Mary Jessica Gibbs (born October 5, 1996 in Pasadena, California) is an American voice actress. At age three and a half, she gave voice to the toddler Boo in Disney/Pixar's Monsters, Inc. Her age at the time made it difficult for her to record dialogue while confined in a sound booth, so the recording crew followed her around the studio for several days and recorded the baby-talk sounds she made. These recordings were edited into the film as her character's dialogue. Uncredited, she voiced baby Nala in the Lion King merchandise and a little girl named Sha-Ron in Mulan 2.
