The Plonsters want to have a picnic in the autumnal forest and have barbecued chicken. In order to fan the fire, Pliff turns himself into a large ventilator, turns himself onto turbo speed and becomes the cause of a forest fire. They have to call out the Plonsters fire brigade: Plummy as a fireman, Pliff as fire engine, Plops as the water hose. And from now on, chickens will only be cooked in the microwave.
