>> Until everyone sees what we saw, it's going to be hard to convince them to conserve water.

>> I've been trying to tell them if they'd just make a few small changes, they won't be wasting so much water.

>> Like stopping this leak?

>> Yes.

It just started last night.

My dad promised to fix it.

>> It's just leaking a little.

>> A little, yeah, but these tiny drips can add up to a lot.

I'll show you.

We'll measure.

>> One scale for measuring.

>> That won't work, Digit.

You measure a liquid by how much space it takes up, so you need some kind of container, like this glass, but let's start with an empty one.

>> It's going to take a while to fill that.

♪♪ >> Whoa.

That didn't take long at all.

>> Ten minutes to be exact.

>> One glass is filled in 10 minutes, so two glasses in 20 minutes, three glasses in 30 minutes.

>> That's three full glasses of water every 1/2 hour.

>> Yoikes!

That's a lot of glasses of water.

Imagine how many you'd have in a full day.

>> See what I mean?

>> Wow, what a waste.

>> I asked for a town meeting to explain what everyone needs to do.

Hopefully they'll listen this time.

>> They're gone.

>> My plan is working.

>> What plan, Boss?

>> We've just been waiting here for weeks doing nothing.

>> That was the plan.

While we've been relaxing, that little girl has made a time machine.

>> Oh, brilliant, Boss.

>> Just brilliant.

>> And now that that supercilious cybird has brought the missing part, just as I knew he would, we can use the time machine ourselves.

>> Can we go back in time to when you had hair?

>> What did you just say?

>> He said, "Can we go back in time" -- >> I heard what he said!

Listen closely.

Once we get that time machine, we're going back into the past when I worked for Motherboard, only this time, I will reset the course of cyber history.

This time, I will be in charge of Cyberspace, me, the Hacker, not Motherboard.

[ Laughs wickedly ] Now, let's find a way to get that time machine to the Wreaker.

♪♪ >> Why are we here?

What's this all about?

>> Everyone, everyone, please.

For the past few months, I have been telling you that the water levels here in Canalia are going down.

>> There's nothing to worry about.

We get plenty of rain.

Besides, Canalia is made of water.

>> Yeah.

>> Mm-hmm.

>> Who is that guy?

>> It's okay.

I know it's hard to see the difference, but if we don't make some changes now, we might just run out of water.

>> What?

>> You got their attention now.

>> If everyone in Canalia could save just one gallon of water every day... >> One gallon is nothing.

>> Yeah.

>> That's my point.

It may not sound like a lot, but there are 365 days in the year, so if we each saved just one gallon a day, we could each save 365 gallons a year.

[ Crowd murmuring ] >> With everyone working together, the amount of water you could save will add up fast.

>> Calm down, everyone.

We don't have to worry.

We're surrounded by plenty of water.

>> Sounds good.

>> It's that guy again.

>> Dad.

>> That's your dad?

>> Honey, you have to stop worrying about all this water stuff.

>> But, Dad, you have to listen to me.

>> What?

>> You're losing them.

>> We have to do something.

>> Please, everyone listen.

Pearl is telling the truth.

You have to believe her.

>> Why should we?

Does she have proof?

>> She does.

>> What proof?

>> She built a time machine.

>> Matt!

>> she did, and she can show you how Canalia has changed over the years.

>> A time machine?

♪♪ >> Thank you all for coming.

Don't worry.

Everyone will have their chance to see what I'm talking about.

♪♪ May I present my time machine?

[ Gasping ] >> This is your time machine?

>> No.

It's not.

I mean, I don't know what this is.

>> Wow.

>> Waste of time.

>> It was here.

We saw it.

>> We went back in time ourselves.

>> Pearl, honey, I know you think we need to conserve more water, but making up stories about a time machine is not going to help.

>> But, Dad... >> Wait!

She's not making it up.

>> I'm really sorry, Pearl.

Maybe I shouldn't have said anything.

>> It's not your fault, Matt.

I guess I did this all for nothing.

>> No way, Pearl.

We'll find your time machine.

>> And we'll find out who took it, too.

>> Now no one will ever believe me.

>> Pearl, come back.

>> I'll go.

You guys find the time machine.

>> Look at this.

Who would do such a mean thing?

>> Hey.

This stuff looks familiar.

[ Gasps ] Wig gel!

>> Hacker!

>> [ Gasps ] If Hacker has the time machine, there's no telling what he could use it for.

>> We've got to get it back for Pearl.

>> And for all of Cyberspace.

>> Faster!

I want to get this to the Wreaker.

Soon all of Cyberspace will be mine.

>> I'm going as fast as I can, Boss.

This thing is heavy.

>> [ Grumbling ] >> Why wait, Boss?

Let's take over Cyberspace now.

>> Yeah.

Let's do it now.

Then I can stop rowing.

>> You're right.

For once, you're right.

There's no need to wait.

Follow me.

Let's see.

How many years ago did I work for Motherboard, 5, 18, 22?

>> I think this many years.

[ Whirring, beeping ] >> No, wait!

>> Uh-oh.

>> Yikes!

Say, "Hello," to Motherboard.

>> Hello, Motherboard.

[ Chuckles ] Ah!

>> Too far back, right?

>> Let's go forward.

[ Whirring, beeping ] Yikes!

>> Hmm.

>> Ah!

>> My turn.

>> Enough!

Let's get this machine back to the present and figure out how it works.

>> The water is even lower than last week.

There are even some spots that are too shallow for the gondolas.

>> That could be dangerous.

>> It is, but no one believes me, not even my dad, especially now that he thinks I made up the time machine.

I wish Matt hadn't said anything.

>> He only wanted to help.

We all do.

We'll make them believe.

You'll see, and we'll get back your time machine, too.

♪♪ >> Hacker!

There he is!

>> And he's got the time machine.

>> Push, Didge, push.

>> I'm pushing.

>> Hey, Boss, can we get an ice cream?

>> Not now, you bucket head!

We're almost to the Wreaker.

Control of Cyberspace is finally within my grasp.
