Madame Shhh hosts the event in Bubble Land. Selected participants are notified by a ringing rainbow bubble which relays a hologram message from Madame Shhh herself. HJ5 and the Tanaka Boys were the only music groups that were seen participating in the competition.
Each band got their own personal bubble-home with a built in kitchen, lounge, bedroom, and music studio. Madame Shhh reveals each band can only pick one song, which causes Music and G to argue over whose song should be picked.There is currently no other information available as the event never officially started.
