Disclaimer: I don't own anything. RWBY belongs to roosterteeth and Undertale belongs to Toby Fox.
I think most of the chapters of this story will be short, unless I feel like writing a lot, but I doubt that's gonna happen because I'm lazy and I have so many crossover ideas in my head I want to get out. Sorry, but I do hope you enjoy this story.

*BARK, BARK*
"Uuuhhhh, my head," Ruby groaned, slowly raising from the ground into a sitting position. Zwei jumped onto Ruby's lap and licking her face, happy to finally be able to wake her up. Ruby slightly giggled, "Come on, stop it Zwei."
When Zwei finally calmed down enough, Ruby looked around her surroundings and didn't recognize where she was. "Where are we?"
Suddenly, a rush of memories entered her mind. She remembered following two members of the white fang, and then falling down a sinkhole. "Wow. Luckily I fell on these flowers to break my fall, otherwise I could I have been seriously injured," Ruby rose up to a standing position and hummed to herself, "Now how do we get out of here…"
Zwei tilted his head slightly, then sniffed the air. He barked twice and went off in a random direction. "Ooohhh, come on Zwei. This is how we got here in the first place."
Ruby after her dog. She found Zwei growling at a sunflower. "Huh? Why are you growling at this sunflower Zwei?"
"Howdy! I'm Flowey. Flowey the flower," said the sunflower with a smile.
"What the heck!? You can talk," Ruby exclaimed. She was extremely freaked out because she has never seen a flower talk. She knew for a fact that talking flowers did not exist remnant. Hehehe...I must still be dreaming or maybe I am seeing things because I got a concussion from landing on my head.
"Hehe…Why'd you make me introduce myself? It's rude to act like you don't know who I am," Flowey said.
"But I don't even know who you are," Ruby exclaimed exasperatedly.
"Someone ought to teach you proper manners. I guess little old me will have to do. Ready or not, here we go!"
"This is getting too weird for me," Ruby said.
"You see your soul right now if is very weak and small, but it can grow if you get LV. What's LV stand for? Why, LOVE, of course! You want some LOVE, don't you? Don't worry, I'll share some with you," Flowey said with a winking face. Flowey began to throw little white things at Ruby, "Down here, LOVE is little white... 'friendliness pellets.'"
"First off, I'm not worry because I don't need love to grow strong. I have milk," Ruby said crossing her arms with a small pout, "Secondly, I don't really trust you, because Zwei doesn't trust you."
Zwei has been growling at the flower ever since they met him. Ruby kept dodging the 'friendliness pellets' whenever Flowey tried throwing some to her. Flowey was becoming extremely annoyed by this.
"Is this some kind of joke? Are you braindead? RUN. INTO. THE. BULLETS," Flowey said angrily.
"Huh, what did you say," Ruby asked, with a look of suspicion.
"I said run into the 'friendliness pellets'..." Ruby was slowly walking back from where she came. Flowey noticed and his smile faded away. His appearance changed to a sinister one and said, "You know what's going on here, don't you? You just wanted to see me suffer."
Flowey summoned more of the white bullets and they surrounded Ruby. Ruby was freaking out. I don't think this a dream anymore, and it's definitely not some kind of hallucination. She tried to reach for behind her back for Crescent Rose, but her hands touched nothing but air. Shoot. I must have dropped Crescent Rose when I fell down the hole. "Look, I really don't know what's going on, but I just want to get out here. I wasn't trying to offend you or anything. Honestly I don't want any trouble."
"DIE," Flowey said, laughing evilly. The white bullets were closing in on Ruby. Ruby picked up Zwei, and held him closely to her chest, using her body to protect her corgi. She shut her eyes waiting for the bullets to hit her.
However, they never came. Ruby looked up and saw Flowey looked confused. Suddenly he was knocked away by a humanoid goat woman. The goat lady approached Ruby, and bowed down to her eye level. The goat woman helped Ruby up, however, Ruby was skeptical to trust this lady.
