The gang are holding a car boot sale in their garden. Bungle makes a poster to let people know about the sale, while Zippy makes a model snowman to sell Meanwhile, George is collecting things together to sell at the sale. Rod and Freddy have been sorting out items to sell and arrive with a wheelbarrow full of things. Rod finds an old banjo and gives it to Jane to put into the sale, but Freddy stops them, telling them it was his Grandad's and is very sentimental to him. Freddy sings a song his Grandad used to sing to him when he was small called "I Used To Play My Old Banjo". George decides to give his old Wellington boots that no longer fit him to the sale and has painted them in all the colours of the rainbow. It's almost time for the sale to begin, and Zippy makes fun of Bungle because he thinks he hasn't made anything for the sale. But Bungle has the last laugh. Jane opens the sale and everyone has a good time browsing the items for sale and playing Bungle's game.
