Some story I found online, I will extend it

Kikoriki in Pibby (Extended version by me, original by A-Pink-Bunny)
It was a peaceful day in the world of Chamomile Valley
Everyone was minding their own business and going on with their days when a sudden rumble took place
The world shook as everyone looked around for the possible cause of it
In one area, Krash the Rabbit was going on with his daily shenanigans with his best friend, Chiko the Hedgehog, when they noticed the ground shaking
They both looked around confused, wondering what was going on, when suddenly, black ooze covered in glitches appeared and slowly moved towards the two
Krash, being naïve and curious, went to get a closer look, when he accidentally touched it and the effects started to happen
Krash suddenly screamed and tried to escape, but he was sucked in and turned into a lifeless glitched creature
He slowly went towards Chiko, but he panicked and ran away towards the nearest source of help
Chiko ran until he spotted his other friend, Wally the Ram, sitting outside and writing his poems
Chiko approached him and tried to explain what happened, but it only left Wally confused
Then, Chiko turned to see Krash quickly heading towards them, so he quickly grabs Wally and runs towards his home
They make it to the front door, but before they could head inside, Krash pounces on Wally and passes the corruption onto him
They then surround Chiko as they slowly close in on him
Meanwhile, more of the glitchy ooze appear in the land and it slowly makes its way towards the rest of the characters
Just a small distance away sat the home of Barry the Bear, where he was working on his garden like every other day
The ground shook again for a bit and it got Barry concerned
Then, his best friend, Dokko the Moose, walked by and greeted the bear, before raising the question of the strange “mini earthquakes”
Barry told him that he noticed them but wasn’t sure on what was causing them
Dokko started theorizing on what it could be based on some research he did earlier in the day when they first started, and went on about certain things that Barry barely understood due to the big words Dokko used
Suddenly, Dokko gets cut off with the distant sound of Chiko screaming in fear
The two looked towards where it came from and waited for something to happen, most possibly an explosion from what it’s typically
But when nothing happened and Dokko was about to continue his explanation, the corrupted ooze appeared and caught Barry’s eye
He froze in his tracks and stared at the ooze until Dokko took notice and turned around
Krash the the other two chased them, as the world got covered in more
corrupted ooze
The sky was turning dark and the earth began to shake more
Barry was still rushing through the land, looking for a place to hide, when he suddenly trips and falls, dropping Dokko and his shovel
Dokko crashed onto the ground and quickly got up to help his friend out
Barry gets up and dusts himself off, but Krash and co quickly caught up to them
The two panic and try to figure out a way to escape when a portal opens in-front of them
Krash and co both get distracted by it, giving Dokko and Barry a chance on hiding behind a nearby tree, and out comes a different character that they never seen before
She was blue, had long purple hair, and an eyepatch
She held a sword and fended off the corrupted trio
Dokko and Barry watched from behind the tree as she fought them off, confused on what was going on
She suddenly spoke to them and told them to quickly get away to a safe spot while she fought the corrupted characters off
They obeyed and quickly ran off
The two ran for a while and stopped near a forest to catch their breath
Suddenly, the blue character ran to them and quickly asked if they were ok
Dokko replied first and then asked what was going on
She looked back towards where she came from and quickly explained that, from what she gathered, some form of corruption was affecting cartoons and that she had been fighting them off ever since it started
The two glanced at each-other concerned
She then introduced herself and talked about where she came from before the corruption happened before going quiet
Dokko noticed and nervously asked if that was the reason for her eyepatch
She nodded and sighs
Barry noticed that she was covered in a red liquid and asked what it was Pibby froze and nervously told him that it’s best he didn’t know
The ground suddenly shook again and Pibby quickly looked towards the
horizon
A wave of ooze was slowly approaching them, so she told them that they had to leave immediately
Before she could open a portal to escape the world, Krash lunges in- front of them and nearly hits Pibby
Dokko and Barry both jump back and Pibby quickly tells them to run
The three ran as Krash crawls after them, his leg being injured earlier from a stab wound
They make their way into the forest and ran in various directions to shake him off
Soon they hid behind a tree and Pibby quietly peeks to check if they lost Krash
Dokko and Barry catch their breath and sit by a tree to wait things out
After a few minutes of waiting, Pibby declared that they were safe, but she told them that because of the land’s current state, they couldn’t hide out here any longer, reminding the two about her earlier statement about leaving the valley to a safer place
Barry quickly asked about the others and if they could go grab them before leaving
Dokko was about to reply to his question when Pibby replied to him first
She calmly told him in the nicest way possible that as much as she wanted to go back and gather other possible survivors, she didn’t want to risk running into any more of those corrupted monsters, and as much as she hated to say or think this, it’s possible it’s already too late to save the others now
Barry understood and took off his hat in respect of his fallen friends, Dokko comforting him as well
Pibby sighed and peeked one last time to ensure they were clear to leave the Riki universe
She turned and opened a portal to travel to a safe place for the two to
hide
They watched in awe before Pibby turned to them and signaled them to step through
Dokko and Barry glance at each other and stick close as they walk through the portal, Pibby following behind them, taking one final glance at the world
The dark substance continue to eat up everything in the land and she could see glimpses of the corrupted creatures looking around for
anyone
Pibby sighed and turned towards the portal, she steps inside and disappears through the portal
The portal then closes shortly after. - Original story ends here, my continuation starts here

