It's now been 3 days since team RWBY found the puffball and they were having trouble trying to keep him under control. They discovered he had an inhuman appetite and found it extremely difficult to keep it satisfied. Right when they were at their breaking point, they were sweep away on another mission, but unknown to them Kirby had followed. They're in the forest fighting a pack of Grimm and quickly losing. When Kirby saw Ruby hit the ground, he rushed in and knocks back an attacking Grimm. The rest of the team converge on Ruby and watch as Kirby sucked up some fire Weiss had made will fighting the Grimm and then, to the team's surprise, Fire Kirby was standing in front of them and single-handedly fought and defeated the pack of Grimm. When the fight was over, Kirby returned to normal and ran to team RWBY with a smile on his face, while Ruby was amazed, Weiss, Blake, and Yang were baffled at they witnessed.

Back at the dorm, the team was rather fascinated with Kirby's newfound ability to copy other powers. Ruby, as usual, baby talks him about it while Yang goes off to get a snack. Blake and Weiss debate if Kirby's copying ability should be tested. Blake offers that if they should, Weiss would have to use some of her own dust for it. Weiss on the other hand doesn't want to waste all of her dust as it's needed for missions. Ruby is still stuck on how they can feed Kirby without going into debt. Fortunately for her, Yang comes back feeling down because she could only find tomatoes. Kirby looks excited and jumps for Yang to give him some. This gives the team an idea on how to train him.

In the training room, RWBY has come up with a plan to test Kirby's abilities.

"Okay Kirby. If you show us how you fight, we'll give you a treat okay?" said Yang.

Kirby nods in agreement.

"Okay Weiss, just like we planned. Use your ice dust on Kirby." said Ruby.

"Fine but you owe me a new vial." complained Weiss.

Weiss loaded her sword and creates a glyph to shoot ice at Kirby.

Kirby inhales it and transforms into Ice Kirby.

Weiss and Kirby begin to spar. As the fight progresses, Kirby proves to have the upper hand against Weiss until he freezes her in a block of ice. Yang rewards Kirby with a slice of tomato. Kirby rejects his Ice ability for Blake to offer a fragment of her Gambol Shroud for Kirby to inhale, ergo transforming into Ninja Kirby. Their sparring was cut short when Blake proved a formidable opponent against him. Yang congratulated him anyway for having an undetermined supply of ninja stars. Kirby gave back the fragment of Blake's Shroud and was greeted by a surprised "Thank you" from Blake. Ruby took into account how Kirby can expel his copied powers out of his body and offers Yang to spar next. Yang is worried since she needs both gauntlets to fight. Weiss, reluctantly, offers more dust just to get Yang's part of the sparring out of the way. The dust in question is black, which Kirby inhales to become Bomb Kirby.

"...Okay. I don't know how that works. But..." said Weiss.

Kirby begins throwing bombs at Yang, which she easily deflects back by punching them away before exploding. Kirby had to come closer and land a bomb on Yang's head for any desired effect. Yang tried to get it off without success.

"Wah! Get it off! Get it off!" said Yang.

"I got ya, big sis." Ruby said as she went to help but was too late.

*BANG!*

The bomb exploded, leaving Yang with a face and upper torso covered in ash.

"I think we're done here." said Blake.

Kirby jumps on Yang's leg for more tomatoes.

"Okay, buddy. You've earned it." she said as she gave Kirby the rest of the tomatoes.

Back at the dormitory, Team RWBY regroups to assess their training with Kirby while the pink puffball enjoys some snuggling from Ruby.

"Hmmm well, that was interesting." said Weiss.

"More like embarrassing. How can something so small and cute be such an amazing fighter?!" yelled Yang.

"I don't know, Yang but a more important question is what do we do when Professor Ozpin finds out about Kirby?" pondered Blake.

All the girls had worried looks about what would happen to their new friend if he was discovered.

"We can't let that happen. Kirby's our friend and we can't just abandon him after he saved us." said Ruby.

Weiss sighs and says, "I guess we'll just have to hide him for as long as we can and hope for the best."

"Weiss is right, we just have to hide him but for now, let's get some sleep." said Blake.

Team RWBY change into their pajamas and got in their beds. After they got in their beds, everyone notices Kirby head for the window.

"Whoa, little guy!" said Yang as she grabs Kirby. "It looks like someone's going to have to hold him for the night."

RBY said in less than 3 seconds, "Weiss."

"Why me?!" complained Weiss.

