Tedward makes the kids enroll in Jaget's new martial arts class. While Lex, Presley, and Munchy don't feel like they've actually learned anything, Jaget makes them take on the burly students of a rival martial arts class.
Smart and sarcastic Lex, tough and confident Presley, and their quirky friend Munchy find themselves in a sticky situation after an accidental mishap destroys a boat belonging to Munchy's dad Principal Tedward. Forced to come up with creative ways to earn money to pay for the damages, the best friends enlist the help of Presley's tech-savvy younger brother Fisher to create an app called "Kid-DING" to connect with people looking for help with small jobs. With Munchy's bossy older brother Jaget making sure they keep up with the payments, the three friends must do any jobs that come their way no matter how crazy they are.
