Meanwhile, the episode also explores the backstory of Johnny's name and his family's observance of a family tradition.

The episode begins with Johnny and his friends, Dukey and Gil, working on an experiment in their lab. They create a chemical which can grow anything instantly, including a monster. Johnny and his friends decide to test the chemical by growing a pet monster for themselves. They take the monster home, but their little sister Susan gets her hands on the monster and decides to take it to show-and-tell. As expected, the monster wreaks havoc in the classroom, and Susan gets into trouble. Johnny and his friends then must figure out a way to stop the monster and save their sister from getting punished.

In the meanwhile, Johnny's parents reveal the story behind Johnny's name. They explain that Johnny was named after his great-grandfather, who was a legendary adventurer and explorer. Johnny's parents reveal that it is a family tradition for the firstborn son to embark on an adventure on his sixteenth birthday, just like his great-grandfather did. Johnny is excited to learn about the tradition and decides to prepare for his own adventure. Johnny's sisters, Susan and Mary, also take an interest and try to help Johnny prepare.

As the episode progresses, Johnny and his friends come up with a plan to stop the monster. They try to talk the monster into leaving peacefully, but it doesn't work. They then come up with a distraction plan, which also fails. Finally, Johnny uses his ultimate weapon, his annoying singing voice, to defeat the monster and save his sister.

The episode ends with Johnny and his friends being reprimanded for their experiment, but their parents are proud of Johnny for using his singing to defeat the monster. Johnny's parents also realize that Johnny doesn't have to go on an adventure if he doesn't want to, and they promise to support him no matter what he chooses.
