The ZingZillas are practicing The High Notes and Low Notes Song. Zak sings all the low parts and Panzee sings the high part. But she can't reach the highest note. Panzee realises that she can't sing the high note. Downstairs in Todd's garden Panzee suddenly hears a very high note coming from the jungle. It is the perfect note for the song, but where is it coming from? Drum races off to find out. Meanwhile Zak and Tang sit with Drum in the Glade and watch Frank Perry play notes by tapping bowls around him. It is the perfect sound for the Big Zing. Back in the jungle, Todd gets out his Noise-A-Tron - a device that detects which direction a sound is coming from.
