Sonny meets Chad Dylan Cooper, the star of the number one tween show MacKenzie Falls, during a fro-yo (frozen yorgurt) run for her cast mates. Chad mistakes Sonny for a waitress due to her costume, and steals her yogurt under the guise of giving her his autograph. Upon returning to the Prop House with the melted yogurt, cold burritos and 12 AAA batteries, different from what her cast mates have requested, Sonny learns that MacKenzie Falls and So Random! are rivals, due to a Tween Choice Award interview with Chad Dylan Cooper mocking So Random!. Tawni reveals that the So Random! eventually stole their parking spot and their Tween Choice Award (which they use as a toilet paper holder as revenge).
When Sonny goes over to Mackenzie Falls to confront Chad, Chad distracts her by taking her hand and looking deep into her eyes and giving her a very heartful speech, this is where Sonny first starts to fall for Chad.
In an attempt to end the rivalry between the two shows, Sonny invites the cast from MacKenzie Falls to a so-called "peace picnic." Instead of promoting peace between the two shows, the feud becomes worse when the cast members of MacKenzie Falls put glue on the So Random! cast's chairs, take a picture of Grady's butt, throw egg salad on Sonny's face, takes the Tween Choice Award trophy back and post the picture of Grady's butt and the video of Sonny getting hit with an egg salad on the face on the internet. Sonny barges onto the MacKenzie Falls set, only to return to her dressing room. When the rest of the cast of So Random! mocks her and says she didn't get anything, she bluffs and tells them that if they beat the cast of MacKenzie Falls at something, the cast of So Random! will get all of their stuff back.

Sonny manages to convince Chad to play musical chairs after barging into the MacKenzie Falls set
