forgot to say it.

But that gives me an idea for a song I'll sing for you all when gratitude's returned.

- I'll bring the card back right away and fix your portrait.

♪ Thank you for all that you do ♪ ♪ Yeah I'm so, so grateful I've got you ♪ ♪ Yeah you - Yes!

- Yeah!

- That was amazing.

- I feel the same way.

I better get those basketballs out of the trash.

- And thank you Word Detectives.

- Thanks Word Detectives!

- And I just wanna say thanks for lending me your book.

It's great.

- And thank you for the delicious soup recipe.

You know what, I'm really grateful for?

- What?

- You.

- Me too, partner.