"Because you were the first one to lost to him." Yang said as she hands Kirby to Weiss.

"Fine but Ruby holds him tomorrow." said Weiss as she takes Kirby.

Kirby yawns and snuggles up to Weiss.

Weiss blushes from this and looks up to see her team watching, "What are you guys looking at?!" She turns to face the wall and snuggles into Kirby then falls asleep with a smile.

The next day at the cafeteria, Team RWBY are sitting together having breakfast and Ruby is hiding Kirby in her cape draped around her front.

"I couldn't find any tomatoes in the salad bar. Hope pink puff likes cantaloupe." said Yang as she handed a piece to Ruby.

Ruby takes a piece of the melon ad hands it to Kirby under her cape, who snacks on it with glee..

"I think he likes it." she said.

"Phew!" Yang replied with relief.

Blake was pondering the current situation before saying, "...How are you hiding him in there?"

Ruby contemplated on this before answering, "I have no idea." as she giggled.

Team JNPR then walks up to their table with their own food.

"Hi, girls. Are any seats taken?" asked Jaune.

Yang answered, "Nah, go ahead, guys."

"Thanks." said Jaune.

Team JNPR took their seats on the other side of the table with Kirby noticing Nora's stack of pancakes and struggles to get out of Ruby's cape.

"Huh? No. Not now. Stop it." said Ruby as she tried to stop him.

Jaune sees this and asks, "Are you okay, Ruby?"

"Oh, yes. Yes. I'm good." she said as she slaps the bump on her coat that is Kirby. "Calm down."

Nora sees this and gasps, "Ruby, are you gonna have a-"

"No! No. It's not like that!" Team RWBY said.

Nora was disappointed and said, "Oh."

"Can we have a moment, please?" Weiss said as Team RWBY got up and move to a nearby, clear hallway and let Kirby out of Ruby's cape.

"Kirby, please can you calm down?" begged Ruby.

Weiss then said harshly, "Seriously, you need to calm down. You were almost seen, do you want to be taken?"

Kirby then looks sad and bows his head in shame. Small tears threaten to fall.

"Weiss look what you did!" complained Yang.

"Someone do something before he calls attention to himself!" said Blake as she looks both ways for anyone.

Weiss signs and gives Kirby a hug, "Now now, it's alright. It's not your fault you're hungry."

Kirby nuzzles into her chest as a sign of accepting the apology.

"That was close, now can someone please take him back to the dorm? Breakfast is almost over." Ruby said.

"I'll do it, come on. Let's go Kirby." Blake said as she held out her arms.

Kirby jumps into Blake's arms as they walk away.

"You know it's only a matter of time before someone finds out about Kirby, right?" said Yang.

Ruby sighs and says, "I know but what are we supposed to do? Give him to the military or let him roam? Who know who he could run into?"

"Then what? We can't hide him forever." stated Weiss.

"But what choice do we have? He's pretty strong; someone could use him as a weapon." said Ruby.

Yang sighs and says, "Good point."

Back to Blake, she had made it back to the dorm with Kirby undetected.

Blake places Kirby on the bed and says, "Okay, Kirby, stay here and we'll be back after classes today." She then Turns around to walk away until Kirby stops her.

Kirby whines and pulls her hand, saying, "Poyo: translated to: Don't go."

"Kirby let go, I have to get to class." says Blake as she turns and sees Kirby's puppy eyes.

"Poyo: I don't want you to go, Blake!" he said.

Blake then back turns with a sad face and says, "Sorry but I have to go." She then Pushes Kirby away.

Kirby sits down and starts to cry.

Blake hears a sniffle and comes up to Kirby to hugs him, "Don't cry, it's just for a little while." She then whips away his tears and kisses his forehead. "Tell you what, we'll comeback at lunch and bring you something to eat. So don't worry. How about I lull you to sleep? That'll make the time go by faster." she said.

"Poyo: Yay!" said Kirby.

Blake the picks up Kirby in her arms and rocks him. "hush little baby, don't say a word. Momma's gonna by you a mockingbird. And if that mockingbird don't sing, momma's gonna by you a diamond ring." she sang.

Kirby then falls asleep.

Blake smiles to this and says, "He's so cute when he falls asleep."

Meanwhile with Team JNPR.

"Do you guys think Ruby, Weiss, Blake, and Yang are hiding something?" asked Jaune.

"Yeah, they did. Maybe we should check it out." said Ren.

