Bluey can't get to sleep, so Mum reads her one last story. But they are interrupted by Unicorse, the most annoying hand puppet in the world, whom Bluey tries to reform.
Bluey is an anthropomorphic six-year-old Blue Heeler puppy who is characterised by her abundance of energy, imagination and curiosity of the world. The young dog lives with her father, Bandit; mother, Chilli; and younger sister, Bingo, who regularly joins Bluey on adventures as the pair embark on imaginative play together.
