The Meanest Doll in the World is a children's novel written by Ann M. Martin and Laura Godwin and illustrated by Brian Selznick.

They plan to return to school and get back into Kate's backpack and then home to their worried families.

At the Palmers' house, Mimi pretends to cry and tricks the Dolls and the Funcrafts into letting her stay with them.

Mimi tries to wake up Kate so she will know about the mess she made and blame the Annabelle and Tiffany.

The story concludes with Mean Mimi, still in Permanent Doll State, being taken back to Kate's school where she ends up in the lost and found.