"What a terrible creature, torturing such a poor, innocent, youth… Ah, do not be afraid, my child. I am Toriel, caretaker of the Ruins. I pass through this place everyday to see if anyone has fallen down. You are the first human to come here in a long time," Toriel said to calm Ruby's nerves.
"Well, thank you for your help. Um… Do you know how to get out of here," Ruby asked.
"You're welcome, my child and of course I know how to lead you out of here. Come! I will guide you through the catacombs. This way," she said, walking away. Ruby, carrying Zwei in her arms, followed Toriel.
"Welcome to your new home, innocent one. Allow me to educate you in the operations of the Ruins. The catacombs are full of puzzles. One must solve them to move from room to room. Please adjust yourself to the sight of them."
"Okay. No Problem, I'm ready to start figuring this place out," Ruby said. Toriel continued to show Ruby how to solve a couple of puzzles. Of course, Toriel helped her with the first one.
"As a human living in the UNDERGROUND, monsters may attack you. You will need to be prepared for this situation," Toriel told Ruby.
"Wait a second. What do you mean by monsters? Are you saying that I have to fight off Grimm down here, but I don't have Crescent Rose! How am I gonna fight off Grimm," Ruby asked, freaking out at the thought of having to fight off Grimm without her most trusted weapon.
"Worry not, my innocent child. There are no Grimm down here. The monsters in the Underground are different from the creatures of Grimm. When you encounter a monster, you will enter in a fight. While in a fight, strike up a friendly conversation. Stall for time. I will come to resolve the conflict."
"What do you mean 'strike up a friendly conversation'? That's not gonna help me in a fight," Ruby was stated. She was starting to think this lady is crazy.
"Would you at least try it, please my child," Toriel begged, her eyes watery.
"I suppose I can try this once," Ruby sighed, not wanting to see the woman cry.
"Thank you, my child. Now, practice on this dummy," Toriel said with a smile.
Ruby face contorted to one of discomfort, as she walked up to the dummy. "H-hello...um...My name is Ruby... What's your name...um... The weather is nice today, don't you a-agree," Ruby was extremely uncomfortable with this whole situation.
"Good job, my child. The next room awaits," Toriel said with a huge smile. Ruby sighed in relief.
As they were walking, a frog monster appeared out of nowhere. Ruby was freaking and had no idea what to do. Zwei jumped out of her arms and growled at the dog. Luckily Toriel came and scolded the monster. The frog monster hopped away, ashamed.
"This room contains a dangerous puzzle. I wonder if you could solve it," Toriel said to Ruby leading her towards the next puzzle. When they approached the puzzle, Ruby was surprised to see it was a bridge covered in metal spikes.
"Don't worry. Here take my hand." Ruby grabbed Toriel's hand, as she led her through the puzzle safely. Zwei followed closely behind Ruby, walking by her ankles. Once they reached the end of the bridge, Toriel said, "Puzzles seem a little too dangerous now."
After walking for a while, Toriel stopped and turned to Ruby saying, "You have done excellently thus far, my child. However I have a difficult request to ask of you… I would like you to walk to the end of the room by yourself. Forgive me for this." Toriel's face contorted to one of sadness and hesitation, as she said this. Toriel quickly walked away from Ruby. Ruby ran after her, but she tripped over Zwei.
"Oh My Gosh, Zwei! I'm so sorry," Ruby said, hugging her dog. Zwei barked his forgiveness, knowing his owner did not mean to hurt him. She looked up to see if Toriel was anywhere to be seen, but she was not. Ruby set Zwei down and her eyes became slightly watery. Zwei, sensing his owner's distress, grabbed Ruby's cape and began to pull it.
"What are you doing Zwei," Ruby asked. Zwei jumped away and began barking at his owner. He began to walk away, forcing Ruby to follow him. Zwei lead Ruby to a pillar and began to bark at it. Ruby looked at her dog with confusion. She walked towards Zwei and saw a piece of Toriel's dress.
"Toriel is that you," Ruby asked. Toriel walked out of the pillar.
