Fifteen years ago, the Pixar classic that is Monster's Inc. was released.
Starring John Goodman and Billy Crystal, the animated feature followed monsters working in a corporation that uses the screams of children to generate power for the city.
However, the monsters have a change of heart when they meet Boo, a small, adorable girl with a playful personality.
As with the monsters, Boo completely stole our hearts, as did the actress who played her, Mary Gibbs.
Mary was only 5 years old when she played the role. You can see pictures and a behind-the-scenes video of her below:
Mary Gibbs has grown up since and now works as a yoga teacher. As a sweet throwback to her iconic role, she made her Instagram username “yoga_boo” and on occasion even shares throwback pics from the Disney Pixar movie.
