When Mum and Dad have a disagreement, Bluey makes Dad write a love letter to Mum to make up. Now Bluey must find a way to play Ground's Lava with Bingo and deliver the letter to Mum, without squabbling.
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.
