In the future, Miriam passed away. It is implied that Miriam died from depression after her husband was sent to the Planet of the Dads to be a slave and she suffered from progeria. The Dinkleberg's house was given to the Mulligans, and a retirement home was built and named in honor of Miriam.
After Miriam died, instead of her being buried at the cemetery, Dante and Daran had thrown Miriam's body into the ocean filled with sharks.
She has the same nose and face shape as Mr. Dinkleberg, and has red hair. Although Mr. Dinkleberg is known for having everything better than the Turners, his own wife is usually considered more unnatractive than Mrs. Turner. Despite being the same age as the Turners, the Dinklebergs have an older appearance. She wears mainly out-of-date clothing, appears to be a little chubby, and seems to have the same interests as Mrs. Turner, which, rather than a friendship, leads to bitter rivalry.
