You all returned to Flipside. 

Tippi: I can't believe it! Five out of the eight Pure Hearts in such a short amount of time! 

Bowser: Gwah ha ha ha ha ha ha! What'd I tell ya, huh?! You've got the king of all evilness on your side! You can't go wrong!

(Y/N): Yeah, you've been a big help. 

Tippi: That said, we owe Squirps for helping us find this one... We should be grateful...

Weiss: Yeah, he may have been kind of annoying, but he did mean well in the end. 

(Y/N): Yeah, that's true. Say, Tippi, you see a lot more cheerful now. 

Tippi: You think so? Well, I guess ever since you guys saved me from Francis, I've been in a good mood! (Y/N), I think I could hang around you forever. 

(Y/N): Uh ... 

Tippi: (blushing) Tee hee. 

Merlin then appeared. 

Merlin: Ah, welcome back my friends. 

(Y/N): We went into Outer Space this time Merlin! 

Tippi: Yes! And this- AAAAAAAAAGH! 

Tippi soon felt pain as she collapsed. 

Everyone: TIPPI! 

Merlin inspected her. 

Merlin: What has happened? All of you, come to my house at once! Hurry, now!

You picked up Tippi and everyone followed Merlin to his house. 

Merlin: Very well, let's all take a breath and gather ourselves here... I'm concerned... Tippi may be unable to maintain her Pixl form for much longer.

Bowser: Her Pixl form? 

Rin: Tippi wasn't always a Pixl? 

Merlin: Yes. She was originally a human. 

Everyone: WHAT?! 

(Y/N): Tippi was a human in the past? What happened to her? 

Merlin: I don't know. I found her exhausted, cursed to wander through dimensions forever. She was on death's door when I found her. And so I used my ancestor's magic to save her. She transformed into a Pixl. Tippi isn't even her original name. 

Ruby: But where is Tippi from? 

Merlin: She had lost her memory, so I have no idea who she is or where she is from... But I can't help thinking she did not come here by chance. Fate connects us... And my intuition in this are is rarely mistaken.

Then another tremor occurs! 

(Y/N): Shit, the Void is growing. 

Merlin: Indeed. Head to the next Heart Pillar. Go through the mirror hall first though. 

Everyone: Mirror Hall? 

On one of the lower levels of Flipside, there was a building with a massive mirror. 

(Y/N): Hmm ... what did Merlin mean by- 

You put your hand on it, and you fell through. 

(Y/N): WHOA! Uh ... guys? 

Everyone: Yeah? 

(Y/N): You got to see this! 

It was Flipside in reverse! 

Blake: What's going on here? 

???: Ah, welcome. 

A figure who looked like Merlin but with a purple outfit appeared. 

???: I figured you would come. 

Jeanne: Merlin? But we- 

Merlin: I can see that you would like to ask me where in the world we are! Ho oh oh ho! This place may seem like Flipside, but do not be mistaken! You WERE in Flipside, but then you flip-flopped sides... Friends, you are in Flopside!

Pyrrha: So, you're not Merlin. You're his counterpart here? 

Nilrem: That's right. My name is Nilrem. 

Weiss: So, it's Merlin spelled backwards? 

Nilrem: Yes. There is a front and a back to all things, young ones. Now, the Heart Pillar is one floor up! Go and place the Pure Heart within it! See you!

Later... 

You guys place the Pure Heart in the Heart Pillar and a light blue door appears on the top of the Flipside Tower! 

Back at the tower... 

You all found Merlin, with a recovered Tippi! 

Tippi: Oh good, you guys are back. I'm feeling better now! 

Merlin: Are you sure, my dear? 

Tippi: I'll be fine. This is no time to stay in bed. My friends need me. 

(Y/N): Great! Let's go! We still got three more Pure Hearts to find before we take on Count Bleck! 

Everyone nodded as you all entered the next door. 

Soon... 

The door lead to a prehistoric-like setting. 

(Y/N): Hey ... this seems off. 

Bowser: Really off. 

Nora: And ... windy. 

Ruby: Almost like we're- 

Everyone: IN THE AIR?! AAAAAAAAAAAAGH! 

You all fell down as two cavemen danced. 

Caveman: Cragga wagga woo! 