They would eventually find a way to end the glitch, but the damage was permanent, and everyone they held dear, was seemingly dead…

Barry and Dokko went to try to save them, their dear friends had no pulse or heartbeat, They were BEGGING to revive them, tears gushing down their face,

In the obscure, ravaged remnants of Chamomile Valley, Barry the Bear and Dokko the Moose knelt in the dirt among the fallen, their dear friends now lifeless husks of their former selves. The air was heavy with the acrid stench of the glitch’s corruption, tinging the sky with an eerie, unnatural glow. Barry and Dokko grieved deeply, tears streaming down their faces as they tried fervently to rouse their friends from this dark slumber.

Barry laid his large, trembling hand on Krash the Rabbit’s chest, hoping against all odds for a heartbeat. Dokko, usually so composed, hyperventilated as he moved from one friend to another, shaking them, pleading for them to wake up.

“Please, Wally! You’ve got to wake up. We need your poetry to heal our hearts!”. Write a story where they are crying loudly, It is here that the Doctor from Doctor Who sees them, with Rose in tow
The sky above Chamomile Valley was an oppressive, glitchy void, filled with the aftershocks of the corrupted invasion that had left the land in tatters. Barry the Bear and Dokko the Moose knelt amidst the broken remnants of their world, the once-vibrant landscape now a desolate tapestry of black ooze and devastation.

Barry’s large, trembling hand rested on the chest of Krash the Rabbit, his best friend turned lifeless by the dark corruption. Tears streamed down his face as he pleaded for a sign of life, any sign. “Krash, buddy… please, come back to us. We need you. I need you.” His voice cracked under the weight of sorrow.

Dokko, usually the most rational and composed of their group, was unrecognizable in his despair. He dashed from friend to friend, tears blurring his vision, his heart pounding loudly in his chest. He shook Wally the Ram, whose gentle poetry had once been a beloved balm for their community. “Wally! You’ve got to wake up. We need your poetry to heal our hearts. Please, Wally, we can’t do this without you!”

Barry and Dokko’s cries of anguish resonated through the corrupted valley, a poignant testament to their undying love and loyalty for their friends. The glitch-infested world absorbed their cries, amplifying the heartbreak in a hauntingly beautiful symphony of loss and desperation.

It was in the midst of this heart-wrenching scene that a faint, almost imperceptible noise began to hum in the background. It grew in intensity, becoming more defined—a rhythmic, otherworldly sound that seemed to counteract the disharmony of the corrupted landscape. A strong wind picked up, swirling the dark ooze around them in chaotic eddies.

Suddenly, a large, blue, British police box materialized right before Barry and Dokko, its presence both outlandish and strangely comforting amidst the chaos. The door swung open, revealing a tall, mysterious figure with wild hair, a long coat, and eyes that glinted with determination and sorrow. Next to him stood a young woman with a fierce yet compassionate expression—Rose Tyler.

The Doctor briskly stepped out, his eyes scanning the devastated landscape before focusing on Barry and Dokko. His gaze softened, momentarily reflecting the profound grief etched across their faces. “Hello,” he said, his voice a mix of authority and empathy. “My name’s the Doctor. We’re here to help.”

