We traveled to the Garden Galaxy station,
where we met Jazmin! 

She's shy, but she really knows her stuff!
We learned all about sequencing thanks to her.

Hehe...thanks to you two, I worked up the courage to talk to the rest of my station. They'd been arguing over our stars...

After I talked to them, everyone agreed to make
all different kinds of garden stars!

With peace back in the station,
Jazmin joined us for the adventure...

But as we approached the next galaxy,
a claw tried to hit our ship! Where did we end up now?

Whew...just managed to dodge that, whatever it was...

That was one of our adorable cat stars! Welcome to the Cat Galaxy station!

Hold up, aren't you Ed? We just met at Fruit Galaxy...Why are you here now?

Hm? No, we've never met before! You might have met my twin though!

But yes, my name is Ed—

AHEM!

Um..h-hello?? Oh gosh, more new people...

Allow us to introduce ourselves! I'm Lem...

...and I'm Cordy!

And we'll take over every galaxy!

Uh...

That's right — tremble in fear! We're Wolf's most trusted followers,
on special orders to stop you!

So you're his sidekicks? We're not scared of you.

You seem confident. But let's see how confident you are
once we drain all the stardust from this station.

So you're here to steal from us, huh? That's just like Wolf...

You...! Say one more bad thing about Wolf — I dare you!

Relax, Lem. Let's head to their stardust reserve and start our mission.
What could they possibly do to stop us?

You're right, Cordy! We don't need to worry about these fools. Let's go!

W-what are we gonna do?!

Hm...if we restore the galaxy's stars like we usually do,
that would fix the stardust problem. Right?

It would help for a bit, but they could just steal that stardust as well.
We need a way to distract them or slow them down.

Um...could we just ask them to stop and give us the stardust back?

I don't think...actually, wait. That's a purr-fect idea!
While Cordy and Lem are busy draining our stardust...

I'll secretly disable parts of their spaceship! That way, they'll need
to use the stardust they took to power the station's spaceship repair!

I see...they won't be able to leave this galaxy otherwise.
Meanwhile, the three of us can solve puzzles to help restore the stardust.

Got it — we'll leave the spaceship to you, Ed. Luz and Jazmin, are you ready?

Ready! Star Transformer, make me a star!

Okay, here's our first puzzle. The Starpad is in the top right — we'll need to turn on this bridge to reach it.

Yeah, we're kinda trapped up here...
not much we can do other than code the bots.

Since we need to code two bots this time, figuring out the right sequence of steps is a little more complicated.

So let's start with the basics:
which of the two bots should move first?

The Walker?

Or the Grabber?

Actually, could both bots start moving at the same time?

I'm not sure yet. Let's try some things and see what happens.

Let's use the process of elimination to decide which bot should move first! What would happen if the Walker moved first?

If the Walker moved first, it could go to button A. That would help turn on the bridge to the Starpad.

That might be a good first move — the Walker can't go to any other spot right now.

I'll add that code and then see what happens.

...Hmm. The Walker turned on button A, but it made those two bridges collapse, too. Now the Grabber can't go anywhere.

Those are called drop bridges — they collapse after being crossed once, so let's be careful about when to use them.

In that case, let's not move the Walker first. We definitely need the Grabber to move around the puzzle too.

If both bots moved at the same time, the Walker would still cross the drop bridge before the Grabber. That wouldn't work.

So by the process of elimination, the Grabber must need to move first...but wouldn't the drop bridge still collapse?

Yes, but look! There's a regular bridge here that's connected to cube tray B. The Grabber can turn that on!

I get it. Unlike the Walker, we can code the Grabber to move the cube. That'll help the other bot cross.

So first, pick up the cube at position D...

...Then drop it at cube tray B. That should turn on the bridge for the Walker!

Great! Now that we've coded the Grabber's first steps, let's switch to coding the Walker!

Oh? Why not just keep coding the Grabber until it's done?

You could try that — but that might be a little tricky. In this puzzle, the bots need to help each other by taking turns.

