My name is Agent Orla.

These are my partners, Oswald, Omar, and Osmerelda.

This is an optical illusion.

We travel the world investigating anything strange,

weird and especially odd.

Our job is to put things right again.

Who do we work for? We work for, Odd Squad.

Monumental Oddness.

Duh duh duh duh duh dun!

Duh duh duh duh dun-dah! Ba dadda duh dah dah!

Osmerelda, you've got to see this.

It's the newest issue of Shmumber travel magazine, and look!

It includes Omar's list of the top 25 world's

best monuments.

Two questions.

First, how did Omar only choose 25?

He narrowed it down from his original list

of two-thousand-five-hundred. Dark days.

Second question: where is Omar?

He's giving a speech at the 19th annual snow globe convention.

This magazine article is getting him a lot of attention.

Agents, you have an incoming call from the Little O.

There you four are... Wait, there's only three of you.

Where's Omar?

Giving a speech at a snow globe convention because he wrote

an article for a travel magazine. Oh, I know.

And so does a villain!

And that's why something very odd has happened.

Look.

I'm Stu Venir, brother of Sue Venir.

She's at her best friend Becky's wedding right now.

Didn't get an invite, but I did get Omar's list

of top 25 world monuments.

And I'm gonna turn all of 'em into tiny little key-chains.

Like this one.

The angel of independence from Mexico City.

Got it. Shrunk it!

It's mine now. Ha ha ha!

Bye!

-This is bad.

You're telling me.

According to Omar's magazine article, the monument was built

in 1910 to represent the beginning of Mexico's independence.

Also, Odd Squad helped build that monument to hold down a giant

pudding geyser.

Now that it's gone, things are a mess.

Whoa. And that's not all!

Stu turned another monument from Omar's list into a key-chain.

The Queen Victoria Memorial in London!

Not the Queen Victoria!

It was built in the 1920s to commemorate...

Oswald, I hate to interrupt, but I need one of you to clean

up that pudding geyser, while the other two of you figure

out where Stu Venir will strike next.

On it. Well, what are you waiting for?

Go!

How shall we proceed? I'll go to Mexico City!

I love pudding!

Woo!

Weeeee!

So, how do we catch Stu Venir?

We call Omar, tell him that it's an emergency,

and that he has to leave the snow globe convention.

I can't leave the snow globe convention

What? Why?

I'm giving a very important speech.

Look at me! I even wore a tie!

You wear a tie every day.

All the same, I'm confident you can solve the case without me.

We don't know world monuments like you know world monuments.

The souvenirs on my shelf will help you.

Maybe there's a pattern to the places

Stu Venir's striking.

Or maybe it's totally random, and life has no meaning.

Either way, I gotta go. Good luck!

I found Omar's souvenirs!

The places in these snow globes are the same two places

Stu Venir's struck so far.

So, what do these two monuments have in common?

They both have wings. Yeah, but...

no other monument on Omar's list has wings.

And Stu Venir said he would strike every single monument in his list.

So perhaps it just random and life is indeed void of meaning.

Orrr...

Maybe Stu is striking in a number pattern.

Omar's list of top 25 monuments are all numbered.

And the monuments he struck were number 2,

the Angel of Independence, and number 4,

the Queen Victoria Memorial. 2 is 3, 4...

2 numbers away from 4! Stu's skip-counting by 2.

So that means the next monument Stu will hit is 6!

2, 4, 6! And which monument is number 6?

The Merlion in Singapore.

You should dress warm today, it is very cold in Singapore.

What?

I thought it was warm in Singapore.

We all have days when we don't feel like ourselves,

cities included.

Ah, makes sense.

Stu Venir is not here yet.

Perfect.

It'll give us a chance to clear the area.

Attention humans! I think that covers everyone.

We need you to leave the Merlion! There's a villain coming.

Awww, awww.

It sounds as though they wish to finish taking their

tourist photos.

And I came all the way from Denver to get my face painted!

-And I'm not leaving without coins in my bucket!

Looks like we're gonna have to do this the hard way.

Thanks again, Odd Squad!

Oswald speaking, with his mouth! Where are the two of you?

We figured out Stu Venir's pattern and are waiting

for him at the Merlion in Singapore.

Stu Venir just struck the Empire State Building!

In New York City! The Empire State Building?

The one built in the 1930s, and made...

Yes!

You need to figure out Stu's pattern and stop him A.S.A.P!

We should head back to the van, put our brains together,

and see if we can crack Stu's pattern.

Take these. Hey, you should keep those.

You've got a future with the sticks.

Thank you!

What if Stu's pattern has nothing to do with numbers?

Maybe he's alternating between statues with faces and buildings

with windows...And

windows kinda look like faces if you think about it.

Halt that thought.

The first 2 monuments struck were number 2 and 4.

And the Empire State Building is number 8 on Omar's list.

It's not a skip counting pattern, it's a doubling pattern!

Because the double of 2 is 4, and the double of 4 is 8,

which means, the next monument that Stu will strike is the double

of 8!

I do not have enough fingers, but trust me on this one,

it is 16.