Caveman 2: Craggit daggit yoo! 

Caveman: Brah! Big Rock Who Watches! Cragnons just little rocks! Cragnons need help! You hook Cragnons up, brah! Or Cragnons go CRONCH and then no more Cragnons!

Then you all landed, with Blake landed on her feet. 

Luckily Peach had her parasol to float down safely. 

Cragnon: Oh, Crag! 

(Y/N): Huh? 

Ruby: Cavemen? 

Cragnon: Whoa... Skarn! You see persons drop out of sky, brah?

Skarn: Yah, Jasperoid... Thought I was losing my crag, brah. Persons shaped weird, huh? Wait! You think maybe...persons sent down to help by Big Rock Who Watches?!

Jasperoid: They look weird, brah. 

Skarn: Bite your crag, brah! Do not doubt power of Big Rock Who Watches!

Jasperoid: Point well cragged, brah.

(Y/N): What are you guys talking about? 

Jasperoid and Skarn: Follow us, brah! 

They began walking off. 

Bowser: Geez, this is getting confusing. 

(Y/N): We'll just have to take what we can get! Come on! 

Soon... 

Skarn and Jasperoid lead you all to their leader. 

Cragnon Chief: Servants...of Big Rock Who Watches... You big boulders, we just gravel bits...

Tippi: Where in the world are we? And what are you...things?

Jasperoid: This is land of Cragnons. Me Cragnon, him Cragnon, this land of Cragnons.

Skarn: It not rocket science, brah. Anyway, big brah here is Marbald, chief of all Cragnons.

Weiss: What seems to be going on then? 

Marbald: One day...freak plant-people came... Nerd Cragnon named them Floro Sapiens. They kidnap many Cragnobs... We were peaceful brahs... They give peace no chance... Rescue team of Cragnons...now need to BE rescued... We at end of our crag... How do we save Cragnons? No ideas come to Marbald...and we keep losing Cragnons... This bad, brahs... Cragnons must work this out, or Cragnons go ex... EXTINCT, BRAH! 

(Y/N): Don't worry, leave it to us! 

Marbald: Yah? You not cragging my chain? 

(Y/N): Nope. We'll do it because it's what heroes do! 

Team (Y/N): YEAH!/I'm only here because it's convenient.

Jasperoid: You rock, serious!

Skarn: Yah, serious, no cragging! Big Rock Who Watches sent you to Cragnons, for sure!

You all left the house to see some flower people appear. 

Floro Sapien: Hey, check it out, man! Haven't seen these people before. 

Floro Sapien 2: Yeah, rare breed, totally! Sweet timing, too! We need a Pure Heart polisher! Score!

Pyrrha: Pure Heart? You all know about the Pure Hearts? 

(Y/N): So, you guys are the Floro Sapiens! 

Floro Sapien: HA! Our mighty leader, King Croacus will be stoked to have rare breeds! Come on man, let's tenderize it and- 

You took them out easily. 

(Y/N): Alright, where are the Cragnons. 

Floro Sapien 2: D-Down in the Floro Caverns. Please don't- 

???: HEEEEEEEEEEEEEEEEEELP! 

Tippi: What the? 

Blake: OVER THERE! 

Blake pointed as some Floro Sapiens were carrying a bunch of Cragnons away from the village! 

(Y/N): AFTER THEM! 

You all began to give chase! 

The chase lasted for quite a while until... 

???: NOT SO FAST! 

(Y/N): Oh no, that voice. 

Tippi: It's him again. 

O'Chunks appeared. 

Ruby: Who in the- 

(Y/N): O'Chunks, he works for Count Bleck! 

https://youtu.be/8PpAU6oZeXI

O'Chunks: GRA-BLAGHY! I've not been made teh wait like this since that fine lass stood me up long, long ago! Yeh did this teh break me concentration, didn't yeh?! Yeh likes the cheatin', eh?! Sorry teh disappoint yeh! Yeh think I'd fall fer a bush-league move like that?!

Jeanne: This guy seems- 

Weiss: Like a massive idiot. 

Blake: Not to mention very misguided. 

O'Chunks stomped the ground in anger. 

O'Chunks: "Misguided"? That's not even a real word, yeh pest! Quit yer yappin', now! It's time fer us teh settle this once an' fer all!

