After Maceo's dad, Albert, injured himself in the premiere episode, host Philip Lawrence declared all 12 teams safe from elimination, making this week's "Pop Night" the first emotional goodbye of the season. The talented kid dancers and their untrained parents continue the competition of a lifetime, dancing to iconic songs from some of the biggest pop artists, including "Turn Down for What" (DJ Snake and Lil Jon), "Uptown Funk" (Mark Ronson feat. Bruno Mars), "What a Man Gotta Do" (Jonas Brothers) and "Rollin" (Limp Bizkit)

The second wave of five kids tasks their dance partners with learning three new moves that they must pull off during their performances. The five remaining teams perform dance routines to "Level Up" (Ciara), "Cheap Thrills" (Sia) and "Pump Up the Jam" (Technotronic), on part two of a two-part episode.