And monument number 16 on Omar's list is the Eiffel tower.

Let's go!

Arriving in Paris, the city of lights!

Fun fact, it only has one stop sign in the entire city,

and we just flew past it!

Everyone, there is a villain headed this way!

We need you to move the wedding away from here!

But we've been waiting for this day for years!

-And there's no villain stronger than our love for each other!

Aw! Could you get married fast?

We would, but our wedding officiant isn't here yet.

The same for our flower girl!

-And our musicians!

I can't walk down the aisle without music!

Shmumber's dictionary defines love as...

Oh, one moment.

Oswald's house of photography and wedding planning!

Where are you now?

Wrapping up a wedding at the Eiffel tower before

Stu Venir shows up.

While I respect you for making sure two people have memories that

will last a lifetime, Stu Venir just struck 2 other monuments!

What?

The Glass Hall in Denmark and Triton's Fountain in Malta!

Wait.

The same Glass Hall built in the 1940s and Triton's fountain

built in the 1950s?

Yes! You need to solve this!

Now. Good job, take care, bye!

Let us head back to the van.

Pardon!

Do you mind just finishing this before you go?

Right! I now declare you married!

Have a wonderful life, goodbye.

The numbers Stu Venir's striking don't fit in any kind of pattern.

Hang in there, young Oswald, we will figure this out...or

we will not and things will be bad.

I am covering all the options.

Oswald speaking, very grumpily.

How's the search for Stu Venir going?

Not good. We're stumped.

How's it going with the pudding geyser?

Also not good!

I haven't seen this much pudding in my entire 10 years!

Years! That's it!

Gotta go, bye!

Stu is striking monuments by the decade they were made in!

Decade?

A decade is a period of ten years, starting with the year in the tens

place. The Angel of Independence...

was built in 1910!

The beginning of a tens decade

So if the first monument he stole was made in the tens...

The next monument he took was the Queen Victoria Memorial,

which should've been completed in...

In the 1920s! And the Empire State Building...

The 1930s!

And the next to be stole were built in the 40s, and 50s!

Tis like counting by tens!

That means the next monument Stu Venir is headed to was built

in the 60s.

And there's only one monument on Omar's list built then.

The Seattle Space Needle.

Odd Squad, Odd Squad, stop right there!

Gah! How did you find me?

Tis all thanks to Omar and his knowledge

of world monuments. Aw, thanks Orla.

Also, show's over, Stu Venir.

I have to say, if your list wasn't so good, I wouldn't have bothered

making them into key-chains. Thank you!

And? And

I'll put them back where they belong.

Blah, blah, blah.

What shall we do to celebrate? Call Osmerelda.

I have an idea.

Party Crashers. Alright team, you ready?

Ready. Hats on.

Birthday hats are in position.

Osmerelda, give me an update on Oswald's cake.

Also ready. Woah!

Impressive. Thanks!

And I have toiled many a day preparing this small

but mighty birthday gift.

It is certain to make young Oswald cry tears of joy.

Cool.

This card only took me 5 minutes, but it was a quality 5.

Let us go and surprise Oswald.

Happy birthday Os... wald?

Lo, I command one of you Oswalds to this confusion we are feeling

in our brains and hearts.

Three creatures chased me, then caught me, then turned into me.

Thank you... One moment.

This is strange.

Must've been some kind of cloning creature.

Which means 3 of those Oswalds are actually creatures.

So, only 1 of them is the real Oswald?

But, which one? 1 It's me, right over here.

Me, not you. 2 It's me, right here.

No them, it's me. 3 It's me...

it's me. Not you.

4 It's me! It's me!

Always has been me!

I have an idea. We have 4 interrogation rooms.

Let us split up the Oswalds, and then we shall ask them

questions in order to figure out who the real Oswald is.

We do not have that kinda time. This cake is an ice cream cake.

If we spend all day running from room to room, it'll melt.

Could yo not just place it in the freezer?

I did not spend 17 hours on this cake for it to taste like freezer!

Good point.

I have an idea. There.

We're ready to go.

What is this computer box we find ourselves in?

It's a video chat program.

I use it to talk to Odd Squad friends all around the world!

In my day, we used to just tie a note to a rock.

And then send it to a friend?

No. My friends were mostly rocks.

I still don't see how this helps my melting cake situation.

Now we can ask all 4 Oswalds questions without running from

room to room.

Bringing up interrogation rooms 1, 2, 3, and 4.

Hey Oswalds, can you see us? Yeah, I can see you.

Let us begin.

You all claim to be Oswald, so prove your word is true

by answering this question.

What was your job before joining OSMU?

Library museum person. Lucky guess.

Only the real Oswald will know this.

Who is your favourite fictional character?

Detective Shmumbers! Double lucky guess!

Time for a question only my best bud Oswald can answer.

What is your favourite salty snack?

Pumpkin seeds lightly dusted with paprika

Okay, that is just weird.

How do you know all this? Because I'm the real Oswald.

Uh, sit tight Oswald 1, 2, 3 and 4.

We'll be right back. Okay.

Now what?

There you 3 are.

