It's dance class day and Gran will teach Kwesi and the neighbours her trophy-winning dance, the Shooby-Doo Mambo. But Gran hurts her knee before Kwesi can learn all the steps. How will he learn the special dance now? Slowly Kwesi finds the confidence to practise the steps on his own, but dancing without Gran is not the same. Next dance class day, he and Gran dance the new Shooby-Do Mambo!
