Kave-Tina Rox by Jill Marshall
Kave-Tina Rox lives with her Mug, Pug and brother Dave-Kave in a cave. Her Mug tries to brush her hair and make her look pretty, but Kave-Tina's having none of it. When the Caveman Games come to town, Dave-Kave doesn't let her join in with any of the games, because she's just a girl, but Kave-Tina's having none of it. She shows she's perfectly capable of joining in, and indeed of doing it better than Dave-Kave and his mates.
