The children of Greendale have been practising for Karaoke Night and cannot wait for it to be time to sing. Everyone has a musical number prepared and they are ready to shake their stuff on the special stage that's been put up. The karaoke machine is pretty special too - it's solar powered! But it turns itself on in Pat's van and all its charge is used up, so it turns itself off halfway through the night!

Ajay is organising a Summer Special day on the green, but the weather is too hot for everyone to enjoy themselves. Hopefully, Ted's new invention and Pat's special delivery may save the day if all goes according to plan.
