In the ending, when the audience learns the Warner brothers and Warner sister are royalty, all their shenanigans become one big Stealth Pun when it dawns: they are a royal pain.
Furthermore, with the Warners being royal, Dot's full name is excellent foreshadowing: Princess Angelina Contessa Louisa Francesca Banana Fanna Bo Besca III.
Mindy finally calling her mother "Mom" at the end of the story is likely because of her overhearing Dot’s story about her parents during her Disney Death scene that reminded her what a mom is and how lucky she is to still have one.
