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!
