The ZingZillas have a swinging train song to sing, so DJ introduces us to the BBC Big Band playing a train-sort of tune, but Panzee and Zak can't agree who is going to be the driver of the train - whether "choo-choo" or "whoo-whoo!". If they don't settle their argument there'll be no Big Zing! But they manage to sort it out with Zak in the leading saying choo-choo and Panzee in the lead saying whoo-whoo! They're now ready to play!