"Greetings, my child. Do not worry, I did not leave you. I was merely behind this pillar the whole time. Thank you for trusting me. However, there was an important reason for this exercise… to test your independence. I must attend to some business, and you must stay alone for a while with your dog. Please remain here. It's dangerous to explore by yourself. I have an idea. I will give you a cell phone. If you have a need for anything, just call. Be good, alright?" Once again Toriel left Ruby alone with Zwei.
However, Ruby didn't feel distress this time. She was confused and slightly frustrated. Ruby thought it best to explore the Ruins with Zwei. I guess it would be alright if I explore this place. I mean it's not like I'm alone or anything. I have Zwei by my side and if anything goes wrong, I can always call Toriel. However, that lady is super weird. I just want to return to beacon with team RWBY. I wonder how team RWBY is going to find me down here? I have no way of communicating with them. I would use my scroll to contact them, but it broke when I landed here.
Ruby was lost in thought, as Zwei walked beside his master. Suddenly, the cell phone Toriel gave Ruby rang. Toriel asked if she left the room and how there was dangerous puzzles ahead, but it was too late since Ruby already left the room.
Ruby entered a room that had a stand with a bowl full of candy. The sign said to take one, but Ruby grabbed a handful, which resulted in the bowl of candy falling down to the floor, and put them in her pocket, walking away from the scene of the crime because she didn't want to be in trouble.
Ruby encountered several monsters during her journey. She decided to compliment them and to engage in a friendly conversation with them, since she didn't have her beloved Crescent Rose and she knew she didn't have enough aura to run away from all of them. The monsters were friendly and were flattered by Ruby's compliment. They even asked if they could pet Zwei. Zwei loved the attention and the monsters were happy. Ruby was just happy she didn't have to fight them.
Zwei helped Ruby solve all the puzzles. Ruby was really grateful that Zwei was here to help get through all these puzzles. While Ruby was walking with Zwei, Toriel would call her several times asking her if she liked cinnamon or butterscotch and other random similar questions. Toriel was acting strange, but Ruby was used to it now. Besides, she was focusing on all the weird things that were occurring to her as she journeyed the catacombs.
For example, Ruby and Zwei encountered a puzzle where they had to move rocks. The first two were easy, but the third one began to talk. It freaked Ruby out. She politely asked the rock to move. The rock was a strange character, calling Ruby pumpkin, and he was being a complete smart ass. The rock annoyed Ruby, but she kept her calm. Eventually the rock complied with her request, allowing Ruby to move forward.
Another example was when they encountered a ghost. When they met the ghost, he was pretending to sleep and it was so obvious since he literally said 'Z' as he lied on the floor. Ruby had a huge sweatdrop from the awkwardness of the moment. She would have walked away, but Zwei jumped on top of the ghost and began to lick his face. He immediately jumped up from shock. He looked like he was going to cry. Ruby felt bad for the sad ghost, so she decided to cheer him. She pulled Zwei away from him and engaged in a friendly conversation. She even tried saying a couple of jokes, mostly bad puns she learned from Yang, and shared the candy she grabbed earlier. She had Zwei do a couple of tricks. Little by little, she began to cheer the ghost up. She found out his name was Napstablook. He even showed her something called the 'dapper look' which was him wearing a top hat. He even became comfortable enough with Zwei to pet the corgi.
Napstablook told Ruby how came to the Ruins often, since nobody comes around there. He mentioned how he was happy to meet a new person who is kind. Ruby blushed at the compliment. Once the ghost realized he was rambling, he blushed, apologized, and got out of her way.
After spending most of her day in the catacombs, she found Toriel.
"Oh my, how did you find me, my child," Toriel asked.
"Well I just followed Zwei," Ruby responded.
"I'm sorry for leaving you alone for so long. It was irresponsible of me to try to surprise you like this. Err… Well I cannot spoil the surprise yet. You must come with me to my home. Come, little one," Toriel cheerfully said.
"Um… Okay," Ruby said, she followed Toriel to her home. Once inside, a sweet aroma filled the cozy, tidy home.
