Susan and Mary have come up with an app that can physically change the face of whomever's picture is taken with the camera phone. Johnny naturally takes it for a spin for some fun, but when he pranks Bling Bling Boy using it, Eugene decides to take revenge by swiping his phone and using the app for his own ends. Johnny and Dukey have to get the phone back and clean up the messes Eugene causes with the app in the process.
Tropes:
- Frame-Up: Eugene uses the face changing app to commit some minor crimes while wearing Johnny's face in order to get the real Johnny in trouble.
- Laser-Guided Karma: At the end, Johnny uses the app to turn Eugene's head into the poo emoji, which his scientists state will take three months to reverse.
- Revenge: Eugene does this against Johnny and Dukey just for making him drop his free ice cream. It's likewise Disproportionate Retribution since dropped ice cream isn't exactly worth something over pulling a Frame-Up and getting law enforcement involved.
- Why Did It Have to Be Snakes?: When the sisters reveal they put some clown faces in the app, Johnny and Dukey reveal that clowns are scary to them. Later, Eugene hits them all with clown faces.
