This fifth Clem book celebrates sporting competition, just in time for The Olympics 2016! When Clem and Syr Boblihosan discover a Very Exciting Sports Competition at their local sports centre, they are so excited. They are even more excited when they are asked to take part. But Clem's doggy paddle isn't fast enough, and he's not quite as good at gymnastics as he thought he might be.
