We arrived at Cat Galaxy, only to see a familiar face — Ed!

We also met Wolf's sidekicks, Cordy and Lem. They mocked us, then went off to take all of the station's stardust for themselves!

They really scared me with that...but luckily, we had a plan! The three of us restored the galaxy's stars like usual...

...And I messed with their spaceship! Just enough so they had to power the spaceship repair with all the stardust they stole!

They were so angry when they found out. Hopefully that'll keep them off our track for a while.

...But it seems like this next galaxy has a whole new problem waiting for us.

So the rumors about your group were true. Well, your time is up.

Are you another one of Wolf's sidekicks? Don't try and stop us.

Sidekick...? No, I'm Emilio! I'm one of the best star-makers in Bakery Galaxy!

And I am politely asking you and your friends to please stop what you're doing — resetting the bots and all.

Huh? If you don't work with Wolf, why do you care? Are you just a fan of his?

What? No! I don't like Wolf at all, actually. The design of his stars is so...stale.

But that doesn't matter — what you're doing is against the rules! The star-makers in charge have been discussing how to deal with Wolf...

So they told everyone to stay put until they make a decision. But here you are, doing whatever you want!

Um...but it might be a while before they decide what to do. I think it's okay for us to try new things...otherwise, won't Wolf just take over everything?

She's right. Doing nothing is exactly what Wolf wants us to do.

Well...I can see your point...but! You can't just show up to someone else's kitchen and act like you know better!

I'd like to see you try and make a new star for our galaxy...you'll see it's not so easy!

Oh, you're on. If we make an awesome new star, will you admit you're wrong?

Uh, I...I mean, yes, of course! But if you try and give up, you three have to admit you're wrong!

We've gotten involved with another interesting person...

But let's do it. We've done hard things before, and we can do it again.

Well! If you insist on doing this, then I'll be nice enough to watch over you. After all, I can't have you causing any more trouble.

Get ready, everyone. Star Transformer, make me a star!

Okay, let's see you try this one!! Can you make it all the way to the Starpad?

Woah, is that a new kind of bot?

I wonder how it works...looks like it's powering that tall button somehow!

...Hey, Emilio. You look like you really want to say something.

Oh, it's just...that bot is called a Laser bot. And the tall button is called a target. 

N-not that I want to help, or anything!!

Right...anyways, let's try coding the laser bot. I'll add the "turn" command...

Then I need to choose a direction. I'll pick "clockwise" for now, and we can test it out.

I see a problem with your code...but do you?

Hmm. Maybe I should have turned counter clockwise instead.

That might not be the problem. Is it just that the bridge turned off too early?

The laser also hasn't powered target D yet...is that the main problem, Emilio?

Well if you can't figure it out, I suppose I could tell you! It's—

Oh, don't worry! We can figure this out ourselves. Just give us a few minutes.

You're right, Valeria. The main problem is the bridge turning off too early — if we're stuck here, we can't do anything.

If I make the laser turn the other way, the bridge still turns off — so that's not the problem.

And like Jazmin suggested, I do think we need to hit target D eventually since it's connected to that launcher...

But it's on the other side of the puzzle, so that'll come later. First we need to figure out how to cross the bridge.

Hmph, I guess you all figured it out. But let me ask you this! Do you know what a bug is?

Oh, I love bugs! Ladybugs are my favorite...

Er, not that kind of bug. In coding, a bug means a mistake or error in your solution.

Finding and fixing those errors is called debugging! 

Oh, I remember reading about debugging in the bot manual! I it also listed 4 steps that can help you debug...

Yes! I follow those 4 steps all the time when I make mistakes while baking bread. It goes like this...

Step 1: understand the problem! 

When I see something go wrong, I ask myself: What happened? Why is that a problem?

You all answered those questions just now, talking about the bug in Luz's code.

I see. If we understand what the bug is first, we can take steps to fix it more easily. So what comes next?

I'm glad you asked! Step 2: plan a solution! Now it's time to think of ideas to fix the bug!

After figuring out what went wrong, I ask myself: What do I want to happen instead? How can I do that?

Hm...so, what do we want to happen instead of the bridge turning off?

I want the bridge to stay on until I'm done crossing it. Since target C powers the bridge, I want the laser to stay where it is.

And how can we do that?

Well...if a bot's doing something too fast, we usually need a "wait for" before that line of code.

Oh yeah! Looks like laser bots can wait too. Let me add it to the code.

I'll make it wait for switch E, since it's the only thing I can interact with after crossing the bridge. 

You have your plan, so it's time for step 3: try the solution! Run the code and see what happens.

Our plan worked! The laser is waiting, so I have time to cross. And if I flip switch E...

It turns!

You just did step 4: reflect on your solution! If your plan worked, you can move on. If not, go back to step 1.

Cool. Let's keep coding the laser bot — we want it turn around and hit target D, right?

Yeah. If I stand on the launcher when target D powers it on, I'll get launched over to the top platform...

And once you're there, you can move the cube to the cube tray. That'll turn on the bridge to the Starpad!

Right. So to make the laser hit target D, I'll add another turn...does it matter which direction?

Since the first turn is clockwise, this one should also be clockwise! Otherwise it'll turn back to target C.

That makes sense. Let me run the code again.

I just need to make sure I'm standing on the launcher when I hit the switch. Now—

Wah! Yep, that worked.

Now I just need to move the cube...wait, huh?

Heh. Seems like you ran into another bug! I told you this would be difficult!

Well since you so helpfully taught us how to debug, I think we got this.

...Oops.

Hehe...let's start by understanding the problem. First, what happened?

Target D powers both the launcher and the elevator. So I got launched over here, but the elevator and the cube went up.

And why is that a problem?

Now I can't reach the cube. So I can't turn on the cube tray.

Now to plan a solution: What do we want to happen instead? How can we do that?

We want to elevator to come back down so I can get the cube. As for how to do that...I'll have to think.

There's no way to stop the elevator from going up without using the launcher, so "wait for" won't help here.

But we can make the elevator come back down — we just need the laser bot to turn away from target D.

Oh...right! After Luz uses the launcher to reach the top, we don't need target D to be on anymore.

Yep. I'll add it to the code. A turn in either direction works, since we just need it to face away from the target.

Now to try the solution!

The plan worked! After powering the launcher, the laser turned away — now the elevator's back down.

Now I just move the cube to the cube tray...

...and cross over to the Starpad!

Woah, you did it!

Hey, don't forget our deal. If we make a cool new star, you'll admit you're wrong for trying to stop us.

I, I didn't forget!! I just thought...our bet would be no fun if you gave up right away! So I gave you some tips!

Anyways...let's just see if you can do the next one!

(He's totally trying to hide how much fun he's having...maybe this is the first time he's tried something new in a while.)

(If we can just sway him to our side, he might be really helpful...)

Alright, let's keep going! If we run into problems, we can just debug them.

You did it...you made a new star...!
