Alvin and the Chipmunks
Miss Miller's first appearance is in Help Wanted: Mommy in which she takes in The Chipettes. She has difficulty transitioning into a mother figure for the girls as she initially treats them as babies and is a bit old-fashioned. Though she at first believes she isn't the best person to take care of The Chipettes, she grows to love and appreciate their company.
She also appears several times in the television series as The Chipmunks' baby-sitter or their driver. Miss Miller is shown to be dangerous in a car and the boys are usually terrified by her driving. She is seen in multiple episodes speeding, swerving across the road, and hitting objects such as fire hydrants and light poles. Her flying isn't much better as seen in Simon Says.
Miss Miller's memory is also not the best. For example, in Goin’ Down to Dixie not only does she forget the girls on the sidewalk to drive to the airport (she knew she forgot something but was unsure of what), she also forgot to buy tickets.
The Chipmunks Go to the Movies
Miss Miller's only appearance was in Funny, We Shrunk the Adults in which she plays the role of Zelda.
ALVINNN!!! and The Chipmunks
Miss Miller has so far only made a few minor appearances in Albrittina, Who's Your Daddy, and Bromance, with the exception of Mancave, The Great Chipmunk Detective and You Troll in which she has a larger role.
The Chipmunk Adventure
Dave hires Miss Miller to look after The Chipmunks while he goes off on a business trip. Alvin tricks her into thinking he is Dave with a voice mail. Later, Miss Miller accidentally runs Klaus and Claudia off the road as she is driving to the airport to pick up Dave since she drives the wrong way towards them.
Alvin and the Chipmunks Meet Frankenstein
Dave sent Miss Miller to look after The Chipmunks so that they do not miss the big movie premiere at Hollywood. Because the boys were reluctant to have her around the house at the time Frankenstein was there, Alvin lied to Miss Miller that Dave has changed his mind. Miss Miller, believing that Frankenstein is actually Dave wearing a costume, gets angry about this since she argues she should have been informed before having came to The Chipmunks' house.
Alvin and the Chipmunks Meet the Wolfman
Miss Miller is heard on the phone yelling at Dave because The Chipettes were frightened to death.
