<P> After their computer monitor and TV (which was found in the dumpster behind El Taco Guapo and was stolen by a man sleeping next to it) are stolen, Spencer starts developing a security robot . At first, he builds one that blinds intruders, but takes it apart after it accidentally blinds Carly . He then makes one that shoots corn at intruders, but it malfunctions and accidentally attacks Carly, Freddie and Spencer . They try to have it focus on Mrs. Benson and unplug it, but Spencer forgets to pull the plug out of the outlet before the machine runs out of corn, so Mrs. Benson is heavily pelted with corn . Meanwhile, Sam and Gibby open a secret restaurant named Gibby's in the basement at school . Bully Billy Boots harasses and annoys Gibby . Sam tries to intervene by sending Gibby to go on a walk and trying to talk to Billy, but when Gibby returns later, Billy attacks him and Sam beats up Billy with a Butter sock . The next day, Billy tells Mr. Howard about the restaurant and hopes it gets shut down . Even though Principal Franklin, who is one of Gibby's customers as well, agrees that the restaurant violates numerous school rules, he approves it and lets Sam and Gibby keep running it secretly until Mr. Howard is out of earshot . </P> <Tr> <Th> 88 </Th> <Td> </Td> <Td> "iHalfoween" </Td> <Td> Adam Weissman </Td> <Td> Dan Schneider & Ben Dougan </Td> <Td> April 28, 2012 (2012 - 04 - 28) </Td> <Td> 505 </Td> <Td> 2.9 </Td> </Tr> <Tr> <Td_colspan="8"> <P> Carly, Sam, and Freddie wonder why people never celebrate Halloween more than once a year .

Carly dresses up as a life - size serving of tuna sushi, Sam dresses up with a hat with "hand sanitizer" on it, and Freddie dresses up as Lewbert . Once Nevel finds out, he dresses as a purple robot and give the "iCarly's" candy, which changes their voice and freaks out many people . Because of this, they angrily split up to find out who the purple robot is . Freddie successfully finds Nevel in the iCarly studio .
