Frisk gave a contented sigh, leaning back in his chair with a small box of popcorn in his hand. The atmosphere was relaxed, as it always was in The Great Papyrus, the skeleton's bar being one of the most peaceful establishments in the city, as well as the cleanest. Especially since Papyrus had begun hiring Woshuas to help him clean the place. there were only a few other occupants, most of them seated at various other tables around the room, while the one or two sat at the bar itself, where Papyrus was busy cleaning glasses.
"I'm surprised Alphys and Undyne aren't here yet," Asgore rumbled from his place next to Frisk, dressed comfortably in a pink sweater and slacks. He looked over to his wife. "Do you think they're alright?"
"I wouldn't worry about it, Asgore," Sans spoke up from the other side of the table. "Undyne probably just broke her keys trying to start the car again. She should really look at getting some stronger ones, the normal keys aren't very… E-fish-ent for her."
There was a chorus of chortles from around the table, though Chara's voice groaned in Frisk's head.
You're all so terrible…
"No trout you are correct." Toriel quipped, earning another chuckle.
"Hold up!" Someone cried from across the room, and the table turned to see Papyrus striding around the bar to plant himself in front of the table, his hands on his hipbones as he glared at them.
"Something fishy's going on here, Why do I get the feeling you're telling… why is everyone laughing?"
"Aw man Paps." Sans gasped, hunched over and trying to catch his breath between guffaws as the occupants of the table howled in laughter. "That was brutal!"
The skeleton's skull morphed into a confused expression.
"We were… telling…" Frisk struggled to say in between gasps for breath as he clutched at his sides. "Fish puns." He finally managed.
The confused expression deepened for a moment, then it was replaced with a horrified look, much to the furthered amusement of his friends.
"Oh gods…" He muttered, putting his face in his hands and slumping into a chair that Sans barely managed to pull out for him. "Sans… what have you done to me?"
The laughter gradually subsided and the smaller skeleton patted his brother on the back.
"I'm very proud of you Paps," He stated. "You've taken your first step into the art of the pun master. One day you'll be just like me."
"This is how the world ends, isn't it?" The skeleton groaned. "I feel like I need to wash out my mouth with soap now."
There was a loud clattering sound, and the group turned, barring Papyrus who still had his head in his hands. Standing in the doorway, with the old-Western style saloon doors closing behind her, was Undyne, the woman holding Alphys protectively in her arms.
The fish-warrior had a massive grin on her face and she sprinted towards the table somehow managing not to knock anyone or anything else over in her charge.
"Sup, nerds!" She hollered, placing Alphys down gently into a chair and taking a seat beside her wife.
"S-sorry we're late…" Alphys mumbled, though she was smiling too.
"Hey, it's your loss." Frisk grinned, taking a handful of popcorn and inspecting it for a moment. "You missed Papyrus telling a-"
"Nothing!" The skeleton interrupted, his head raised and his arms flailing about in denial. "I said nothing! Not a single accidental, horrible pun has ever entered my boney tones! It certainly did not happen just a few moments before you arrived!"
"Huh?" Undyne asked in confusion, staring around the table at the grinning occupants.
"Well!" The tall skeleton proclaimed, sweat beading on his skull as he stood up to his full height. "I should get back to work! Call me if you need any more drinks!" And with that, he tore off, sprinting back to the safety of his bar.
Undyne scratched the base of her ponytail with a clawed hand.
"What was that all about?"
"Our skeletal friend may have accidentally entered into our pun war," Asgore explained. "He does seem to be taking it well, considering."
"Hah! No wonder he left so fast!" Undyne crowed. "I bet the look on his face was priceless!"
Frisk opened his mouth to speak, but was distracted by the gleaming metal armband that encircled the fish-woman's left arm, just below the elbow. A thick tube ran from it, going down her forearm and sinking into her flesh just above the wrist.
"Hey, is that your new Determination recycler?" The boy asked. Undyne grinned in response.
"Hell yeah! Nice, isn't it? Alphys finally finished the last upgrades on it, so it should be good to go from now on!"
"Y-yeah." Alphys put in. "It should be almost invulnerable to both physical and magical damage, and it has six separate backup routers for in case anything goes wrong. And if something does happen, w-we should have a decent window of warning before anything actually shuts down."
"Sounds like you thought of everything," Toriel smiled,
Of course she did. Chara muttered. If that thing stops working… Undyne's as good as dead.
Well, aren't you just a little ray of sunshine. Frisk replied sarcastically.
Not knowing she was being talked about in the relative privacy of Frisk's mind, the fish warrior raised her arm to show off the recycler, her golden wedding ring gleaming dully in the light.
"And this is thing is way less clunky than the old one too! I can finally wear long sleeves again!"
