Place it immediately after the surprise in a short edit, with Metal Gear Alert just before it to set up the scare, then Woody Woodpecker Laugh straight after it to close the sequence and keep the scene moving.
Über diesen Sound
A brief, high-pitched squeak from Truvius, lasting under a second, captures the instant he is caught off guard. It sounds small, shaky and suddenly startled, like a nervous gasp squeezed into a single squeak. The effect is comic and awkward, turning a moment of fright into something listeners can laugh at rather than worry about.
