Mrs. Sanban

Mrs. Sanban (voiced by Lauren Tom) is a minor character that appears in Alvin and the Chipmunks 2. She is the biological mother of Kuki and Mushi, and also the wife of Mr. Sanban. However, Mrs. Sanban is completely unaware that King Sandy is her son-in-law. Going into the haunted mansion that is located in 35th Jasmine Street, Mrs. Sanban begins toying with some of the equipment lying around the ground, eventually climbing up onto the second floor of the mansion that leads to the haunted attic. Finding a rope, Mrs. Sanban begins swinging from it for fun, catching the attention of and annoying Hoagie Gilligan (voiced by Benjamin Diskin), who demands Mrs. Sanban to come down. Unseen by Hoagie, Mrs. Sanban was ultimately grabbed, attacked, and ambushed by Augustus Miyamura (voiced by Willem Dafoe) from behind, where Augustus impales her to a wooden door through her throat with a sharp butcher knife. Shortly before Augustus can kills him too, Hoagie finds Mrs. Sanban's lifeless corpse; as Hoagie is staring in horror at Mrs. Sanban's lifeless corpse, Hoagie is ultimately attacked and murdered by Augustus in cold blood, who impales him with another sharp butcher knife. After killing Hoagie in cold blood, Augustus rolls his lifeless corpse onto the bottom floor of the mansion and later hangs it upside-down from a yellow frangipani tree. Hoagie's lifeless corpse, presumably still hanging upside-down from a yellow frangipani tree, is later found and buried by the authorities until Alvin (Justin Long), Simon (Matthew Gray Gubler), Theodore (Jesse McCartney), Brittany  (Christina Applegate), Jeanette (Anna Faris), Eleanor (Amy Poehler), Mr. Blik (Wayne Knight), Gordon Quid (Rob Paulsen), Waffle (Kevin McDonald), and Human Kimberly (Liliana Mumy) revealed themselves.
