Bingo is just in the backyard enjoying some flossing. She’s practicing a bit when Bluey comes up to her and asks if she wants to play grannies. Bingo obliges and the girls then proceed to be two destructive grannies. Bingo comes out of character every once in a while to floss again and the age old question arises: can grannies floss? They recruit the help of Nana and Bob and when they discover that Grannies can’t indeed floss, Bingo is a little annoyed and leaves the game. Bluey is upset that Bingo left but also knows that she's right, so she remedies that by having Nana learn how to floss and Bingo is super happy about it and they keep playing. They barrel Bandit over with their car, he hurts something in his back, and the girls stand there and floss as Chillis helps Bandit and they both dream together of their future of flossing when they’re old and gray.
