Abby choreographs a bully themed dance that sends Holly over the edge. The Abby Lee Dance Company is shaken-up when Abby replaces cheerleader Brooke with a new girl and switches girls in and out of dance numbers, sending the Dance Moms into a frenzy. Meanwhile, during cheerleading, Brooke learns the hard way that the grass isn't always greener.

It's "solo week" and Abby is fed up with the moms complaining about costumes so she makes them design new costumes for their kids...but Jill has a closet full of costumes that Abby has never seen before. Cathy holds a big open audition to supplement her Candy Apples.