Barry and Dokko, still overwhelmed by their attempts to save their friends, looked up through their tears. The Doctor’s presence seemed to carry a sense of hope, however slim, that perhaps all was not lost.

Rose stepped forward, kneeling next to the distraught pair. “We know what you’re going through,” she said softly, touching Dokko’s shoulder. “We’ve seen this kind of thing before. We may be able to help.”

The Doctor examined Krash, Wally, and the others with a grave, focused intensity. He took out his sonic screwdriver and scanned the area, the device emitting a series of high-pitched whistles and beeps. “This corruption—it’s not just in their bodies, it’s in everything. The fabric of this world is torn.”

Barry, still clutching Krash’s lifeless form, looked up with a glimmer of hope amid his tears. “Can you… can you bring them back?”

The Doctor hesitated, the weight of countless lost worlds behind his eyes. “I don’t know if we can bring them back,” he said honestly. “But we can try to clean up this corruption. We can give them a fighting chance.”

Rose nodded, squeezing Dokko’s hand reassuringly. “We won’t let your friends go without trying everything we can.”

With that, the Doctor sprang into action, using his knowledge and advanced technology to start attempting to purge the corruption from Chamomile Valley. Rose stayed close to Barry and Dokko, offering comfort and support as they stood vigil over their friends, their hope rekindled by the presence of the enigmatic Doctor and his brave companion.

As the Doctor worked tirelessly against the dark ooze, a new resolve took hold in Barry and Dokko’s hearts. They were not alone in this fight. And if there was even the slightest chance to save their friends, they would hold onto it with everything they had.
Write a story where they are revived, and as The Doctor and Rose leave, they get a call from Rose’s mum, saying “Your Grandad’s here”, and say what episode this sets up
The tension in Chamomile Valley was palpable as the Doctor worked relentlessly with his sonic screwdriver, its high-pitched hum slicing through the oppressive atmosphere. Rose, Barry, and Dokko watched anxiously as he manipulated the device, sending pulses of energy into the corrupted oozes that had swallowed their world and friends.

Minutes felt like hours, but gradually, a strange thing began to happen. The dark ooze receded, pixelating into nothingness. The lifeless forms of their friends—Krash, Wally, and the others—shuddered as if awakening from a deep sleep. Barry and Dokko held their breath, tears still streaming down their faces as hope fought to eclipse sorrow.

Wally’s eyes fluttered open first. He groaned softly, his body regaining color and life. “What… what happened?” he murmured, disoriented.

Barry let out a triumphant shout, hugging his poet friend tight. “Wally! You’re back! You’re alive!”

Krash followed, shaking off the last vestiges of the glitch. He blinked and saw Barry and Dokko’s tear-streaked faces. “Guys? What’s going on?”

Dokko nearly collapsed with relief and joy, his heart feeling lighter than it had in days. “Krash! I thought… I thought we lost you!”

The Doctor stepped back, a satisfied smile playing on his lips as he observed the miraculous revival. Rose’s eyes filled with tears of happiness as she watched the heartfelt reunions unfold. “See, I told you we’d do it,” she said softly to Barry and Dokko. “Now you can rebuild. Together.”

Barry and Dokko turned to the Doctor and Rose, their faces glowing with gratitude. “Thank you,” Barry said, his voice thick with emotion. “You saved them. You saved all of us.”

The Doctor nodded, his eyes twinkling with a mixture of joy and melancholy. “It was a team effort,” he replied. “But remember, this world needs to be protected. Stay vigilant.”

Rose’s phone rang, interrupting the moment. She glanced at the screen, a look of confusion crossing her face when she saw her mum’s name. “Mum?” she answered.

“Rose, sweetheart, your grandad’s here,” came Jackie Tyler’s voice, laced with urgency and confusion.

Rose’s eyes widened in shock. “Mum, I don’t have a grandad.”

The Doctor’s eyes met Rose’s, immediately sensing something was off. “What did she say?” he asked.

“She says my grandad is there,” Rose replied, bewildered. “But she means my dad’s dad, who, you know… shouldn’t be here.”

