Get Ready!
Part 1
Last time on
Star Stuff!
We traveled to Underwater Galaxy, where Cordy and Lem were waiting to capture us!
LUZ
But we were saved by Valeria, who agreed to leave
with those two. In return, they'd leave us alone.
JAZMIN
I felt so confused...but Ed was there to help us out! He chased down Cordy and Lem while the rest of us restored stars.
LUZ
Seeing that you fixed up the galaxy, Cordy and Lem brought me back. But I felt like you all didn't need me anymore...
VALERIA
But you helped me see that's not true. I don't have to be perfect to be part of the team. Thanks everyone.
VALERIA
Of course. Cordy and Lem did end up capturing us
after all that...but at least we're together!
LUZ
Our story continues...
Hello, Wolf? This is Cordy. Good news — we caught the rebels.
CORDY
Excellent work!! Now go ahead and trap them in our Reflection Galaxy!
WOLF
Oh...you don't want us to bring them to you?
N-not that I'm questioning you, of course!
LEM
They're just a bunch of kids, right? I trust you two can handle
them without me. I'm very busy doing...other stuff!
WOLF
Right...of course. We'll need to refuel our ship at the station,
but we'll head over to you after that. Cordy and Lem, out.
CORDY
Great, great! Ooh, the ice sculpture of my face is here! Gotta go, byeee!

We're here. Everyone, follow me.
CORDY
You two really think you can trap us at a regular station?
VALERIA
It's not regular, it's controlled by Wolf! We have special mirror rooms here
that can trap you by confusing your senses...including your memories!
LEM
Yikes, that sounds bad. If those two end up leaving without us, we'll be stranded here — our spaceship's back at Underwater Galaxy.
LUZ (THINKING)
We can't give up, though. We're so close to bringing Wolf down, I can feel it...
LUZ (THINKING)
Everyone...try to stay calm. Wolf's underestimating us again.
Even if we're separated, I'm sure we'll all find a way out!
LUZ
A while later...
Ugh...where am I? What are all these mirrors around me...?
LUZ
I can't even see my own reflection clearly...who am I again?
LUZ
Ah, wait...my uniform. That's right, I'm Luz.
I'm a star-maker at Rainbow Galaxy.
LUZ
Star-making is boring, though. We just watch the bots do everything...
LUZ
No, no, that's not right. That's how it used to be,
but...things are different now. I'm different now.
LUZ
Because of Valeria, I learned how to use the old star-making technology. That's how we've been restoring stars, after Wolf took over everything.
LUZ
We learned how to code the bots from scratch.
It was a little scary at first, and we made a lot of mistakes...
LUZ
Like that time we learned the importance of coding the right sequence —
a set of steps in order.
LUZ

To do that, we looked at how all the puzzle pieces connected,
starting from the goal. Then we'd trace the path backwards from there.

Right...we've solved so many puzzles by now,
it's not scary anymore. And because of that...
LUZ
...I'm confident that I'll find a way out of here!
LUZ
Oh! My reflection's back to normal...and I can see the way out! Looks like I need to solve a couple puzzles to get there...no problem, I got this!
LUZ
Meanwhile, Jazmin...
Oof...I feel dizzy...
JAZMIN
That reflection...is that me? It's too cloudy to see...
JAZMIN
I guess I've always been hiding...scared to talk to others,
even though I really wanted to.
JAZMIN
Instead I'd always just read alone. Like...this bot manual...
JAZMIN
...Oh! That's right, I'm a star-maker at Garden Galaxy!
That's where I met Luz and Valeria...
JAZMIN
Thanks to them, I worked up the courage to talk to others...
I even got to try coding bots after reading about it so much!
JAZMIN
We solved lots of puzzles, including some where two bots needed to work together. It was confusing at first, seeing them move at the same time...
JAZMIN

A
So we figured out how to make the bots take turns instead! But...how did
we do that, again? I think there was a specific command we used...

Of course, we use wait for ! That way we can make one bot
pause and wait for a specific signal while the other bot moves around.

Meanwhile, Emilio...
Urgh, what's this mirror...? Why is there a crack in it?! So annoying...
EMILIO
What am I doing here anyway?? There must be some reason.
Guess I should just sit tight and wait for orders...
EMILIO
...Hm? What's this scroll? Problem-solving steps...?
EMILIO
...Wait! Why should I sit around? I can solve my own problems!
I'm a proud star-maker from Bakery Galaxy!!
EMILIO
That's where I met my friends! At first, I thought what they were doing
was wrong, just because it was different...
EMILIO
But they showed me it's fun to try new things!
Together, we learned how to debug — find and fix mistakes in code!
EMILIO
When we have a bug, we have to understand it first.
We need to know what happened, and why it's a problem.
EMILIO
Problem-Solving Steps
1. Understand the problem
Then we plan a solution — we think about what should happen instead,
and how we could do that.