I have that creature info you asked for.

What info?

I maaay have told Little O about the case so she could help

us solve it so my ice cream cake won't melt.

The creatures you're dealing with are called party crashers.

They turn into kids on their birthday to steal their birthday

party fun!

I know! Clever and horrible.

What's worse is that they'll start cloning themselves.

So if you don't solve this case by the time this sand timer runs

out, there'll be a thousand Oswalds.

We do not have that much cake.

Little O, tell us all you know of these hideous creatures.

Sharing my screen.

According to the Odd Squad database, there are 3 different

party crashers: a yellow one, a red one and a green one.

When a yellow party crasher turns into a kid, it never gets the size

of the hands right.

Well that should help us figure out who the yellow one is.

In the meantime, I'll see what I can figure out about the other

two party crashers.

But first, some emojis should cheer you up!

Aw, so nice! Ooh!

Those produce joy.

So, whoever's hand is a different length is the yellow

party crasher. Bringing up Oswald 1.

Show us thy hand.

His hand is... ...6

inches long.

Bringing up Oswald 2.

Also 6 inches long.

Here's number 3.

Uh, Oswald 3, please hold up your hand.

3 Un-unh. No measurement, no party.

12 inches! You are not the real Oswald.

Yes! 1 down, 2 to go.

We must solve this with haste so I may present Oswald with

my small, but heartwarming gift. Also...

My cake is getting soft!

I've dug up some more info! Check this out.

The red party crasher can't stand the cold.

If it gets too cold, it'll turn back into a creature.

While you figure out who that one is,

I'll research the green creature. We're on it, Little O.

You better be!

We're running out of time!

So, we need to figure out which Oswald can't stand the cold.

Luckily, we can adjust the temperatures inside

the interrogation rooms.

Right now, the inside of the interrogation room is 70

degrees Fahrenheit, which feels like the inside of your house.

So, all we have to do is lower the temperature until

one of the Oswalds turns into a party crasher.

Exactly. Bringing up interrogation rooms.

Hey Oswalds, we're gonna cool off the rooms a little bit,

dropping temperature down to a chilly 50 degrees Fahrenheit,

which feels like a winter day.

1 Oh, that's chilly.

2 Really chilly. 4 I enjoy this.

This is comfortable. Oswald 4 seems happy.

He can't be the red party crasher. Unless he is faking it.

Drop the temperature.

Dropping down to a cold 40 degrees Fahrenheit.

4 Wow, the cold is so wonderful.

I do not find Oswald number 4's acting convincing.

Dropping down to 32 degrees Fahrenheit,

which is the temperature water freezes at.

4 Uh-oh.

Yes! This is great!

Only 2 Oswalds left. 1 Come on!

I'm the real Oswald! 2 No, I am!

I want my party! Uh, hang tight fellas.

We need to hurry.

The cake has gone from soft to mushy!

Why don't you just put the cake in the freezing

interrogation room?

I did not work 17 hours on this cake for it to taste like

interrogation room!

My research on the green party crasher is complete.

Do you want the good news, or the bad news?

Give us the bad news. This case is unsolvable!

Um... what's the good news?

Mostly just that I figured out the bad news.

Sharing screen.

The green party crasher is also known as the perfect

party crasher.

It can perfectly shift into another person with

no physical differences.

No different hands, no different body temperatures.

Even their organs are the same, which is both cool

and super creepy.

So we can never tell the two Oswalds apart?

Correct. Um, Omar, what are you doing?

Changing Oswald's birthday card.

It used to say There's only one special guy like you.

But now it says: There are only two special guys like you.

I would change that to a thousand special guys like you.

Prepare your umbrellas, for they will all shed tears of joy when

they see my heartwarming gift.

Wait one tiny little notch on the sundial!

I can use this gift to help us! Quick!

I need something to measure with!

How about... a ruler?

It needs to be something I can measure liquid with.

Ooh! How about these pint glasses?

Perfect.

Omar, place this in your computing device.

I shall be back.

I have no idea what she's doing, but I hope she does it fast!

Me too, because we've gone from mushy...

to oozy.

The measuring cups are in position.

Omar, please present my gift.

Happy birthday young Oswald!

1 That video was great. 2 So great.

Both Oswalds seem really touched. Yes, but which is more touched?

I shall tell you. Quickly!

Oswald 1, please hold up your cup.

This measuring cup shows Oswald 1 cried a half pint of tears.

Oswald 2, your turn.

Oswald 2 cried 1 pint of tears, which means Oswald 2 was more

moved by my heartwarming video, which means,

he is the real Oswald. 2 Thank you!

And that means Oswald 1 is the green party crasher!

1 Uh-oh.

Party crasher, why did you cry at the video?

Because your friendship is beautiful and moving to me.

Makes sense.

Looks like it's finally party time.

Hurry! My cake just crossed into soupy!

There's only one special guy... no wait, only two special guys...

no wait, one special guy like you.

Aw! Thanks everyone.

Happy birthday, Oswald. I hope you saved room for cake!

Awesome! I love my cake soupy!

Birthday boy gets the first swig!
