The Chipettes' Treehouse is where The Chipettes live and/or hang out. The Chipettes originally lived alone in their tree-house during the Alvin and the Chipmunks series until Miss Mooney, a school teacher, discovers and reports that the girls are living without an adult in Help Wanted: Mommy. As a result of this information, The Chipettes briefly live with The Chipmunks at the Seville House before deciding to live with Miss Beatrice Miller at the Miller House, where they live throughout the rest of the 80s series. The tree-house was used afterwards as a place to hang out.
