- You can't catch me! - Slow down!
Hey, boys, be careful there.
You need to be paying attention to the street.
Don’t worry, SchoolB! Catch me, Doug!
I'll get you!
Watch out!
Hello, Cleany. Why are you in such a hurry?
Poli, I'm late to clean up Orange St.
Alright. Be careful, okay?
- You okay, Whooper? - I'm okay, Poli.
You should remember to be extra careful
- when turning the corner. - I will.
I have to be going now!
Knocked over again!
Who keep's doing this? What a pain.
- Hello, Cleany! - Hello, SchoolB.
Whoa! What happened here?
Somebody keeps knocking down this trash can
- and making messes. - What? Trash cans?
This is the third time today.
Goodness. I wonder who could be doing this.
- Could you please move? - Oh, I'm sorry!
- Uh, good luck, Cleany! - Good-bye.
There we go.
No! Oh, not again!
This has to stop.
Rescue team, this is Jin. Oh, no, Cleany.
What? The trash can?
Yes. It's happened four times, so far.
Don’t worry, Cleany. We'll check it out right away.
What’s going on, Jin?
Oh, well, Cleany just called in to report that
somebody keeps knocking down one of the trash cans on Orange St.
Knocking down trash cans? That's not very nice.
But who would do such a thing?
We shoud go check out the scene.
- Roy, let's go. - Okay, Poli.
Uh, hey there, boys. Wait up!
- Ha? - Boys, listen
Could you do me a big favor and behave yourselves today?
And please can you be extra careful
when you're playing around trash cans. Understand?
- Yeah, whatever. - Yeah, whatever.
- Well. See you tomorrow. - Bye!
- You're it! - Oh, no, you don't!
- Look there. - What's this, Poli?
Of course. Roy,
I think I know who's knocking the trash cans down.
That's great, Poli.
Kevin and Doug!
No Whooper! Look out!
There.
- Here we go. - I'm so sorry.
Whooper, I'm glad you're sorry,
but have you forgotten that when a big vehicle like you
turns the corner, the rear wheels rotate inward?
What? What do you mean "inward"?
Kevin, Doug, I think you should know this too.
Sure!
When cars go around the corner,
the rear wheels always rotate
farther inwards than the front wheels.
The bigger the car is,
the more inward the rear wheels need to turn.
This is why it is very dangerous
to play around at intersections.
- Oh. Okay. - Oh. Okay.
And at smaller intersections, it's even harder to avoid cars.
So, you need to be extra careful.
Also, when you ride bicycles,
you should avoid turning the corners with other cars,
and you should keep a good distance from trucks
since your clothes or bags can actually get snagged.
So always stay back.
- Got it? - - Yeah, we got it Poli!
I understand. I promise, I'll be careful from now on, Poli.
You know, that means that this isn't a good place
- for this trash can. - That’s right!
It was you boys doing this?
Cleany!
Cleany! It's not how it looks…
You are very bad boys! Very bad!
Wait, no! It wasn't us!
Yeah! We're innocent!
