About this sound
Woody, Buzz and Jessie scream together in one loud, overlapping burst, three familiar voices rising at once as if something has gone badly wrong. It feels panicked and chaotic, yet funny because the alarm is shared, turning a small disaster into a moment everyone reacts to together. The clip comes from Toy Story, where the three friends often face trouble side by side.
