In Planeptune:
Noire was walking in Planeptune as she goes to Neptune's church.

Noire: It's been a while since the last time I came to Planeptune.

Noire enters the church.

Noire: Neptune, I've come to visit... huh?

Noire notices a big thing by the middle as no one was here.

Noire: They all went out?  Even Histoire and Nepgear aren't here... Well, whatever, I'll wait here for a bit.

Noire lays down on it as she relaxes.

Few moments later:
Noire was reading a book still laying down.

Noire: W-What am I doing? I'm no different than Neptune if I do this!  N-No, I'm doing my job well, so taking a break is fine. No one ever complains about my work! Yeah! I'm not like Neptune at all!

She sits there for a couple of seconds.

Noire: So bored... I wonder what everyone's doing... It's not like I'm lonely or anything. Maybe they all went to another nation? Ah! Maybe they're visiting my place... Like hell... Even if that was true, Histoire would still be here. Or maybe she's finally doing her work seriou- Of course not. That can't be right. There's no way!               

Neptune: How rude! I'm still here doing my work properly!

Noire: Yeah, yeah. Only when Histoire gets angry, right... Huh?!

Noire then notices Neptune's voice out of nowhere.

Neptune: Up here!

Noire: U-Up?

Noire looks above her as she was laying on Neptune who is big and fat.

Noire: Wh... What's going on here?! What! Why?! How did you become such a fatass!

Nepgear: Noire! My sister is not a fatass!

Noire hears Nepgear's voice.

Noire: That voice... Nepgear?! Where?!

A hand pops up from Neptune as it was Nepgear.

Nepgear: She's just a bit chubbier than most people!

Noire: You're in there?! No matter how you look at this, she's clearly gotten fa-

Sonic: Ngh... Ngggg...!

Noire: Sonic?! You're in there too?!

Sonic forces himself out from Neptune.

Sonic: Phew, I finally got out of it.

Neptune: By the way, Noire. You said you were gonna "kick back" earlier, right? That's not very ladylike, you know.

Sonic: Mhmm.

Noire: I don't want to hear that from you two now! Anyway, how did you end up in this state?

Neptune: Umm... I don't even know myself.

Sonic: It was when we were doing a quest by the forest.

Neptune: Oh yeah, that! It was what I did recently...

Noire: Eh? A flashback now?

Neptune: We were on our way, doing our quest seriously. We were so serious. We tore right through our enemies! I wish I could show you that.

Noire: I don't care! Hurry up and just get on with it already!

Neptune: And then I realized... That I forgot my lunch. And then my hungry little self...

Noire: No that's fine. I can already guess the rest.

Neptune: Don't say that. Please listen to the end.

Noire: Well, you ate that thing after all, right?

Neptune: First I tried smelling it. Throughly...

Noire: Even though you ate it, right?! Hurry up and eat it!

Neptune: Why?!

Noire: And why are you suddenly looking this way?! So annoying!

Sonic: Noire, that's kinda her thing.

Neptune: And then I ate it whole.

Noire: Good! Now you finally ate it!

Neptune: Not!

Sonic: Hahaha!

Noire: Argh! Why did you spit it out?!

Neptune: We'll, I ate it anyway and became like this.

Noire: I could see that two pages ago! That was unnecessarily long!

Histoire: What Neptune ate was a poisonous mushroom called "Just Get Fat."

Noire: Histoire?!

Histoire: It only makes the one who ate it fatter, but...

Noire: I can't even see you!

Histoire: If it continues like this, our Shares will go down... and even more, I and Nepgear will die from the lack of oxygen...

Noire: Enough! I get it! I get it! What should I do now?!

Sonic: You mean we.

Histoire: There's a mushroom that can cure the effect of "Just getting fat." It's called "Just shrink." Please bring one back here.

Sonic: Got it!

Noire: Ah... huh... okay...

Neptune: Sonic... Noire... You're the only two I can depend on now... What did a little girl like me do to deserve this? The last chapter of this could even be a fat joke... Only you two can put an end to this nightmare... so please...

Sonic: Neptune...

Noire: (Ah... So she was hurt this much...) I guess there's no other way. A mushroom hunting quest shouldn't take long, so just wait here, okay?

Sonic: Yeah, we'll be back here in a flash!

In the forest:

Sonic: You know, this is the first time we've done a quest together.

Noire: Yeah, you're right.

Sonic: You said you do a lot of quests in your nation and it sure tires you a lot, huh?

Noire: Of course. I can never do the things I want to do.

Sonic: We'll then, why not I help you?

