Yeah, you're probably wondering why Hazbin Hotel is spelt 'Has been Hotl'? This is intentional cause this is Caboose's Guide. Duh.

BTW, this takes place right over 'Overture' and 'Radio Killed the Video Star', which basically means that there is only six months compared to three months seen in A Hunter's Guide for Running a Hotel. Yeah, it's going to be hugely different now. I hope you'll enjoy it.

Caboose's Guide to make Friends in Hell

Guide Two

I'M NOW PART OF THE HASBEEN HOTL!

Premise: This is the part where I decided to join the hotl where I can make more friends! I hope Charlotte and Baggie don't mind in me making some?

Charlie and Vaggie stared at the tall, blue as they never expected a stranger to suddenly appear in their bedroom and hold Charlie's cat, KeeKee, in its arms. It waved at them in a friendly gesture. "HEEEEEEEEEEELLLLLLLLLLLLLOOOOOOOOO! Would you two like to be friends!?" It was clearly male by the sound of his voice. Yet there was something off-putting about him. He seemed to be friendly. Too friendly for their taste.

In an instant, Vaggie held her spear and pointed at the blue idiot. "Hold it right there!" She spoke with a threatening tone. "I don't know how you got here, but you will explain yourself now!"

"HEAT SIGNATURE DETECTED!" The robotic tone spoke through his Assault Rifle.

This causes Vaggie to look around, confused, before it eventually lands on the blue armoured man's rifle. "Did that gun just fucking speak?!"

"FIRING MAIN CANNON!" The Blue man's rifle spoke.

"NO! Bad, Freckles! Bad!" The unknown man told his rifle as if it was like a pet, making it stop from firing at Vaggie. "The one-eyed mean lady is confused. Please give her a chance."

Vaggie lowered her spear and tried to process what was going on. There is one thing on her mind right now. "Is he treating that weapon like Charlie's cat!? Also, 'one-eyed mean lady'? Is that an insult he's giving me?!"

Speaking of the devil herself, Charlie immediately petted KeeKee when she got over to her lap. She left the bed and looked at the strange man before approaching the two to de-escalate the situation. "Um, Vaggie. I don't think he's going to take your words seriously?"

This causes her girlfriend to look over. "What makes you say that?" Her mind immediately confirmed this to her as she heard the blue armoured man speaking to his rifle with a baby voice. "Oh…"

Charlie cleared her throat, which brought the stranger's attention as he looked at her. "Um…hello. Sorry if Vaggie threatened you since there are…uh…no people that…"

"No one should be visiting the staff's personal quarters." Vaggie interrupted, holding her spear close to her. "You better start explaining right now!"

"Yeah, mean one-eyed lady, about that…" The blue man spoke. "Um, I walked through a door that should have led me to the bathroom…But this isn't the bathroom." Hearing him utter this, she really wanted to facepalm due to the stupidity he is displaying right now.

"The bathroom?" Charlie tilted her head before her gaze shifted to where the bathroom exactly was. "It's right over there."

"Thank you!" The stranger spoke with a childish tone.

"Hold on!" Vaggie immediately spoke, stopping the man in his tracks. "You're just gonna go to the bathroom without introducing yourself?"

"Yes!" The man responded.

Vaggie groaned as she found it hard to even process the situation the man had unintentionally caused. Lucky for her, Charlie was the one who decided to ask that. "Maybe you can go after you say your name. Okay?"

"Okay!" The man immediately answered.

Charlie could make some sense to the man. "What's your name?"

The man is immediately silent. It took a literal ten seconds to pass by before he responded. "I'm Caboose."

Charlie let out a smile upon hearing the name. "Nice to meet you…eh…Caboose!" She placed a hand over her chest. "I'm Charlie Morningstar, and this is my girlfriend, Vaggie."

While Charlie was happy to introduce herself, Vaggie looked at him suspiciously. And was baffled by his name. "What kind of idiot names himself Caboose?!"

"Oh, you two are like Grif and Simmons in that storage closet!" Caboose immediately uttered, causing the two girls to be confused about what he said. Despite this, he greeted them in a friendly way despite having that childlike innocence. "It's nice to meet you, Charlotte Morbinstern and Baggie!"

Hearing their name being mispronounced caused the one-eyed woman to glare at him. "IT'S CHARLIE MORNINGSTAR AND VAGGIE, YOU IDIOT!"

"Yes, Charlotte Morbinstern and Baggie," Caboose spoke her name again.

Vaggie let out a frustrated groan. She wanted to sleep and forget that this happened due to "Caboose's" idiocy. Seeing her distress made Charlie place a hand over her shoulder for comfort. "Relax, Vaggie. He'll get our names right soon."

