A band of primate friends play music in their tropical island paradise and meet different musical guests. It's early in the morning and Zak is still fast asleep. DJ Loose introduces Tang, Panzee and Drum to Stuart Zender who is playing slap bass guitar. The ZingZillas love the tappy, slappy sound and DJ explains the technique is called slap bass because of the way you slap the guitar strings with your thumb. With a bit of practise Panzee plays slap bass too and she can't wait to play it to Zak. However, Zak is very upset because his special breakfast banana has gone missing and he thinks someone has eaten it. All he found was a banana skin with no banana in it. He declares that he can't write anything for the Big Zing until he finds out who ate his banana. Todd likes nothing more than a good mystery so he suggests they look for some clues. However all the clues they find appear to point to Zak, so they decide to lay a trap to catch the culprit.
