Mr. Sserpent's video: How To Train Your Dragon: The Hidden World - Deathgrippers Sound Effects

Al Nelson: There were new dragons that were the minions of Grimmel. Those were called Deathgrippers. Their visual design gave us the opportunity to do something new and cool. Randy and Jeremy were involved in the initial vocalizations, and those were great. The director Dean then gave them the note that he wanted the dragons to do this clicking sound, which reminded me of the Predator alien sound. So Randy comes back with something a few hours later and it’s this really cool, liquidy, clicky, goopy sinister sound. I had the privilege of going back through and adding that in under the vocalizations. So when we first meet these evil dragons, the Deathgrippers, they come walking past and you hear them coming in from the surrounds. It’s creepy! It’s really fun. Randy Thom: The fun thing about these Dragon movies is that there are always new dragons that you haven’t seen before. Trying to come up with the sounds for the new dragons is a kick. For the acid goop, one thing that I recorded was pouring liquid from one very hot pot or frying pan into another so that you get this dynamic sizzle. The main trick there is to choose raw material that has the most potential to make an interesting sound. And so since this acid goop is coming out of the mouths of the dragons, I found that using pots with a fairly narrow opening at the top (or metal containers with a fairly narrow opening at the top) more closely simulated the sound of a vocal cavity, i.e., a mouth. That way the sizzling sounds and the airy sounds of pouring liquid from one container to another became more musical and more dynamic and more like a vocal.