"I suppose you'll be wearing your leather jackets more often then?" Asgore questioned.
"You know it!"
"So, why'd you call us here in the first place?" Sans asked. "Not that I ever mind harassing Paps, but you guys sounded pretty excited when you called me here."
Frisk nodded eagerly, leaning forward, not noticing that he was spilling some of his snack on the ground.
"Yeah! What gives, guys?"
The two women looked at each other, then Undyne grinned, pounding the table in excitement.
"We're pregnant!"
"T-technically, I'm pregnant." Alphys corrected, looking down and nervously fiddling with her wedding ring, though her smile widened to the point where it rivaled Undyne's own.
"The point is, we're having a baby!" Undyne yelled, not caring as several of the other patrons turned to look at the group.
"That's wonderful!" Toriel exclaimed, clapping her hands together in delight. "I'm so happy for you two!"
"How far along are you?" Asgore asked, smiling widely.
"Two months, about." The reptile murmured. "We only found out today… I was feeling some fluctuations in my magic system… so I checked and...there was a second magical signature." Her voice was filled with warmth and awe, as well as trace amounts of disbelief.
"That's amazing!" Frisk cheered. "Good thing I helped you guys get together back in the Underground huh?"
"You know it! C'mere, punk! Undyne reached across the thankfully barren table, and grabbed at the boy before he could protest, pulling him into her lap and giving him an affectionate noogie. Having not anticipated this move, Frisk's grip on his popcorn slipped, sending both box and kernels everywhere.
"Hey, I was eating that!" Frisk laughed, struggling in vain to get out of the warrior's grasp. "I'm not a little kid anymore, Undyne, you can't just pull me over the table!"
"Hah! Compared to us, you might as well be!" The warrior crowed, not releasing her grip on her victim.
"Aw man, I feel sorry for your kid now." The boy joked. "Bet they're gonna have to endure a lot of this kind of thing…"
"He'll have a lot of Undyne in the mix." The Alphys said fondly, adjusting her lab coat. "I-I think he'll be able to handle it."
"He?" Frisk questioned, momentarily halting his struggle. "You know that already?"
"Pregnancy works differently for Monsters," Toriel explained. "Since we are mostly made of magic, and can detect the magical signatures of other Monsters, it is not difficult to learn many things about our children, even early on in the pregnancy."
"Huh," Frisk muttered. "How did I not know that?"
Because you fell asleep in the sex ed class, Chara informed him. They do things on Monsters too now you know.
Aw, man, I didn't know that! I thought it was just gonna be a bunch of stuff I already knew! What did they talk about?
Not my job to get your work done for you, remember? The girl said smugly, quoting Toriel's words from a few weeks ago.
"Anyway!" Undyne enthused, finally relinquishing her grasp on the boy, allowing him to quickly scuttle back to his seat. "We called you here to celebrate, and that's what we're gonna do! Papyrus!" The last word was a yell, quickly summoning the tall skeleton over. "We're gonna need some drinks, buddy! On me!"
"Of course! Drinks are our specialty at The Great Papyrus!"
"Uhh… You only serve drinks, Pap," Sans noted.
"That doesn't make me wrong!"
You know, I think it's a good thing that Alphys is the one pregnant, and not Undyne, Chara mused while the adults began asking for drinks.
Why's that?
Can you imagine Undyne being hormonally imbalanced due to pregnancy?
Frisk's eyes widened in shock.
Oh. Then his brow furrowed narrowed. Hey wait a sec, does that even affect Monsters the same? Do they even have enough of a physical form for that to be a problem?
You'd know if you stayed awake in class, Chara replied in a sing-song voice, much to her brother's annoyance.
Why are you so mean to me? Frisk groaned.
Don't act like you don't deserve it. You remember the candy shop.
Are you still hung up about that?
We could have had chocolate. Instead, we had that nauseatingly sweet… whatever it was. I felt sick for hours afterwards.
Hey, that stuff was good! Frisk protested.
"Frisk?" Toriel asked, snapping the boy out of his reverie. He blinked a couple times in response.
"Sorry, Mom," He mumbled. "Just uh… talking with Chara."
"Heh. And we were just talking about her." Sans grinned.
"I asked what Chara thought about all this." Toriel explained.
Well sis? You wanna take over for this one?
Frisk closed brown eyes. Chara opened red ones.
"I think we're all gonna have to tread very carefully." She said, leaning forward. "Let it sink in for a minute… we're going to have a miniature Undyne running around in a few months. I suggest you all enjoy the peace and quiet while you can."
The Monsters at the table looked at each other.
"Oh dear…" Toriel said, only half-joking. "I hadn't thought of that…"
