Out of all the bizzare shapes and sizes in the box, the one that catches your eye is a whole chocolate bar, with a blue color. you start eating it. it tastes like you're eating solid gold. As in, it tasted unnaturally good.you were on the last , and bit into it. oddly, it blew up, getting all over your clothes. even more oddly, your skin was untouched by the blue droplets. it soaked all the way through your pants, getting on your underwear, but stopped and refused to go deeper and touch your skin. Suddenly, you felt like you were in a car compacter becoming compressed from all sides. You started shrinking. the chocholate on your clothes made them shrink, too. You felt years of age slip away, and your clothing was regressing with you. soon, you were out of your teens and well into childhood. Soon after, you stopped regressing. you were 2 years old.
You tried a red chocholate that tasted like The blue. however, absolutely nothing happened. you sat for hours in your 2 year old body, waiting to see if that would fix you. you then read the box under these chocolates.
Warning, the first you take will result in a change, and all other chocolates will not do anything afterwards, so your stuck as such unless other means repair you.