Problem-Solving Steps
Once we have a solution, we try it.
Finally, we reflect on the solution — see why it did or didn't work!

...Okay, that was one way to do it! You gotta think outside the box sometimes!
EMILIO
Meanwhile, Brick...
Woah. Being in here is so...weird.
BRICK
Hey, is that really me? I look pretty hilarious, to be honest!
BRICK
...Yeah. I could never forget that I'm Brick, a popular MyBlox live streamer!
BRICK
But...is that all I am?
BRICK
No, hold on. These new people in my Talk-It...that's right, I made
real friends recently! I even told them that my real name's Derrick.
BRICK
We streamed together to fight back against Wolf!
They taught me all about coding, including my favorite — loops!

Repeating everything is fun, but I have to remember to ask myself:
What code needs to repeat? What code doesn't need to repeat?
BRICK

Code that doesn't need to repeat can go before the loop, above the arrow! That way it'll only run one time.

...I got it! Since 'jump to' loops repeat forever, any code that comes after a loop would never run. So no point in adding code there!

Meanwhile, Valeria...
...So this is my mirror, huh? Always trying to be a million things at once...
and trying to be perfect at all of it.
VALERIA
...Heh. I see. Maybe seeing myself like this would've bothered me earlier...
but it won't work on me now.
VALERIA
After all, I already know how it feels to doubt myself, to feel the pressure...
but my friends pulled me back to the surface.
VALERIA
It's okay if I'm not always the leader, because my friends
can be great leaders too. Which reminds me...
VALERIA
Luz caught me up on what they learned at Underwater Galaxy.
Some bots needed loops, and some didn't.
VALERIA
They looked at each bot's purpose in a puzzle to figure out which ones needed loops, and which didn't. I wish I could've tried it myself, but...
VALERIA
I'm proud of them for figuring it out. And proud of myself for not giving up throughout this whole adventure.
VALERIA
Ah, there we go...I see the way out.
I'm sure everyone else is figuring this out, too.
VALERIA
Just a few puzzles ahead, and we'll reunite. Let's do this! Star Transformer...
VALERIA
Make me a star!
EVERYONE
Keep Going!

Part 3
Alright, I finished all the puzzles...but what's with this huge mirror?
LUZ
Luz, you're here too! Thank the stars you're okay!
JAZMIN
...Aaand I'm out! Woah, a big mirror?! Should I break this one, too...?
EMILIO
Wait, you literally broke your mirror to escape? Now I wanna try that!
BRICK
Oh cool, everyone's here. I don't think we need to break anything...
look at the mirror.
VALERIA
...It's reacting to all the stardust we gathered?
Does that mean we have enough to make a new star?
LUZ
Yeah, looks like it! Hey, I have an idea for a design — everyone, smile!
BRICK
JAZMIN
...It's the reflection of all five of us!
What a wonderful idea, Brick!
Ha! Cordy and Lem will be furious if they see this.
VALERIA
EMILIO
Speaking of Cordy and Lem —
look, they're about to leave! Let's hurry!
You...?! How did you all escape?!
LEM
Ugh...I should've seen this coming. I had a feeling
the stars here might still react to strong wishes.
CORDY
What do we do now?? Get the giant net again??
LEM
Calm down, Lem. Our spaceship is their only way out of here...
I'm guessing you all want to make some kind of deal, right?
CORDY
That's right. You two would look bad if Wolf knew we
escaped under your watch, yeah?
VALERIA
If you take us directly to him, we'll keep quiet about that.
We'll even act like we tried to escape, but you stopped us.
VALERIA
...Keep talking. Why do you want to see Wolf in the first place?
CORDY
Because...we're ready to settle this. For good.
LUZ
W-what?! You really think you stand a chance against Wolf??
LEM
Of course we do! Look at all the galaxies we restored already —
the number of Wolf stars keeps going down!
EMILIO
And because of that, people are starting to remember their real wishes
and passion! Wolf might still have supporters, but so do we!
BRICK
Y-yeah!! Plus, we've taught a lot of other stations how to make their own stars by coding! So...the galaxies will keep getting more and more diverse!
JAZMIN
...Tsk. Fine, you have a deal. At least we know what you're
doing if you're all with us.
CORDY
Grr....whatever!! I'll go let Wolf know we're coming! Don't bother me, okay??
LEM
This is it, everyone. Next time, we'll face Wolf —
we better think of a few different plans.
VALERIA
...Yeah. We can do this. After all, the people we've met
along the way have placed their hope in us.
LUZ
And I believe in us, too. Is everyone with me?