The Doctor’s eyes narrowed, gears already turning in his brilliant mind. “Something’s wrong. We need to get back to your mum’s place. Now.”

Barry and Dokko watched as the Doctor and Rose hurried toward the TARDIS. “Thank you again,” Barry called out, waving.

The Doctor waved back, pausing momentarily at the TARDIS door. “Take care of this world,” he said, before disappearing inside with Rose.

The TARDIS dematerialized, leaving Chamomile Valley just as swiftly as it had arrived. The sound of its departure seemed to echo a promise—one of hope, resilience, and new beginnings.

Back inside the TARDIS, the Doctor manipulated the controls with precision, setting their course for Rose’s flat. Rose stood by his side, worry etched across her face. “What do you think’s going on, Doctor?”

The Doctor glanced at her, his expression serious. “Parallel universes, alternate realities—when things like this happen, it usually means there’s a crack in the fabric of space and time. And we need to find out why.”

Rose nodded, determination replacing worry. “Let’s go see my mum and this mysterious grandad of mine.”

As the TARDIS hurtled through the time vortex, the Doctor and Rose prepared to face yet another enigma. The events would eventually lead them to a revelation that winded through the threads of their own lives and the fabric of the universe itself, setting up the episode “Army of Ghosts.”

The TARDIS landed with a familiar thud, the adventure continuing, and the ties that bound them growing ever tighter.
Write a epilouge where he says, What was I doing before being turned into a monster
As Chamomile Valley’s vibrant colors began to return and the final remnants of the dark ooze evaporated into the air, the newly revived villagers slowly pieced together the fragments of their interrupted lives. The sun peeked through the clouds for the first time in what felt like ages, casting a warm, life-affirming light upon the land.

Barry the Bear, still wiping away the remnants of his tears, stood with Wally the Ram under the shade of a large oak tree. Though exhausted, he could not help but smile at the sight of his friends gradually regaining their strength and energy.

Krash the Rabbit stood a few paces away, looking dazed but curious. His eyes darted around as if trying to reconnect with the familiar surroundings that had been eclipsed by chaos for too long. Eventually, he walked over to Barry and Dokko, who were engaged in quiet conversation.

“Barry,” Krash called softly, interrupting the bear’s thoughts. “What was I doing before… before all that happened? Before I turned into a monster?”

Barry and Dokko exchanged a look, and Barry’s eyes softened as he placed a comforting hand on Krash’s shoulder. “You were being your usual nosy self,” Barry said with a chuckle, attempting to lighten the mood. “Remember? You saw that strange ooze and got curious. None of us knew it was dangerous.”

Krash nodded slowly, the memory surfacing through the haze. “Right, I remember now. I wanted to see what it was. I never thought it would… change me like that.”

Dokko stepped forward, laying a reassuring paw on Krash’s other shoulder. “You couldn’t have known, Krash. None of us could. But look—you’re back now. We’re all back. And we can learn from this, make sure it never happens again.”

Krash took a deep breath, as if inhaling the fresh air for the first time. “Yeah. Yeah, you’re right. We’ve got a second chance. I guess we need to make the most of it.”

The trio looked around at the revitalized valley where their friends began to come together, sharing stories, laughter, and plans for rebuilding. Wally was already scribbling down what would surely be an epic poem about their harrowing experience and miraculous revival.

In that moment, surrounded by the hearty camaraderie and resilience of his friends, Krash felt a renewed sense of purpose. The darkness that had tried to claim them only made their bonds stronger, their determination fiercer.

Barry nodded towards the horizon. “The Doctor and Rose, they helped us get here. But now it’s up to us to keep moving forward. To rebuild what was broken—not just the valley but our spirits too.”

Krash smiled, a genuine, hopeful smile. “Let’s do it, then. Together.”

As the sun fully broke free from the clouds, casting its radiant glow across Chamomile Valley, the villagers began to repair their world, piece by precious piece. Every step forward, every act of rebuilding, was a testament to their collective strength and unyielding hope. They had faced the darkness and emerged stronger, ready to protect their cherished home with renewed vigour.

And while the Doctor and Rose continued their adventures through time and space, the seeds of their compassion and bravery had taken root in Chamomile Valley, nurturing a resilient community destined to thrive once more.
