"Oh my god! I gave Harry Styles jungle worms!"
iGo One Direction, also known as iGot Jungle Worms, is the 2nd episode of Season 5 and the 96th episode overall of iCarly.
The half-hour episode drew 3.94 million total viewers and ranks as the week’s number-one kids show with total viewers on basic cable and scored the top spot for the week with kids 6-14 (7.1/2.2 million) and tweens 9-14 (7.9/1.6 million). 
Carly gets sick with Jungle Worms on a vacation. Although she is cured of her symptoms after two days, Dr. Dresdin warns that she might still be contagious. When the British-Irish boyband One Direction accepts an invitation to iCarly, band member Harry gets sick after he drinks from Carly's water bottle. He's still not better after a week and Carly takes care of him. At the Groovy Smoothie, the others are wondering why Harry isn't better after a week. Sam tell the others how Harry is better but just faking his illness because he likes Carly taking care of him. In order to get him to confess, they make up a lie that they want to accept Gibby, a huge One Direction fan, into the band. Harry is so shocked by the idea that he stops pretending to be sick, and One Direction performs their song "What Makes You Beautiful" on iCarly.
Meanwhile, Spencer finds an exercise machine on the junkyard. It catches the eye of an attractive woman named Justine, so Spencer claims to be a personal trainer in order to impress her. Unfortunately for him, she doesn't want to train, but rather sends her bratty daughter Bethany. Spencer eventually talks to the girl about how she has to be nicer and tries to give her a makeover, but fails.
