It's next day and Chef Pee Pee already waking up, looking grumpy.

Chef Pee Pee: *Yawn* Oh man, another worst day for me.

He went downstairs and saw Marvin calling out someone.

Marvin: Jeffy! Jeffy! Where are you?

Chef Pee Pee: Hey Marvin, what's wrong?

Marvin: I can't find Jeffy anywhere! Jeffy! *Sigh* Jeffy!

Chef Pee Pee: Wait, can I find him too?

Marvin: Sure, go ahead.

Chef Pee Pee: Alright, I'm gonna go outside to check if he's there.

House, Outside:

Brooklyn Guy was taking a mail out, it's a letter.

Brooklyn Guy: Hm, what does it say this time... "Zero is destroying our world, SEND HELP!!! - The SMG4 Universe". Is this some kind of joke? Ugh. (Note: He along with other SML characters aren't aware that multiverse exist.)

Chef Pee Pee: Jeffy! Jeffy! Come out right now! Where did you go, you little brat.

Brooklyn Guy: Hey, Chef Pee Pee. What are you doing?

Chef Pee Pee: I'm trying to find Jeffy! He's nowhere to be seen!

Brooklyn Guy: Can I have the cops investigated?

Chef Pee Pee: Of course! Sir! I need the information!

During Police Investigation

Brooklyn Guy: So sir, when was the last time you see Jeffy?

Marvin: Last night, I put Jeffy to sleep by telling a story that he should listened. But then the next morning, he's gone!

Brooklyn Guy: Ok...wait....did you tell that robot legend story to your son?! Dude, have you heard the rumor? A portal will opened up because you told your son the legend!

Chef Pee Pee: A-a portal?! Wait, it-it can't be real, right?

Junior: Hey Chef Pee Pee!

Chef Pee Pee: What do you want, Junior?!

Junior: Um I saw some strange magic outside of our house.

Brooklyn Guy: Wait, could it be the portal?!

Marvin: Oh no...Jeffy must have entered that portal! I need to find that portal!

Brooklyn Guy: Wait sir! Don't!

Chef Pee Pee: I'm coming too!

Chef Pee Pee and Brooklyn Guy chased after Marvin through the entrance door.

House, Outside, near portal:

Marvin: Don't worry, Jeffy! Daddy's gonna save you!

Brooklyn Guy: Wait, stop! You're not supposed to go in! It's too dangerous!

Marvin: What if something's bad happened to him?!

Brooklyn Guy: No worry, I'm gonna find him.

Chef Pee Pee: *Gasp* I want go to!

Brooklyn Guy: What dude! You can't!

Chef Pee Pee: Look, I don't care if I can't do this. But I always risk my life saving Junior and the other brats!

Brooklyn Guy: Ok fine, you can join with me. Anyway, be careful what's in there.

Chef Pee Pee: *Deep Breath* Ok, here I go.

And so, Chef Pee Pee and Brooklyn Guy went into the portal together.

Marvin: Good luck guys! I'll pray for you both to get Jeffy back!

???, Alleyway:

Chef Pee Pee: Ugh....where am I....?

Brooklyn Guy: Hey, Chef Pee Pee? Are you alright?

Chef Pee Pee: Why am I feel so different? I-HUH?!?!

Chef Pee Pee looks down and saw, hoofs! And then he realized, he was turned into a male pony!

Chef Pee Pee: W-what's happening to me?! B-Brooklyn Guy! You also look different!

Brooklyn Guy: What are you....What the f....

Brooklyn Guy, for some reasons, has the body of a mare but is now a pegasus!

Brooklyn Guy: Yo! I have wings!

Chef Pee Pee: What's that thing on my head?!

Brooklyn Guy: I think that's a horn. Wait, that means you're an unicorn!

Chef Pee Pee: Can it glows and carried stuffs? Alright let me try to do this.

Chef Pee Pee tries to lift up a barrel nearby using the horn but it doesn't work!

