Some time passed and Zack soon began to get bored so he proceeded to say, "I'm 16 again."
In a matter of seconds, Zack returned to his original age and was about to leave the beach until something caught his attention. He saw that nearby there two teenagers who were laughing at a toddler who had just had a diaper blowout and his parents were trying to calm him down.
Zack found it unpleasant that those two chicks were making fun of what just happened to that poor kid. They even took photos of what happened. So Zack decided to use his potion to teach those two a lesson.
"Those two teens are 2-year-old toddlers with full, dirty diapers. Not to mention their minds are still intact."
And in a matter of seconds, those two teenagers immediately transformed into 2-year-old toddlers. They were not only horrified to see that they were now infants, but were now only wearing swim diapers which were completely filled and smelled pretty bad. Their situation was so embarrassing that they began to cry and proceeded to run for their mothers.
Now that he had finally taken care of those two, Zack proceeded to leave the beach and began to think about where he would go next.