"Yeah, what if it's something super cool or something super dangerous?! We have to check it out!" Nora excitingly proposed.

"Do you think it's our business to know? Maybe they have a reason, like it's a pet they aren't allowed to keep here but they wanted to get it breakfast." Pyrrha suggested.

"Maybe but still we should check it out." countered Jaune.

Pyrrha sighs and admits, "Okay. When do you think we should sneak into their room?"

"How about after Port's class? We have it after lunch everyone seems to be sleepy after his period long stories." Ren offers.

"Good point, Ren. So we hit their dorm after class and see what they're hiding." said Jaune.

Pyrrha then said, "I still think we shouldn't but it looks like the team's decided."

"YEAH! Team RWBY's secret will be revealed!" shouted Nora.

Pyrrha then jumps from her seat and covers Nora's mouth, "Not so loud, Nora! If we're going to find out their secret, we shouldn't announce to anyone what we're going to do!" she said.

"Come on let's get to class." Jaune said as Team JNPR heads for Ports' class.

One class period of boring stories later, Team RWBY walking out of class half asleep.

"That was brutal! How can he talk that long without breathing?" said Ruby.

Weiss sighs and comments, "I don't know, maybe an old breathing technique?"

Meanwhile, JNPR rushed out of class and now stand in front of RWBY's dorm.

"Alright, who can pick a lock?" asked Jaune.

"Let me give it a try." said Pyrrha as she comes to the front of the door and using her semblance to unlock it. "And we're in."

Nora then hums Mission Impossible theme.

"Nora, what are you doing?" asked Ren.

"Just humming a song that fits what we're doing right now." said Nora

"Knock it off, Nora. This is serious!" Jaune said as he opens door and hears light snoring. "I hear something. I hear snoring?"

He then opens the door completely and JNPR is shocked to see the little pink ball with numbs and big feet sleeping on Blake's bed.

Ren was wide eyed in surprised and asked, "What on remnant is that?"

"I don't know but," Pyrrha said as she pauses and starts to cheeky smile. "it's adorable!"

Nora grins like there's no tomorrow and says, "He's the cutest thing I have ever seen!" She then rushes to pat his head but is stop by Jaune.

"Don't touch it! You'll wake it up." he said.

Nora huffs and moves her hand back, "Fine!" she said.

Ren then moves forward and gets a closes look, saying, "So, this what Ruby was hiding at breakfast."

Unaware to JNPR, team RWBY was approaching with various snacks and drinks.

Ruby was carrying 2 boxes of snack cakes. "I hope Kirby is alright, he's been alone in the dorm room since breakfast. What if he got out?" she said.

Blake was carrying some 2 liter sodas. "Don't worry, Ruby. I sung him to sleep before I left for class, he should still be sleeping." she proclaimed.

Yang, with a bunch of various fruits in her arms, says, "Yeah, Ruby, you're worrying too much. He's fine."

Weiss was carrying a large box of Pumpkin Pete brand cookie sandwiches and says, "Let's just get these snacks to him and get to class before- did you leave the door open, Blake?"

RWBY then turns in shock to see their door wide open and rush to in with snack still in hand and shouts, "KIRBY!"

Team JNPR turns to see Team RWBY at the door.

Jaune smiles nervously and says, "Hey, girls. Nice day we're having."

"Why didn't you tell me you were hiding something so adorable?!" said Nora.

"For the record, this wasn't my idea." said a quickly defending Pyrrha.

"Look, we can explain everything." said Ren as he tried to keep the calm.

RWBY is shocked to see JNPR in their dorm. Ruby places the cakes on the table and goes to close the door.

She turns around and breaths in and out, "Okay, Jaune, quick question. Ahem, WHAT ARE YOU GUYS DOING HERE?!" said Ruby.

JNPR jumps back from the shock with Nora jumping in Ren's arms and Jaune jumping in Pyrrha's arms.

Kirby stirs and blinks awake, turning to see RWBY, "Poyo!: You're back!" he says as he jumps of the bed and runs to hug Ruby by her legs.

Jaune was still in fear, "We were curious to what you were hiding at breakfast so after class, we came to investigate." he says as he jumps out of Pyrrha's arms.

"Yeah! said Nora as she hops out of Ren's arms. "But we didn't expect to see such a cute little thing!" She then points to Kirby.

Yang then places fruit on the table, "His name is Kirby. And, you guys aren't gonna say anything about him to anyone else, right?!" she threatened as she cracked her knuckles.
