Timmy Turner had been gaining weight at an alarming rate. His thin frame had started to fill out, his belly curving outwards and spilling over his pant's waistband.

His parents were perplexed by this sudden change. They didn't understand why their son was gaining weight when his eating habits hadn't changed.

One day, while Timmy was at school, his button popped off from his pants, unable to withstand the pressure from his expanding belly.

"This can't be normal," Timmy thought, feeling embarrassed and uncomfortable. He decided to avoid his favorite desserts, hoping it would stop his weight gain.

Meanwhile, his mom started making him shakes, telling him they were packed with vitamins to keep him healthy. In reality, she was adding weight gain powder into them.

Timmy's friends noticed his weight gain too. They tried to be supportive, but Timmy could see the confusion in their eyes.

Timmy's parents took him to the doctor, who was also baffled by Timmy's sudden weight gain. He recommended a change in diet and more physical activity.

Timmy started to exercise more and stopped eating desserts altogether. But his weight kept increasing, making it difficult for him to move around easily.

His mom kept making him the shakes, believing they were helping him. She was oblivious to the fact that the weight gain powder was making him bigger.

Timmy's friends started to worry about him. They knew something wasn't right, but they didn't know what to do to help him.

One day, while cleaning his room, Timmy's mom found the empty can of weight gain powder. Realization dawned on her as she read the label.

She quickly stopped making the shakes for Timmy. Feeling guilty, she apologized to him, confessing her unintentional mistake.
