one character comes up behind another and helps them floss

When Floss stays with her godmother Lillian after the death of her mother, the pair form an unlikely friendship.

Life isn't always easy when you're a Toothbrush. Just ask him and he'll tell you all about it. Or ask his best friend, the laid-back Floss. He's heard about Toothbrush's sob story so many times he could recite it flosslessly.
