The sound design of Monsters, Inc. by Gary Rydstrom and Tom Myers gave the monster world its playful, larger-than-life personality. Every creature had a distinct sonic identity—Sulley’s footsteps were heavy but soft to match his size and warmth, while Mike’s lighter, quicker movements highlighted his fast-paced, comedic energy. The roars throughout the film were carefully balanced, blending animal growls, pitched-down voices, and cartoon-like exaggeration so they felt scary enough for the story