Bowser: Hey O'Fatty! You seem like you need a good stomping! And I'm a licensed Stompologist! 

Peach: Bowser, don't. 

O'Chunks: Stompo- ARGH! Big talk coming from a oversized turtle! 

Bowser: Big talk coming from a hairy idiot! 

O'Chunks: I'll be wanting an apology! In writin' An' I want it written with yer Face! 

???: Why salutations, O'Chunks! 

Dimentio appeared. 

(Y/N): Dimentio?! 

Ruby: Not this jerk again! 

Dimentio: Ah! Once again we meet, like two large, hairy vikings on a storm-tossed schooner!

O'Chunks: What d'yeh want, Dimentio?! I don't be needin' any help! Yeh'll just get in the way!

Dimentio: Ah, a quadrillion pardons! Far be it from me to be a hindrance. Far, FAR be it! As it happens, I merely have an acquaintance in this land. I was just saying hello!

O'Chunks: Is that so? 

Dimentio: Yes, truly! And I saw you, and I thought that my magic could aid in this fight! 

He cast his spell, and transported everyone to Dimension D. 

Peach: This again? Dimentio, this didn't work last time, what makes you think it would work this time? 

Dimentio: That's because I won't be doing the fighting he would! Fight to your heart's content! Ciao! 

He then teleports away. 

O'Chunks: Wuh... That doesn't sound too bad, I guess. Maybe I misunderstood that weirdo... Well, anyway, you lot are in fer it now! Meet the new-an'-improved O'Chunks!

He began to charge to attack, but you easily dodged him again. 

(Y/N): See? He's so predictable. 

Everyone was doing the same as you. 

Pyrrha: Wow, he is. Uh ... sorry about this O'Chunks. 

Pyrrha used her Semlance to hold the metallic parts of his clothes together, and- 

Bowser: HA! NOW THIS IS THE RIGHT MOMENT! 

Bowser easily beat him with one punch! 

O'Chunks: NOOOOOOOOOOOOOOOOOOOO! 

You all got taken back. 

O'Chunks: BLARGH IT ALL! Bad enough that yeh beat me once, but twice is too much teh bear! How can I show me face teh the count now, eh? I CAN'T! Put me out o' me misery!

(Y/N): Whoa! Whoa! I'm not doing that. You don't seem like a bad guy too me. 

Ruby: Yeah, he doesn't seem as bad as Mimi and Dimentio to be honest. 

O'Chunks: Just get on with it! I'm serious! I've no regrets! Well... No... Perhaps I do regret not confessin' me love teh that sweet lass... BUT NO! That's no way fer a brave warrior teh talk when 'is time comes 'round at last! So... Do it! Now! NOW! 

???: Why salutations O'Chunks! 

Dimentio returned. 

O'Chunks: Di-Dimentio! Look, honestly, this is kind o' important! How 'bout some privacy, eh?

Dimentio: Yes, yes, of course, I understand. Your honor must be satisfied... But, O'Chunks... Before you let your game be over, humor poor little me for a bit. I have something I rather think you'll enjoy. I DO wish you would try it out for me.

O'Chunks: YEH CRAZED LOON! It's not the time fer...

Dimentio: Oh...it's not the time, hmm? Not the time for something that will aid Count Bleck?

O'Chunks: Ooh... Fer the count, eh? Well, that do change a thing or two... Hmmmm... .......................................................... ..................................................................... ......................................Fine, then! You lot! Yeh took enough of a beatin' fer today, so I'll let yeh off easy-like! I tell yeh this, though: yeh better work on yer skills by the next time we meet!

Weiss: But didn't you say you couldn't show yourself to your boss before? 

O'Chunks: 'EY! SHUT IT! I live fer the count! I couldn't end me life without 'is say-so! Me heart is weak, sure, so I'm done with it! From now on, I'm all brawn, no brain! The past be nothin' teh me! All that matters is Count Bleck's future! All fer 'im! Chunks away!
Dimentio: Ah, it is time to part... Ciao!

The two then left. 

Bowser: What a baby. 

(Y/N): Eh, he's fine. Come on, I sense that the Floro Sapiens are going down underground. 

Nora: This should be interesting.