"Are you serious right now, hon?" Her girlfriend spoke to her with a very deadpan tone. "This Caboose walks into our room, threatening me with his rifle and NOT to mention he mispronounced both of our names!"

"Um…" The two girls turned to Caboose, who seemed to give an innocent gesture despite the tension he had caused. "Why is Miss One-eyed mean lady being like that, Charlotte?"

"She doesn't like it when strangers appear in our room," Charlie answered, ignoring that Caboose had said her name wrong. "And if you want to go to the bathroom, you can go right now before we can ask you some questions, okay?"

"OKAY!" Caboose immediately responded as he turned around and walked in the wrong direction.

Seeing him closing the door caused Vaggie to let out an irritated groan. "Este Pendejo…" She turns to look at her girlfriend. "He went to the wrong door, didn't he?"

"Yep." Charlie nodded with a tired look on her face. "I'm sure he won't take long to figure out he went to the wrong room."

-The Morning After 'Take long to Figure out he went to the wrong room'-

Alastor yawned as he walked to the main room to have a certain maid making a cup of coffee. What he didn't expect upon entering the main area were all the staff members surrounding both Charlie and Vaggie, who sat on the couch. Both were clearly tired as if they had been up all night and still in their pyjamas. Seeing them in this state made the Radio Demon greet them. "Good morning, ladies! I hope you two had a good sleep."

Vaggie looked up to him and glared with the exact tired look. "Alastor, not now!" She wasn't in the mood to talk right now.

Angel seemed to like this attitude. Usually, Vaggie appeared to be the more professional in running their hotel. He looked smugly at her. "Why not, Vaggie? Were you and Charlie busy in your room?" He asked slyly.

Niffty leaned closer to the two ladies. "Yeah, were you two doing it?"

This caused the Princess of Hell to blush slightly at this comment. The other girl, however, only got mad. "It's nothing like that. It's just that—"

"We had a visitor in our room last night." Charlie interrupted.

Now that got everyone's attention. Alastor hummed at his and asked, "And how exactly did this visitor enter your room, ladies?"

"He just appeared in our room and cuddled Charlie's cat while making loud noises," Vaggie responded, feeling like another headache was coming. "Mind you, he's an idiot."

"What kind of idiot?" Husk asked as he had a feeling he needed to drink.

"The kind of person who is always oblivious and saying our names wrong." The one-eyed girl responded.

The Radio Demon seemed interested in what they were talking about. "And what is the name of the individual?"

Vaggie was about to answer when Charlie responded first. "His name is called, and please don't make fun of his name, Caboose—"

"Hello!"

"AH!" Charlie and Vaggie jumped off the couch upon hearing that childlike voice again. They and everyone else turned to look behind the sofa and saw a blue-armoured individual standing there and staring at the two girls. The others, except for Alastor and Niffty, were surprised to see a stranger in the room without making any noise. Despite this surprise, the Princess of Hell was glad to see him. "Caboose!? There you are! I was starting to get worried that you didn't come back!"

"Oh, yeah... about that..." Caboose immediately spoke as if he was confessing. "You see, Freckles told me he found something outside the hotel after I opened the door. And I went out and found what he was talking about." He put his arms up in the air to celebrate something he had achieved. "NOW, FRECKLES GOT A NEW AND BIGGER BODY NOW! HE CAN USE ANY BATHROOM HE LIKES!"

"This is Caboose?" Angel asked Vaggie, to which she immediately nodded her head.

"Yes, And he's a complete idiot," Vaggie uttered. She was upset that he disrupted her sleep.

However, Niffty seemed to be okay with it. She actually liked this person's attitude. "Don't say that to him! He's just a child!"

"In a man's body wearing blue armour, of course!" Husk pointed out before sipping his alcohol-filled latte.

"Uh, Caboose…" The Blue Idiot turned to look at Charlie, who had the look of curiosity seen on her face. "What do you exactly mean by 'Freckles got a new and bigger body'?"

It dawned on him that he forgot to introduce his pet to them. He cleared his throat to grab their attention. "Where are my manners! I forgot to introduce to you all to my pet Freckles! But I have to tell you to follow me outside, so he won't damage the Hotel."

"Your pet?" Everyone apart from Niffty and Alastor asked before following the blue stranger outside.

-Scene Change-

As they were outside the hotel and now on the pathway, Vaggie rubbed her eyes to keep herself awake. She looked over to Caboose and wondered why he brought all of them outside. "Caboose?! Why the fuck did you bring us out here!? Charlie and I haven't even changed yet!"

"To introduce Freckles to all of you," He said enthusiastically. Just then, he looked at the front and spoke. "Freckles, come boy!" He let out a whistle to call in his pet.

