Not long after the events of "Rainbow Rocks," Rainbow Dash, Sunset Shimmer and the Great and Powerful Trixie end up pocketing the Dazzlings' broken amulets after the show. However, the Equestrian magic infused in the artifacts starts to create a new trio of the Sirens to replace the failures of Adagio Dazzle and her band. Can the remainder of the Rainbooms fend off the new Dazzlings with their latest plan to suck the admiration out of the school for their personal gain?

In case it's not clear, this story was written before "Find the Magic" with just the Dazzlings missing after getting thrown out of their concert during the Battle of the Bands.
