It is the night of the Night-time Big Zing and Drum is really excited about staying up late. But the other ZingZillas have to persuade her to have a sleep in the afternoon first or she will be too tired to play. Tang tries to tell Drum but when he says Big Night Zing she dashes off in excitement. DJ Loose thinks he can help so Tang and DJ go to the Glade. They see a harp being played by Catrin Finch. The dreamy sound of the harp gives Tang an idea! The Band can write a lullaby to send Drum to sleep. Back at the Clubhouse the band rehearse the lullaby, while down below Drum has heard the sweet music and has curled up and gone to sleep. Todd suspects that she was excited about the Big Night Zing. Drum hears this, wakes up and dashes into the jungle in her excitement. Now the ZingZillas have to catch her again! Eventually they find her in the Glade, fast asleep, listening to the harp playing. However it is now evening and time to wake her up! The ZingZillas gather to play the Big Night Zing Drift Away accompanied by the harp. At the end of the song the tired Drum does drift away to sleep - finally.
