About this sound
This clip is a snarling zombie baby growl, a high-pitched monster snarl stretched over about five seconds of gurgles and raspy snarls. It feels creepy and funny at the same time, because the voice sounds small and helpless until the growl takes over and makes the moment feel feral and unsettling.
