Kimmy has to throw an acceptable kids' birthday party to keep her new job with the filthy rich Voorhees family.
Kimmy goes to Jacqueline Voorhees' house to ask for a second chance the keep her job. Jacqueline agrees but only if Kimmy can throw an amazing birthday party for her son, Buckley, before her husband, Julian gets home from his business trip. Kimmy accepts the challenge and then leaves to meet up with Titus. She tells him that she got her job back and now he doesn't have to work his low-paying job wearing his Iron man costume. Titus then realizes that he had to give a $200 security deposit to rent his costume in the first place, so now he can get that money back. He goes to the store where he rented his costume (Ray Ray's Costume Depot) from but the man working tells him he can't give him his deposit back because the suit is in bad condition (although it is not). Meanwhile, Kimmy prepares for Buckley's birthday party and meets Jacqueline's 15-year-old step-daughter, Xanthippe, who is stuck up and superficial. At the same time, Titus meets other people in New York City who have rented costumes from the same store but where not allowed to return them because they were told they were "damaged." Titus realizes that Ray Ray's Costume Depot is a scam. He and the rest of the costume renters who were ripped off get together and form a plan to expose the costume store. Titus notices that none of the costumes are actually what they are supposed to be (ex. Titus' costume is actually called "Metal Hero Friend" but Ray is selling the costume as "Iron Man" which violates copyright laws). The group uses this against Ray and forces him to give them their money back. At the Voorhees house, the birthday party goes well but Julian calls and says he won't be able to make it which upsets Jacqueline. Buckley didn't get any of the presents he wanted, and Xan tries to go out with her friends instead of being with her family. When all seems lost, Kimmy decides to turn everything around. She comforts Jacqueline about Julian, finds a way to ground Xan, and finds a way to give Buckley the best present ever.