I find it easier to code the bots by switching back and forth in the order that they need to move.

I see. The Grabber just had its turn to move, so now it's the Walker's turn — that's what we need to code next.

I'll switch back to the Walker. Maybe now it can go to button A? Let's try it out.

Whoops. The Walker crossed the drop bridge first again, so the Grabber fell.

Ah! Right. Since the bots need to take turns,
they also need to wait for each other.

They can do that?

Yep! Since bots can trigger events, like pressing a button, other bots can listen for those events using "wait for".

Makes sense. So what event can the Walker "wait for" to make sure the Grabber is done with its turn?

The Walker should wait for cube tray B, since that's what turns on the bridge — then it'll be safe to cross.

That's better. The Walker has nothing more to do in this puzzle, so let's switch back to coding the Grabber.

What should the Grabber's next line of code be? Let's think. 

Remember, the bots are taking turns. While the Walker finishes its turn, the Grabber has to wait before continuing.

Right, I'll add that as the next line of code.
But which object should the Grabber wait for?

Hmm...not cube tray B or C, since only the Grabber
can use those. A bot can't wait on itself. 

Since the Walker ends its turn by pressing button A, we can have the Grabber wait for A.

Now that the Grabber is waiting its turn, what should it do next?

The Grabber needs to move the cube to cube tray C. That'll turn on the bridge to the Starpad!

So it just needs to pick up at cube tray B...

...Then drop at cube tray C. That should be all we need — let's run the code to check.

It worked! Thanks to us, the bots learned great teamwork.

Yep, now they know how to "wait for" their turn!
Okay, on to the next—

Well well well, looks like your little team
restored one star! Big deal!

Uh huh...shouldn't you be helping your friend or something?

Oh please! Cordy can handle it on her own.
I'm here for some entertainment!

Psst, Valeria...I don't know why he's doing this, but isn't it good for us if they're separated? They'll work more slowly that way.

Oh! True...

Well Lem, we're headed to the next puzzle...not that
you could solve it. Better hurry up, or we'll leave you behind!

Oh yeah?? Bet I could solve the next one in my sleep,
unlike you three!

He took the bait so easily...

We just need to finish our part here, and Ed will do his.
We're counting on you, Ed!

Lem, I'm done draining all the stardust!
We're about to bring Wolf the biggest haul ever...!

Haha, he's gonna be so proud of us! Quick, let's head back to our...

...Our spaceship...

IT'S WRECKED?!

Teehee!

YOU...! I should've known you were up to something!!

Wait...not only that — you three restored all of the galaxy's stars??

Yep. We even made a new star!

It's a kitten star...isn't it sooooo cute?

How...when did you do that?!

Cordy, I sent you a message about it on our Talk-Its! Didn't you read it??

No, I didn't! I was a little busy because someone 
left me to do all the work by myself!

Sorry to break this up — but if you two want to leave this galaxy,
you'll have to use your stolen stardust to power the spaceship repair!

Ugh...! Fine! But we'll get you for this — just wait!!

Mission complete. Thanks again for your help, Ed.

Of course! Those two could learn something about
teamwork from us, don't you think?

Totally. How'd they know where to find us, anyway?

I think some people are taking notice of the recovering galaxies...
You might even have a small group of supporters!

But because of that, Wolf is only going to keep a
closer eye on you from here on out. So be careful.

You might not need to worry about those two for a while, though. Look.

We can't go back to Wolf empty-handed!
C'mon, let's follow them to the next galaxy!

No way. We have a duty to update him on the situation.
Let's go back to his station.

But...! Ugh, forget it. We might never leave this place
with how long the line for the repair is!

Seriously, why are so many of your spaceships broken?!

We work with cats...You know how it is.

...Coming here was a mistake.

Heh...I see. Well then, let's take this chance to head out.

Safe travels! Maybe I'll see you again sometime!

...I have a feeling we will. Bye for now!

Oh, we're here! I've heard a lot about this galaxy!

And I've heard a lot about you. Sorry, but your time is up.
