The iCarly gang becomes interested in dancing after Mrs. Briggs invites a Scottish Highland Dancer to class. As a contest on iCarly, they decide to announce a dance contest where fans could send them videos of them doing their best, worst, craziest, or stupidest dance moves and if they're good/bad/crazy/stupid enough, they'll show them on iCarly to the world. When they get over 3,000 videos and wonder how they’ll watch that much before the next show, they decide to watch 500 a night. The iCarly gang tries watching the dance clips, but soon ends up falling asleep and having dance-related dreams.
They all have separate dreams but, before that, they have a dream that they all share. The dream is where Carly, Sam, and Freddie walk into school, tired from watching the 500 clips, and they all admit that they don't even remember getting up that morning. Then, the school lights dim, and every student in the school, except for the trio, start dancing, leaving the group to wonder what's going on.
