I'm supposed to read a novel for English,
but Lily's using them all to build a fort.
Ooh, found one. Also a green bagel.
I'll be taking that.
Cool. The main character's named Luna.
And she's got a sister named Luan.
Let me see that. [gasping]
This isn't a book, it's a diary.
Luna's diary. You can't read this.
OM gosh. Of course not.
I'd never invade her privacy like that.
Though I do kind of wonder
what big secret she was referring to.
Big secret?
Mm-hmm.
"But I know I can never tell my fam my big secret that I-"
♪ Back from band practice Where'd I put my key? ♪
Scatter!
[humming]
- That was close. - I know.
As long as we don't read any more of it, we're good.
Be home soon!
Hey, guys, I'm just gathering clothes
for the wash! Got anything?!
[grunting]
[gasping] Okay, we're in. Let's find that diary.
What are you guys doing in here?
Um, uh, collecting laundry.
Laundry day was Tuesday. Spill it.
Okay, fine. We were looking for Luna's diary.
That is so wrong. I can't even joke about it.
I know you're itching to find out
what dear old sis is hiding.
Hmm. Okay, fine. I'll help you guys look.
Eee! I think I found it.
Okay, okay, let me see where I left off.
"But I know I can never tell my fam my big secret,
that I... skipped school last Friday
to see a slasher flick at the mall."
[gasping]
So, Roxy had a great idea to ditch.
Breaking the rules was such a rush. [giggling]
I can't believe this. Luna's been skipping school?
And who's this Roxy girl? She sounds like a bad influence,
we should go talk to Luna right now.
We can't do that, then she'll know
that we've been reading her diary.
[whistling]
Everything okay, Luna?
Yeah, must have gotten bit by a... uh... bug or something.
Hmm.
"Dear Diary, dude, I finally did it,
I got... a tattoo!"
[gasping]
[snoring, creaking] Huh?
- Oh! - Oh!
[groaning]
"Tonight was killer. Instead of studying for finals,
I snuck out to this underground club
with Roxy."
[gasping]
Guys! Luna's turning into a monster.
Look at her latest diary entry!
Luna and Roxy are planning a night of mayhem
in Royal Woods.
First, we fill the town fountain with nacho cheese.
Then, we free all the goats from the petting zoo.
Start some fights at the biker hangout.
Then swipe the big letter R,
from the sign on town hall, baby.
We have to tell Mom and Dad.
But Luna's gonna hate us, for snitching,
and for reading her diary.
Hmm, you both make good points.
Maybe there's a way to stop Luna
without all of that messiness.
So we know Luna's exact itinerary
for tonight's mayhem.
If we can stay one step ahead of her and Roxie,
we can thwart all of their plans
without Luna ever finding out we're on to her.
I'd like to buy your nacho cheese, all of it.
This way there's no cheese left
for Luna to pour into the town fountain.
- Yay! - Same idea with the goats.
If there aren't any for Luna to set loose,
she can't make trouble.
Oh, there you guys are.
Come on, Leni, I think I hear Luna.
Dude, where are all the goats?
Yes! Another plan thwarted.
Open for Badness?
I thought we could keep Luna away
by making it look like it's closed,
starting with unplugging that sign.
There, all done.
Hey, you little punks!
Huh?
Last stop, town hall.
We gotta get there before Luna can steal the big R.
Too late!
- Stop! - Don't throw your life away.
- Huh? - We read your diary!
What?!
We're really sorry for invading your privacy.
I knew you dudes were snoopin' in my diary,
that's why I made up this whole rebellious act.
What?
It all started the other day after band practice.
[humming]
Phew, that was close.
I know. Can you imagine how upset
Luna would be if she knew we read her diary.
So I erased what was really in my last entry,
and made up the story about skipping school instead.
And the tattoo?
Well, what about sneaking out to clubs?
I never snuck out. I just faked sneaking back in.
What about this Roxy girl?
Sam?
Sorry, guys, I had to help her out.
Sorry we doubted you.
It's cool, dudes.
I'm sorry for messin' with you to teach you a lesson.
