Mr. Agar puts Carl on the school spring dance decorating committee as a punishment for slacking in class. Since Skye is busy lying down in front of bulldozers to protect a nest of burrowing owls, Carl brings in C2 to help with the decorations, so both of them are at school. The mess starts to happen when Chloe and Damien are also put on the committee as punishment. The day even gets strange for Lorna, as she keeps seeing two Carls! Her suspicion of Carl having a clone is further backed-up when she finds his blog! With the help of Jamie, Carl will have to play it smart to get out of this. Meanwhile, Chloe and Damien turns the "Spring has Sprung" dance decorations into destruction and chaos, much to Chloe's satisfaction.