Chef Pee Pee: Why it isn't working?!

Brooklyn Guy: Dude, you have to learn to use properly.

Chef Pee Pee: Then how am I supposed to know about all of this?!

Brooklyn Guy: Anyway, I think Jeffy must be somewhere in this pony world.

Chef Pee Pee: Oh my god, Jeffy! Where are you?!?!

???, ???:

Chef Pee Pee: Jeffy! Jeffy! Come over here right now!

He then bumped into two ponies!

Ellie: Hey! Watch where you going!

Chef Pee Pee: Oh god! I'm so sorry! I was in a hurry! By the way, where are we?

Ellie: You're in Equestria! Ponyville is where you are right now!

Chef Pee Pee: Ok thanks! Bye!

Equestria, Ponyville:

Brooklyn Guy: Jeez dude, you don't have to be that hurry.

Chef Pee Pee: I know! But what if Jeffy is in danger?

Brooklyn Guy: Same but we have to keep finding him.

Chef Pee Pee: Ok...Jeffy! Where are you?!

Chef Pee Pee then ran back but he accidentally bumped into the same ponies again!

Ellie: Dude! Are you blind?!

Chef Pee Pee: I'm sorry again! I'm finding someone!

Brooklyn Guy: Sorry about my friend. Anyway have you seen Jeffy anywhere?

Ellie: Sorry dude. We don't know him.

Brooklyn Guy: *Sigh* Come on Chef Pee Pee, let's go.

Chef Pee Pee turned around but then bumped into Ellie and Sven again!

Ellie: Oh my god! Stop bumping to us!

Sven: What was that?

Ellie: So some two ponies are trying to find someone called Jeffy.

Sven: Anyway, Ellie. Let's keep finding Henry and Dave.

Equestria, Alleyway:

Chef Pee Pee: That's it! I give up! Jeffy can find the portal himself!

Brooklyn Guy: Dude already? Chef Pee Pee it's been like seconds and you decided to give up finding Jeffy?

Pony: Hey um excuse me?

Chef Pee Pee: What do you want from us?

Pony: Oh um, are you the new visitors come here?

Brooklyn Guy: How do you know?

Pony: I know everything about Dimensional traveling! Anyway.

Twilight: My name is Twilight Sparkle, I know where your friend is.

Chef Pee Pee: Really?!

Twilight: Yep, he came to this world before you guys! Kinda reminds of someone.

Brooklyn Guy: What's wrong?

Twilight: Well you see, there's was a boy who ran away from his home dimension thanks to his abusive life from his family and people at school. We did so hard to help him though the dark moments he had.

Chef Pee Pee: Oh no...

Chef Pee Pee's thoughts:

Jeffy: Why do I deserve this?! All I get is pain and abuse! Mommy and Daddy hated me. All of my friends hated me. Everyone in the world hated me. Even the aliens f*cking hated me! THAT'S IT!!!! I CAN'T TAKE THIS ANYMORE!!!! I. WANT. OUT OF THIS WOLRD!!!!!

Back to the reality:

Brooklyn Guy: Chef Pee Pee? Are you ok?

Chef Pee Pee: Is this what happened? So that boy ran away because of the people from his home dimension hated him? What if something similar happened to Jeffy as well?!?!

Brooklyn Guy: Dude chill! It's not going to happen in reality!

Twilight: D-did I scared you?

Chef Pee Pee: I'm so sorry! Twilight! I didn't mean to!

Twilight: Oh! It's fine! By the way, I haven't got your name yet. What's your name?

Brooklyn Guy: Oh I'm Brooklyn T. Guy!

Chef Pee Pee: And I'm....um...Fernando and my nickname is Chef Pee Pee though...

Twilight: That's a bit strange for you guys to be named like that, but anyway, good luck trying to find your friend!

Chef Pee Pee: Alright! Thank you Twilight! We gonna go now!

Twilight: Bye guys!

Brooklyn Guy: Bye!

