Carly Shay (Miranda Cosgrove) (iCarly) is dating a boy named Steven Carson (Cameron Deane Stewart), who divides his time between his divorced parents in Seattle and Los Angeles.

Carly, her brother Spencer (Jerry Trainor), Sam, and their friends Freddie Benson (Nathan Kress) and Gibby Gibson (Noah Munck) travel to Los Angeles.

They visit Spencer's ex-girlfriend, Monie (Jen Lilley), who happens to be a skilled make-up artist, and receive disguise makeovers to avoid being noticed from iCarly by others.

Meanwhile, while having lunch at Hollywood Arts High School in Los Angeles, Andre Harris (Leon Thomas III), another friend of Tori's, announces that his real estate agent uncle sold a house to Kenan, who gave permission for Andre to host a small party there as he scheduled to move the month after since he is in New York.

Spencer discovers that the house includes a jacuzzi and relaxes in it, leading to him meeting Tori's teacher Sikowitz (Eric Lange) and her friends Beck Oliver (Avan Jogia) and Jade West (Elizabeth Gillies).

Sinjin Van Cleef (Michael Eric Reid), another student at Hollywood Arts, falls into the jacuzzi when a surfing arcade game malfunctions.

The iCarly members remove their disguises, Carly and her friends explain the situation to Tori, and together they come up with a plan to humiliate Steven.

As Kenan and Andre are trying to catch the Panda stalker, the iCarly gang and Tori eventually convince him to join their plan.

Meanwhile, in the iCarly episode "iApril Fools", Carly, Sam, Freddie, and Spencer appear in Tori's living room sitting next to Robbie, who is actually a transformed version of Gibby.

Verne Gay of Newsday gave a positive review, suggesting "iParty with Victorious" may be the biggest event of the mid-2011 and noting the scene depicting a guy in a panda costume chasing Kenan Thompson was hilarious.
