Mattie the Mouse

Matilda (nicknamed "Mattie" or "Mat") is one of Reader Rabbit's best friends. She is a feisty young mouse who likes to do everything and wears a yellow shirt,a blue dress with white buttons and a blue ribbon on her tail (only from 1989–1994). As a main character in Reader Rabbit Kindergarten, she finds some things that Spike is stealing. In Reader Rabbit: Playtime for Baby and Toddler she visits Reader Rabbit and goes into the book where it has so many fun worlds you can select. Mattie makes plenty of jokes! The song she sings is Mat's Song. She also appears in Interactive Math Journey (as a minor character) and in the video series Read Now!.