"Surprise! It's a butterscotch-cinnamon pie. I thought we might celebrate your arrival. I want you to have a nice time living here. So I will hold off on snail pie for tonight. Here, I have another surprise for you," Toriel voiced happily, taking Ruby's hand and dragging her towards another room.
"W-wait hold u-up a second…" Ruby stuttered, gently trying to pull her hand away from Toriel's, However, it was too late Toriel brought her to a bedroom and said, "Don't fret, my innocent one. This is it… a room of your own. I hope you like it."
Once Toriel led her inside the bedroom, she hastily walked out, leaving Ruby alone with Zwei. She sat on the bed and turned to Zwei who sat at the foot of the bed. He was softly whining and Ruby looked at her feet sadly muttering to her dog, "I know Zwei. I want to go home too. I appreciate everything Toriel is doing for us, but I can't live here. What should I do, Zwei?"
Zwei curled up to his owner and barked his agreement. Ruby petted her dog in a soothing manner. After a couple of minutes, Zwei was already asleep. It was getting late and Ruby was tired, but also hungry she heard her stomach growl. She sneaked out of the room and went to the kitchen. There was a pie there. Ruby grabbed a slice and ate it quickly. Once she consumed it, she returned to the bedroom and immediately went to sleep. She dreamed of returning to her team and beacon academy.
Fuck, Yang thought as she punched Roman Torchwick. The middle aged man had bruises covering his face and now he sported a broken nose. When team RWBY entered the underground village, chaos immediately began. Yang was the first one at the scene, her eyes red with fury and her body engulfed in flames. She was knocking out members of the White Fang with one punch. She was destroying everything looking for her sister, but she wasn't the only one. Weiss and Blake were disposing of the White Fang quickly and mercilessly, while looking through every crevice for their young leader.
When the girls saw Roman Torchwick, they quickly worked together to beat up the criminal.
"Where's Ruby you creep," Yang shouted. Team WBY thought he was holding Ruby as a hostage.
"Sorry Blondie, but I don't know who or what you are talking about," Torchwick said pointing his gun at Yang. However, he missed when Weiss hit his cane away and Blake kicked his face.
"Liar," Yang shouted punching him in the gut.
They nearly killed the held his bloody figure, holding him in the air but the front of his shirt. She was ready to kill this man with one punch, but Oobleck stepped in and stopped them.
"Stop! You girls are letting your emotions take control of your actions," Oobleck scolded them.
"You better listen to your boss, little girls," Roman said with a smirk, spitting blood on the floor.
"As for you, Mister Torchwick, I suggest you be cooperative, unless you want to die today," Oobleck threatened, pointing his weapon at Torchwick's head. "Now what are you planning to do with all these explosives."
"Huh..." the three girls said simultaneously. Finally, they realized that there was a train full of explosives, not noticing it before because they were occupied with trying to find Ruby.
"Well...I would love to share my great master plan, but wouldn't that be cliche," Torchwick snidely replied to Oobleck's question, "Besides I wouldn't want to spoil the...surprise." Torchwick began to snicker, until Yang knocked him out with one punch.
"Miss Xiao Long," Oobleck reprimanded.
"Sorry Professor, but that guy really ticked me off," Yang responded.
"Your anger will be your downfall one day. You will discuss your punishment later for disobeying orders, but right now we have take Mister Torchwick to Beacon Academy for interrogation."
"But Professor, what about Ruby," Weiss and Yang said together.
"Professor Oobleck is right. We need to interrogate Torchwick and the White Fang to find out what they are up to. This is our number one priority. It is why we came here in the first place," Blake told her comrades.
"What the fuck Blake," Yang exclaimed, grabbing the front of her partner's shirt.
"Miss Xiao Long! If you can't control yourself I will have to put you in probation, and you will be unable to search for your search for your sister," Oobleck warned her. Yang pushed Blake away and stomped away. Weiss looked disappointed at Blake, before running after Yang. Oobleck placed a comforting hand on Blake's shoulder, before walking away to call for assistance.
