Stanley was in the hospital, and Wendy just gave birth to triplets to the surprise of everyone, having twins was a tradition in the Pines family but Triplets? That's another story.
Currently, The infant boy which got named Tyrone was in Dipper's hands and the father looked like he was going to faint any moment, with the girl named Anna in Mabel's hand who was ecstatic beyond words and the other named Avalon in the hands of the sat down Wendy on the bed.
"Yo Stan! Come and say hi to your Great-Nephew's daughter!" the mother urged her Grunkle-in-law to come, once Ley hesitantly got the baby something happened which made his pupils grow big.
"Guug-gaa." the babe uttered, causing a storm of wholesomeness to take over Stanley looking at her with almost sparky eyes, for minutes he kept the baby in his hands as if he was afraid she would fall from his hands and crack to a million pieces like a glass jar.
"Stanley? It's my time now." His brother stepped in and gestured to him to give him the baby.
"NO!" he moved her to his chest in a protective hug "get your own infant to corrupt!" he hissed.
"It's my time now Stanley! Fair and square!" Ford pressured his brother to give him the baby.
"Catch me if you can, nerd!" Stanley ran with the baby from the running Stanford, and just like that the history rhymes itself with the running Stanley with a baby away from another elder Pines just like when he first time saw Dipper and Mabel when they were infants and didn't let Sherman to hold them because he was greedy as the wife and husband rolled their eyes with the aunt giggled at seeing the Grunkles making a fool out of themselves.
Years later…
'What was I thinking?' The same thought came into Stan and Ford's minds, maybe agreeing to babysit Dipper and Mabel's triplets wasn't a very good idea, don't get me wrong both elder twins loved the young Triplets; however, they as they learned can be a handful.
"Look Grunkle! It's my new pet!" Avalon said cheerfully with a collared angry Mongolian sandworm that was on her head and trying to swallow her with half of her head from up.
Stanford nearly suffered a heart attack as he looked in horror, nearly fulfilling Bil's prophecy about his cause of death.
*BOOOOOOOM!*
"AAAAAAAAAH!" Stan wakes up from his bed screaming.
"Happy April's fools old dinosaur! Have you scammed someone today?" Anna with a bugle greeted a woke-up Stanley.
"I'm both annoyed and proud at the same time," he said, annoyed.
"HAHAHAHAHAHAHA!" Tyron in a white coat and black experiment goggles laughed maniacally because he used necromancy and forbidden science to bring the life to a dead frog with metallic antennas, patched body parts of various animals such as a chicken leg for its right leg, a crab arm for its left arm and bat wings and it currently was flying all over the living room. "I HAVE CREATED LIFE!".
Older Pines twins were using a chair and a table to shield themselves from the rabid bat frog that was attacking them to give them vampire-zombies rabies.
Is it any wonder every time Wendy and Dipper weren't in the house they hired or convinced someone to babysit the kids of their chaotic nature? The Stan twins came to this conclusion as they tried to find the young triplets in the garden.
"I swear these sassy kids will be the end of us." Ford's twin grumbled.
"I wonder if this is karmic justice for us Pines being a bunch of sassy trouble-seekers." Stan's twin wondered.
"Our family does have a trend of bringing trouble seekers, but these knuckleheads are even more of a rascal than any member of the Pines family in the history of our family tree!" The conman uttered in exasperation.
"Perhaps this is a genetic quirk which is only amplified thanks to the addition of the Corduroy genes." The scientist hypothesized as he looked over a bush for the hidden rascals.
"Over here!" The duo looked over and saw smug girls up in a tree. "Oh, you little brats are soooo grounded for making us try to find you for an hour!" Ley pointed in accusation toward them who didn't look even a bit intimidated.
"Stanley, wait, there are only the girls, where's Tyrone?" Stanley's brother was puzzled, before any of them had the chance to register the girls leaped from the top of the tree on the ground and started racing.
"Catch us if you can, old man!" a running Ava taunted.
"Don't sass me young lady!" a chasing con artist responded to the sassy girl.
While the hustler was pursuing the puffed-haired child, the six-fingered man ran after the other Pines kid who pranced into a bush, The man of science now was left to solve the puzzle which is finding his target who kept showing her head out of the plant and goad him in grabbing him.
"Here!" from Left.
"Here!" from Right.
"Here!" from Middle.
"Here!" Right.
Annable kept popping her head from the bush and disappeared repeatedly with Ford trying to snatch her each time "Oh in the name of-" he was becoming tired so he just jumped into the bush only for the redhead girl to then jump out of the bush and ran away.
"Too slow!"
The multiversal traveler sighs deeply and comes out of the bush to follow her.
While Ford was busy running toward the pink shirt kid, Stan trying to look for the goggled girl with a withered hat, he stumbled upon a shadow behind a tree which prompted him to grin. "Oh, I wonder where that little twerp went? Maybe I should check the basement and- AHA!" He quickly moved behind the tree only to see a dummy made in a crude fashion of her with a note that said "'I Outscammed ya!? No one out-scammed the scamp-scap-scar…!
"It's scammer." Ford corrected him as he was chasing.
"No one asked you for literature lessons!" He takes the note and violently smashes it in his fist in outrage and pride over the fact that he got out conned by the Pines kid.
"Nice sprinting, I just got warmed up!" Annable blew a raspberry at the now tired elder who kept chasing her circles. "My *breath* body *breaths* is not *breath* what it used to be…" the panting dimension hopper vocalized, years haven't been kind to the elder Pines much on their body and stamina even though they used paranormal means to extent their lives.
"We just got started!" Avalon came and joined her partner in crime and went inside the house.
As the author of the journals was busy collecting himself, his sibling came and joined in. "Not any better chances huh?" he questioned breathing, "Oh this time they are not going to fool us!"- he clapped his hands together -"Come Poindexter! they are now inside the house, we will find them, come!" he gestured his twin to follow him to the inside of the home, there were no lights and everything was suspiciously dark.
"Now where is the switch to turn on the-" without any warning, every light in the house got lit up.
"SURPRISE!" The entire set of triplets greeted the startled Old men with glitters flying all over.
"What in tarnation…" once the ex-Mr Mystery's eyes adjusted and left his hands away from his face, he saw a big sign from the roof which said 'SURPRISE!' in numerous colors with the trio in the living room welcoming him.
"What's this now?" He looked confused.
"Isn't it obvious? It's a surprise! Otherwise, why do you think we kept trying to keep you out of the house?" Ty informed them.
"But, our birthday is not today," Fordsy noted.
"So what? That doesn't mean we can't do something nice for our favorite Great uncles!" Ava counteracted his point.
"Here, we made this together!" Anna responded and then gave them a present warped in red colors and white dolts with a golden ribbon. Stan and Ford at first looked suspicious, thinking this is just another prank until they opened the cover and found out that it was genuine, what they saw was a brown diary with glitters and labels written 'Stanley and Stanford Pines: Our Heroes' when they see inside of it they found images and pictures of them but younger from when they were kids, their older versions spending time with Mabel and Dipper across the years from when they were 12 years old till their graduation and their marriage to their respective spouses and finally it was them hanging out with the triplets and then a series of blankets which said 'Make new memories with us' in first of all blanket papers , the nostalgic hit the Old Pines hard and were touched by this gift with Stan, in particular, was in the verge of crying.
"Are you crying?" Tyrone teased.
"NO! I'm allergic to all your sasses!" Stanley immediately wiped his tears and shouted out at the chuckling kid, Ford couldn't help but smile 'These kids are going to grow into fine individuals.' he thought warmly.
