Carly's old friend Missy Robinson returns to Seattle and tries to become Carly's only best friend and replace Sam because she was Carly's best friend first. Sam was given expired chocolate by Missy, and she destroyed Sam's cell phone, and in addition, Missy texted Sam the wrong address to a helicopter base, that she intended to go on with Missy, and Carly. Missy's actions are claimed "accidental", however Sam realizes what Missy is trying to do, but no one believes her as they think Sam is being "her usual paranoid self", because she was being paranoid when she thought Lewbert was an undercover cop, because she thought his giant wart was a spy cam and thought Gibby was a mermaid because he doesn't like wearing shirts. Missy confesses to Sam, but since no one will believe her, she is forced to ask Freddie for help, so when Freddie wins a six month cruise, he gives it to Missy so she will go away. Shortly after Missy is awarded with the cruise, Carly discovers Missy's plans to destroy her and Sam's friendship.

After an episode of iCarly, some kids at school mention that a show on the Dingo Channel called "Totally Teri" used Random Dancing in an episode, calling it "Random Jumping".

Visiting Dingo Studios, Carly and Sam learn the "Totally Teri" writers are plagiarizing iCarly skits for their own use, and they claim they have rights to do so, since they have money and power. Meanwhile, Spencer and Freddie find Charles Dingo's (the founder of Dingo studios) head and come up with a plan (along with Sam and Carly), since they have access to the head. The next day, the iCarly group threatens to release depictions of Dingo's head on iCarly.com unless the writers swear never to steal the show's ideas again; Afterwards, two of the writers end up on iCarly in a skit called "Bikini Dog Food Fight".