Noire: Huh? You?

Sonic: Yeah, I'll do the quests for you.

Noire: But it's my nation, it doesn't-

Sonic: Enough of that, would you. We're friends, aren't we?

Noire: Fr-Friends...

Sonic: Hmm? You said something?

Noire: Huh? No, nothing. I-I guess you can help out, since you ask. It's not like I wanted you to help me or anything.

Sonic: Hehe, always you, Noire.

Noire blushes as they found the mushroom.

Noire: Well, that was easy, much easier than I expected.

Sonic: Okay then, let's hurry and-

Suddenly, they noticed Planeptune's basilicom was getting destroyed as Neptune was huge.

Sonic: What the?!

Neptune: She... She evolved!

Blanc: Hey, what the hell is that?

Vert: Is that Neptune?

Blanc and Vert were in their HDD forms.

Sonic: Oh, Blanc, Vert.

Noire: Why are you here?

Vert: We saw a report that a monster has appeared in Planeptune, but... just what is going on here?

Noire: Well... it's a long story...

Blanc: If it's a long story, tell us later.

Blanc rushes in first and grabs her axe and smashes the ground where Neptune stands on as she was in the air. Blanc flies towards Neptune and tries to carry her.

Blanc: Urgh... Shit...! So frickin' heavy!

Sonic: Now that's power...

Blanc: Hey, you two! If you the reason for this then you must also know how to fix it, right?!

Noire: Y-Yeah! If she eat this she'll return to normal!

They both look to see a mushroom in Noire's hand.

Blanc, Vert: Mushroom?

Sonic: Yep, a mushroom.

Vert: Well then, no need to drag it on any longer. (Why a mushroom...?)

Noire: Neptune, you heard us right? Open your mouth!

Neptune: Urgh...

Sonic: She's not opening her mouth.

Noire: Ah! I've heard about this! When a whale drifts ashore, it's weight leads it to death immediately. It's the same with Neptune. Becoming fat made it so that her muscle couldn't support her jaw anymore! That's why she can't even open her mouth now!

Sonic: *Sarcastic* Wow, great explanation, Noire.

Noire: Are you being sarcastic again?

Vert: In that case...! I'll pry it open!

Vert flies up to Neptune's mouth and opens it up.

Sonic: Whoa!

Vert: I can't, hold it on much longer...

Sonic: Vert, hold on!

Sonic jumps up from building to building up to Neptune's mouth helping Vert.

Sonic, Vert: Ngh...!

Sonic, Vert: Noire! Do it now!

Noire: I'll do it in one shot!

Noire goes into her HDD form and throws the mushroom into Neptune's mouth as Neptune starts turning back to normal.

Noire: Mission accomplished.

Neptune: Wahh! I'm falling!

Sonic: Neptune!

Sonic dives down and grabs Neptune as he carries her princess style.

Sonic: Phew, that was close. You okay?

Neptune: Yeah, thanks to all of you!

Sonic: Hehe.

Everyone else goes to where Sonic and Neptune are as food was getting ready.

Few minutes later:

Sonic and the others were eating BBQ as Neptune takes a bite of it.

Neptune: Wow! This is so delicious!

Sonic: Mmmm...!

Noire: Hey, Neptune! Have you really reflected on your actions?

Neptune: I have, I have! I already thanked you! Having friends is really a good thing!

Noire blushes at what Neptune says.

Neptune: Especially you as my warrior, Sonic.

Sonic: Hehe.

Noire notices Neptune with a bunch of mushrooms.

Neptune: Oh, those mushrooms...

Sonic: Hmm?

Noire: Aren't they "just shrink" mushrooms? There're still this many?

Neptune: I didn't know how many were needed so I picked a bunch.

Blanc, Vert: Eh? Is that really alright?

Neptune: Alright! Let's eat these too!

Sonic: Huh?

Noire: What?! Haven't you learned anything?!

Nepgear: Ehh? If we eat this maybe we become slimmer. It's a food that every girl has ever dreamed of!

Histoire: There's no way it can be that convenient.

Neptune: Thanks for the meal!

Sonic: Neptune, I don't think that's a good-

Neptune already eats the mushroom as smoke covers the the area.

Sonic: Huh?

The smoke clears out as Neptune shrinks into a small Neptune as her clothes were on the floor. Sonic blushes badly and turns around.

Sonic: W-Wha?!

Noire: That's it, I'm done! You just learn your lesson!

Neptune: At least the punch line isn't my boobs shrinking or anything!

Sonic: Ugh... Oh, Neptune...
