Place this clip right at the reveal in a fail edit, after a danger alarm sound effect sets up the trouble and just before a run vine effect sound carries the escape, so the sequence moves from warning to reaction to getaway without extra effects in between.
Über diesen Sound
An under-one-second scared squeal from Ross, the freckled pig builder in Bad Piggies, this clip is a quick high-pitched yelp of panic. It lands as funny and startled rather than truly frightening, giving a small moment of cartoon fear that reads instantly as something going wrong just before a contraption collapses or a plan falls apart.
