In Mewni, we see Infinite was standing on top of the castle roof. He has the golden gauntlet on his left hand. King Butterfly and Marco were captured from Ludo and his rat's army underground, Black Flame was still searching inside the castle for the Power Stone.

Black Flame: It's not there.. *growl* Such mewman were smarter than what I am expected.

Black Flame kept looking and looking until he notices a small key lying on the ground, he picks up it, he has no idea what it's for but he looked around and sees a secret chest beside the bed.

He walks his way to it, he use the key to open the chest and reveal the Power stone, he made a smirk face. Black Flame teleported outside where Infinite is.

Infinite: You found it?

Black Flame: Yes Infinite, I have found it.

Black Flame reveal the Power stone, gives it to Infinite and place it on the gauntlet.

Infinite: At last, the power stone... I can finally see what it feels like to have this kind of power.

Black Flame: The boss would be proud of you to achieve that.

Infinite: He would be proud

Meanwhile, Star is knocking on the door to Buff Frog's house. Buff Frog opens it, wearing his evening robe and underwear, also revealing that Flame is there as well, his sneakers were in the house and his feet has mud on it.

Moon: *gasp*

Flame: Hey guys, about time your here. It shouldn't take that long for you guys to come here.

Star: Flame! Buff Frog!

Buff Frog: Star Butterfly! *hugging her* Oh, my little sweet potato. It's been too long.

Moon: Ahem.

Buff Frog: Oh, *pulling his robe closed* Queen Moon. *bows* Greetings.

Star: Mom, this is Yvgeny Bulgolyubov.

Flame: What?

Buff Frog: Ah, no, no. Please call me Buff Frog.

Star: He used to work for Ludo, but he's cool now.

Moon: What?!

Star: Hey, Buff Frog, can we crash with you for a night?

Buff Frog: Of course. I owe you for all that tadpole-sitting.

Moon: Star, can I speak with you? *walking out of range of Buff Frog, with Flame as well* We cannot stay with him. He's a monster.

Flame: One, he has changed since after that. Two, stop being racist, treat him fair honestly.

Star: Yeah! Not all monsters are bad. *looks at Buff Frog*

Buff Frog: *smiles*

Flame: It's either stay outside forever or stay inside Buff Frog house, either way, thinking going out... well-

A loud Godzilla roar was heard from outside, Moon, Star, and Buff Frog gulp from the sound of the roar.

Moon: Well, you got a point Flame, I guess we have no other choice.

They begin entering in Buff Frog's house.

Buff Frog: Uh, welcome to my... home.

Star: *poking Buff Frog* Boop.

Inside, Flame, Star, and Moon find themselves in a puddle of mud.

Moon: *gasp*

Flame: Oh yeah, I forgot to tell you about that...

Buff Frog: You're in luck. It's rainy season. *picks up mud, applying it to his head* Ah, so good for the skin. Oh, uh, no shoes in the house.

Star: *smiles*

Moon: *scowls*

Buff Frog: I am, how you say, germaphobe.

Flame: Yeah... kinda like that, sort of.

Star: *throwing off her boots* Ah. I feel so free.

Star walks across the mud, and then willingly falls face-first into it, Flame lie down on the mud so he can relax. Back at home, mobian hedgehog bath is actually mud, they were used to make them smooth and clean because of its fur and body. Flame has something he had in mind, but he's wondering why he's here.

Flame: (Hmm, days later, me and the others were in Ruby world, so we can stop the bad guys from destroying their universe so they can absorb it. But since I'm here, I would probably guess that the bad guys aren't finished yet, but could it be that-)

Before Flame could say anything, Buff Frog's babies leap on Flame.

Flame: What the heck?? Are those-

Star: Yep. And they got little arms, but... expect one tho.

Flame: I can tell.

Buff Frog: Babies, say hello to Queen Butterfly.

Moon: That really isn't–

All the babies jump on Moon, knocking her into the mud.

Flame: Oh my. Hehehehe!

Buff Frog: Star, I have been so worried about you.

Star: Why? I'm good.

Buff Frog: Well, when Ludo took your castle with two things, I thought, you know...

Buff Frog makes a slicing sound while gesturing across his neck. That caught Flame in attention when he heard "two things", he wouldn't imagine or believe it's them.

Buff Frog: Toffee is dead. Ludo in the castle.

Star: Ugh! Toffee not dead. Toffee inside Ludo.

Buff Frog: Oh. That is... so creepy.

Flame: Buff Frog... the two things you say. Are they the different species?

Buff Frog: Yes.

Flame: And the one with a mask and the one that looks like me?

Buff Frog: Yes.

Flame: *sigh* I hate to say it but... That's Infinite and Black Flame.

Star: Wait, you mean the one who was fighting you!?

Flame: How do you know that!?

Moon: A big cube shows us what's happening in the other view.

Flame: *groan* Infinite and Black Flame is far worse than Toffee, Black Flame has destroyed planets and even the universe. Infinite can created illusion and do crazy things!

Buff Frog: But why would they join Lu-ahem, Toffee?

Flame: Hmmm, that's hard... I don't know but I think they joined forces. But there's one way to solve it.

Suddenly, Flame uses his speed to put on his sneakers and head outside to figure out what's happening.

Star: Flame! Wait!

Moon: Star... let him go, he has his duty to do. We can't interfere with him.

Star: But Mom! What if Flame got hurt, or or-or he failed?! Ugh.

Buff Frog: She really cared for Flame huh?

Moon: Yes she does. Star, I'm sure he's going to be okay, he's strong and very smart.

Star: I know mom but-

Moon: Just... believe in Flame and think he is okay.

Star: *sigh* Alright. Thanks anyway.

Moon: Your welcome Star, I'm glad to help you out.
