Once upon a time, Zeynep played with her colorful blocks, laughing and building tall towers.

After using the toilet, Zeynep hurried back to her game, forgetting to use soap to clean her hands.

Tiny bacteria cheered, 'Hooray! No soap! Let's sneak into her body before she remembers!'

Zeynep's mom offered fruit, asking, 'Did you use soap, dear?' Zeynep paused her game.

She rushed to wash her hands with soap, but some bacteria had already begun their journey.

Her mom brought a fruit plate, but Zeynep chose wafers instead, unwrapping them eagerly.

The bacteria inside celebrated, 'Sweet treats for us! This will make us strong and mighty!'

They dreamed, 'With more candy and no veggies, we'll grow powerful and maybe make her sick.'

As time ticked by, Zeynep's tummy began to ache, 'Ouch!' she gasped, clutching her belly.

Zeynep felt uneasy and remembered the unwashed hands and junk food. She grew worried.

Her mom noticed her discomfort. 'Let's eat some fruit, it might help your tummy,' she suggested.

Zeynep agreed, munching on apples, her body fighting back against the unwelcome guests.