Equestria, Ponyville:

Chef Pee Pee: Wait! Is that...

Chef Pee Pee spot someome pushed another away from someone! It was Jeffy!

Ellie: Hey! Are you ok?

Jeffy: Hey thanks for saving me! My name is Jeffy!

Ellie: Anyway, there's no time! Go find somewhere to hide!

Jeffy: Ok, pretty lady!

Chef Pee Pee: Jeffy! I found you! Your dad is so worried about you!

Brooklyn Guy: Hey kid! Are you alright?

Jeffy: I'm fine, guys!

Chef Pee Pee: Um, guys. Look up in the sky.

They saw the same pony from earlier fighting with another pony with cyborg parts!

Jeffy: W-what's going on here? Why are there two ponies fighting in the sky?

Brooklyn Guy: Alright you know what? I got this.

Chef Pee Pee: Wait! Don't do it!

Equestria, Sky:

Brooklyn Guy: Alright! Alright! You two! That's enough!

Revenged!Henry: Hey! Who are you?

Brooklyn Guy: I'm a cop jeez! I'm here to stop this fight!

Sven: Is that the same guy from earlier?

Ellie: Dude, you weren't even wear your uniform.

Brooklyn Guy: No! I am right now! *Looks down* Wait, where's my cop outfit?!

Revenged!Henry: Get out my way before I-

Ellie managed to kick down Revenged!Henry! Revenged!Henry fell to the ground.

Revenged!Henry: This is all your fault, stranger! I will be back!

Revenged!Henry flew away.

Equestria, Ponyville:

Brooklyn Guy: Hey, are you alright?

Ellie: Yeah I'm fine.

Sven: Ellie! Henry is here!

Ellie: Henry!

Ellie flew down and hugged Henry!

Ellie: I'm glad you're ok! What? What do you want to tell me? You found a portal? Ok we're follow you!

Chef Pee Pee: Wait! I just want to say thank you for finding Jeffy!

Ellie: Oh um, you're welcome.

Brooklyn Guy: Yeah, Chef Pee Pee saw everything going on and he saw you saving Jeffy from someone! Alright, time to go home guys!

Jeffy: Bye pretty lady!

Ellie: Um bye? Alright, let's go to the Everfree Forest!

Chef Pee Pee: So Jeffy, what happened back before?

Jeffy: It all started with me waking up but then I saw some light outside of the house so I went outside to check it but then I got sucked in and now I end up here!

Chef Pee Pee: Kid, you made your dad worried!

Brooklyn Guy: Found the portal!

Chef Pee Pee: Anyway, Jeffy. Let's go home.

The three entered the portal and it disappeared.

SML World, House, Outside:

Chef Pee Pee: We're back!

Jeffy: Daddy!

Marvin: Jeffy!

The two ran toward each other and hugged!

Marvin: I'm so glad you're ok!

Jeffy: So the rumor is real, but I still don't believe the legend is real.

Marvin: Jeffy!

Brooklyn Guy: Job's all done! Chief will be really shocked about this when I told him about this!

Chef Pee Pee: Guys! Look! The portal has disappeared!

Brooklyn Guy: Alright guys, it's time to apart together! That was fun traveling to another dimension with you, Chef Pee Pee!

Chef Pee Pee: T-thanks?

Marvin: Alright Jeffy, let's go back inside.

Chef Pee Pee: So what Woody said, does multiverse really exists?

Marvin: I'm not too sure about this.

Chef Pee Pee, Marvin and Jeffy went back inside the house and Brooklyn Guy went back to the police station.

Epilogue:

Junior: Hey Chef Pee Pee!

Chef Pee Pee: What do you want, Junior?

Junior: Can you tell me a story you went through?

Chef Pee Pee: Let me tell you the story, that was crazy! I turned into an unicorn in a world filled with ponies!

Junior: Um, what? Is this real? Don't tell jokes.

Chef Pee Pee: Oh my god. You're just like Jeffy.
