Two popular live-action cartoons join forces for a mini-movie of sorts, “iParty with Victorious” on “iCarly” (7 p.m., Nickelodeon). “iCarly,” set in Seattle, and “Victorious,” set in Los Angeles, meet and mingle in the city of Angels after Carly (Miranda Cosgrove) discovers that her dream boyfriend of nearly 100 days is carrying on a parallel romance with Tori (Victoria Justice).

After discovering this two-timing online, Carly also discovers that he and his lady conquest will be attending a posh party at a borrowed celebrity home in the Hollywood Hills. A road trip, a party and a confrontation ensue, accompanied by a ventriloquist dummy and a badminton racket-wielding panda bear. Don’t ask.

As crossover episodes go, “iParty” is no more contrived than usual. However if its intentions were to proclaim equality between its teen brunette stars, it fails miserably. Carly is clearly the more clever and proactive character and her quirky ensemble of pals more interesting. Tori seems like just another pretty girl who expects the party and the attention to come her way. On both “iCarly” and on her Internet show within the show, Carly is both the star and producer. And it’s clear that the writers and producers of this series respect her, I mean, their, career path.

As always, there is the matter of Carly’s creepy older brother (Jerry Trainor), who in this episode is continually trying to get the teens to cover him with lotion and give him back rubs. Maybe he can get his own show called “iPredator.”