Insert Red vs Blue OST: Manticore Blues

Everyone narrowed their eyes when Caboose had said his pet's name. None of them knew what was about to come. Well, not everyone, to say the least. Alastor could hear faint footsteps coming and looked at Niffty, who was on his left shoulder. "Do you hear that, Niffty?"

"I do!" The small cyclops-like Sinner responded before she gleefully giggled as the footsteps only got close by. "Here it comes!"

This caused the rest of the staff to need clarification on what Niffty and Alastor spoke. As they were about to ask, all felt the ground shaking lightly. "What was that…?" Charlie asked right before looking to where Caboose faced, and her eyes widened at what she saw.

Vaggie and the others had the same reaction to what they saw. She must be imagining things, but her remaining eye wasn't deceiving her. All she could do was to mutter. "Oh, you have got to be FUCKING kidding me!?"

Down to where the gateway was, a tall robot standing over eighteen feet and six inches walked towards them, with each step rambling the hotel's ground. It seemed to be armed with autocannons and missiles on its arms. Everyone could only silently look up to the machine in shock as it stopped behind Caboose.

"EVERYONE, I WOULD LIKE YOU TO MEET FRECKLES!" Caboose shouted in pure excitement before looking up at the robot. "FRECKLES, say hello."

The robot, Freckles, looked down at them and was immediately alerted. "UNKNOWN INDIVIDUALS DETECTED." It readied his weapons. "ENGAGING WITH EXTREME PREJUDICE."

And that caused almost everyone to almost panic. Vaggie already had her spear and was ready to engage the machine. Luckily for her, Caboose immediately spoke to it as if it were a pet. "No! Bad Freckles! Down!"

"YES, CAPTAIN CABOOSE." Freckles said before lowering its weapons.

"Bad Freckles…" Caboose uttered before looking at the others. "So, what do you guys think?"

Red VS Blue OST Ends

"Uh…" Charlie uttered, finding the appropriate way to describe his 'pet', Freckles, without angering it.

"Well, that was one way to introduce your pet to us!" Alastor answered as he walked to him with a smile. "I'm Alastor! It's nice to meet you, Caboose."

"Likewise, Mr. Alexander." Caboose spoke.

Compared to Vaggie, who didn't know how he mispronounced her name, Alastor didn't seem to mind it. Speaking of the person herself, she walked up to Caboose with a look of fury on her face. "Caboose, are you fucking serious right now about that machine being your pet right now!?"

Caboose looked at her and couldn't help but feel his right eye slightly twitching. "What did you just say?"

"I said about your fucking robot being your—" Vaggie repeated.

"No, do not call him that!" Caboose suddenly shouted with anger, catching everyone apart from the Radio Demon and Niffty by surprise. "He is no robot!"

"Uh, WHAT?!" Vaggie couldn't believe what she was hearing. "But he is!"

Seeing the tension between the two forced Charlie to step in between them. "Alright, you. There's no need to fight. Freckles is a wonderful pet."

"Charlie!" Her girlfriend immediately spoke to her. "What are you doing?!"

The princess of Hell turned to her. She immediately whispered, "I'm trying not to get him angry. Yes, he came into our room without knocking, but do you think you're going a bit too far?"

Vaggie wanted to protest Charlie's question. But, when she thought about it, she knew the other girl had brought a valid. She let out a sigh. "Fine. Perhaps I am too hard on him."

Charlie was thankful her girl had considered her words and placed a hand on her left shoulder. "Thank you, Vaggie." She'd realised that she almost forgot to introduce the others to him. She immediately turned to him. "Oh, I forgot to introduce the others to you, Caboose. Aside from me, Vaggie, my girlfriend, and Alastor, this is Angel Dust, one of our guests, Husk, our bartender, and Niffty, our housemaid and cook."

Angel waved at him with a smile. "Nice to meet ya!" Husk didn't say anything and instead drank his alcohol-infused latte.

Niffty immediately approached the blue soldier with a broad smile and a blood-eye shot. "Hi, I'm Niffty! I hope you enjoy yourself!"

Caboose smiled underneath his helmet. "Well, thank you, Niffty! I'll be sure to enjoy it here and make new friends!" He turns to Angel and Husk. "And I cannot wait to be friends with you, Angle and Hush."

"Caboose, It's Angel." Angel corrected him with a friendly tone.

The bartender was irked at how Caboose mispronounced his name and glared at him. "It's Husk, you dumb idiot!"

Now the introduction is over, Caboose wonders what this place is. "Uh, Miss Charlotte? What is this place?"

"This?" Charlie said as she looked around the area. "This is the Hazbin Hotel. A special place where Sinner go and rehabilitate."

"Reha-what now?" Caboose asked.

Seeing how brain-dead he is, Vaggie decides to simply for him. "This is where Sinners come here to rehabilitate to achieve redemption."

