It was a sunny day when Mark, Derek, Ash, Violet and Sam stepped into the infamous Inflation Park. The park was well-known for its magical fruit jellies that made people big, round and fat.

Shortly after their arrival, they spotted a man munching on a big, shiny jelly. As he consumed the last bits, his body magically expanded, making him look like a giant balloon.

A tall, round woman came over and chuckled at the sight, teasing the man by calling him a 'big boy'. With her strong arms, she effortlessly guided the round man away from the crowd.

Mark turned to Derek, unsettled by the scene. He suggested they leave, but before they could respond, a booming voice echoed throughout the park, "There's no escape now!"

Just then, Ash accidentally knocked over a basket of fruit jellies. Trying to correct his mistake, he hastily consumed one, and before their astonished eyes, Ash's body bloated up, making him round like a ball.

The round woman spotted them instantly. She waddled over, her laughter ringing out loud, and teasingly called Ash a 'plump pumpkin', much to the amusement of the onlookers.

With Ash taken away, the group was left in a state of panic. Yet, their predicament did not end. The crowd around them started shouting nicknames for each one of them, goading them to eat the jellies.

Under the pressure, Violet ate a jelly. Her transformation was swift and she became as round as Ash. The woman, delighted, teased Violet by calling her a 'huge raspberry'.

Sam was next. He put up a fight but was ultimately forced to eat a jelly, and just like his friends, he ballooned into a massive form. The woman called him a 'massive mango'.

Mark and Derek were left. Mark was visibly shaking but gathered his courage, picked up a jelly, and ate it. His body swelled up, and he was promptly teased by the woman as a 'bulging banana'.

Finally, it was Derek's turn. He sighed deeply, met the woman's eyes, and ate a jelly. He matched his friends in roundness and the crowd cheered as the woman dubbed him 'a delightful donut'.

With all of them fattened up, the woman started leading them away. She declared that she was taking them to the Jelly Zoo where they would be the newest attractions.

The Jelly Zoo was filled with creatures of all shapes and sizes, all of whom had eaten the magical fruit jellies. It was a cacophony of colours and noises, as round beings bounced around.

Despite their predicament, the friends could not help but marvel at the sight. They were large and round, but they also found a strange sense of camaraderie with the rest of the zoo's inhabitants.

Over the next few days, they adjusted to their new lifestyle. They learned the art of rolling instead of walking, and even how to bounce high enough to pluck fruit from the trees.

They even developed a fondness for their new forms. They enjoyed the warmth of the sun on their round bodies and the softness of their skin. The teasing from the woman and the crowd became a routine.

Amongst them, Derek was the first to embrace his big figure. He started participating in races against other inhabitants and even won a few. The others soon followed his lead.

One day, they spotted the woman coming towards them, a big smile on her face. She told them that they were the stars of the park, and their jolly natures had become the highlight for the visitors.

She then revealed that the effect of the jellies was temporary. If they wished, they could return to their normal sizes. But to their surprise, none of them wanted to.

They explained to the woman that they had grown to love their round bodies. They had made friends in the zoo, they enjoyed the competitions, and were used to the teasing.

So, they chose to stay, their round bodies bouncing and rolling around the Jelly Zoo, becoming a source of joy and amusement for visitors. They claimed their nicknames and wore them with pride.

As the sun set over the Jelly Zoo, Derek, Mark, Ash, Violet and Sam were seen happily bouncing, a picture of joy and contentment. The woman watched on, a satisfied smile on her face.

From then on, they became legends in the park. Their story spread and many came to witness them - the delightful donut, the bulging banana, the massive mango, the huge raspberry, and the plump pumpkin.

Their friendship stood the test of time and they lived out their days in joy, never regretting their decision to stay in the Jelly Zoo. Their once ordinary day turned into an extraordinary adventure.

And so, even today, if you ever visit the Inflation Park, you'll see five round friends, enjoying their lives, teaching everyone that sometimes, it's okay to be different and embrace change.
