Dreams of rock stardom take the edge off embarrassing family activities in Toms fourth "homework diary" crammed with doodles and stories.

After receiving the shock of a lifetime seeing his big sister, Delia, without her sunglasses on Tom is trying to gear himself up for sports day at school. It does not help that his dad is training for the parents race on that day and plans to wear bizarre cycling shorts! Meanwhile, Toms band, DogZombies, is supposed to play in the school talent show, meaning theyd better start practicing a lot. It might all be worth it, though, if the absolutely brilliant band DUDE3 appears as special guests!