Now, the blue idiot was confused by this. "Ah, right. Why would they need redemption?"

Vaggie wanted to yell at him, but luckily for her, Charlie had beaten her before anything wrong could happen. "It's so that every Sinner won't be slaughtered by the annual Extermination event. Every year, these Angels Called Exorcists come from Heaven and kill any Sinners that are left in the open." She said sadly, which ultimately caught the idiot's attention. "We lost so many souls in the recent Extermination, and it breaks my heart to see my people being slaughtered every year. No one has even given them a chance! I can't stand idly by while the place I live is subjected to such violence!" Now, she was filled with determination, which Caboose didn't seem to notice. "That is why I opened this hotel: to allow my people to redeem themselves. Unfortunately, with the next Extermination being in six months, I don't think I'll be able to get a single one at this point."

Caboose went silent upon hearing all of this. He was glad that he was an excellent listener and thought of Charlie's people being killed every year just to cull this place's population. "Well, um, if you are having trouble getting any people in your place within six months…" He suddenly spoke as he looked at the Princess of Hell. "Then why won't you let me be part of your group!?"

Charlie was utterly taken aback by what he said. "What…?!"

"If you're having trouble bringing people here, why won't you let me help you!" Caboose announced. "I am really, really, really, really, really, really, really, really, REALLY good at making friends. Isn't that right, Freckles!?"

"AFFIRMATIVE!" The Mantis Droid responded to his Master.

"See! Even Freckles agrees with me!" Caboose said and looked at the Princess of Hell. "What do you say, Miss Morbinstern?!"

Charlie had a thought in that. She knew that Caboose was a complete stranger to them and how he entered hers and Vaggie's room by simply 'entering through a door' and already making a scene. But he had this determination to aid her in helping sinners on the path to redemption. She let out a smile. "Uh, sure. You can join us, Caboose." She looked at the others. "What do you guys have to say?"

Vaggie put herself in a guard stance and let out a sigh. This isn't what she expected, but as long as Charlie is happy, she will be alright. "Fine. He can join as long as he participates."

Angel placed his hands on his hips and smiled at her question. "If that means a new face, I'm alright with it."

Husk just drank his cup. "He's okay. As long as he stays far from me because of that attitude."

Alastor just placed his hands on top of his microphone stand cane. "I do not mind at all! He could be interesting."

Niffty had the same thought as the Radio Demon. "Yes, I'm fine with him being with us. As long as he remains to be a good boy."

Hearing everyone's words, Charlie turned to face the blue soldier. "Well, you have our word. Welcome to the Hazbin Hotel, Caboose! You are now one of us."

"YES!" Caboose cheered as he looked at his pet, Freckles. "Did you hear that, Freckles?! We are now part of her group! Don't you agree?"

"AFFIRMATIVE!" Freckles spoke.

"I hope this isn't like Tucker's stupid gentlemen's club." He uttered, which caught everyone off guard upon hearing that name. "This is totally going to be so AWESOME AND NEAT!"

Charlie loved his enthusiasm. As much as she wanted to praise him, she felt exhausted. "That's good and all, but…"

"Caboose, we waited for you all night just to come back." Vaggie reminded, now feeling the fatigue from earlier on. "Please give me and Charlie a rest before assigning you."

"Okay!" Caboose spoke with a hint of obliviousness before waving to Vaggie and Charlie as they walked back inside. Seeing them closing the door made him realise something. "Now, how the heck am I supposed to fit Freckles inside?"

"You don't have to worry about that, Caboose," Alastor responded with assurance and a wide smile. "I can help you with that. For now, Welcome to the Hazbin Hotel. I hope you are going to enjoy your stay!"

Preview: FINALLY! I finally joined Has been Hotl! Now, it's time to build trust between them. I got so many they can do. I wonder what they will give me. Hope it's going to be neat and meet new friends?

Yes, Caboose had finally joined the Hazbin Hotel given his oblivious nature. And it seems like Caboose as mispronounced everyone's name except for Niffty. And it looks like Freckles had gotten a new version of the Mantis-Class Droid. Similar to the one he was introduced in Chorus. Though, I have plans for Caboose's pet to get upgraded.

I wonder, since Caboose has given the nickname to them, I wonder what the characters from both Hazbin Hotel and Helluva Boss will nickname him? Please give in your thoughts.

Now, it is official. Hell, get ready to endure Caboose. He's nothing like you have ever encountered before.

BTW, search me up in DeviantArt and look at the poster I made. I have a feeling that there will be many fanarts of Caboose being with Hazbin Hotel and Helluva Boss characters.

I hope this chapter satisfy all of you!? You can criticise this work since I feel like there are many O.O.C moments. But what do you all think of this chapters? And predictions you all wanna make?
