Put it after the Metal Gear Alert Sound and before the SpongeBob Sad Song, so the edit moves from a warning signal to this admission and then to a comic ending.
About this sound
This is a short voice clip of about five seconds from the Chilean puppet show 31 Minutos, in which a character says tengo miedo, Spanish for I am scared. The voice is small and nervous, giving the moment a tense, frightened feeling that still feels funny because it comes from a puppet. It works as a comic admission of fear rather than a serious cry for help.
