not sure if i have any good names for the species but you need a named one, colored purple, and call it Coily muhahahaahah
if your sound guy wanted to have some fun..would be fun to have the snake make different noises than just a standard snake hiss/rattle.
The Giggle Rattle (makes childlike giggling noises)
The Clatter Rattle (loud clattering board noises)
The Splatter Rattle (wet smushy noises)
The Cattle Rattle (deceptive, sounds like mooing)
The Battle Rattle (rattle aking to war drums and the hiss sounds like a bugle)
The Fattle Rattle (sounds like an out of shape person trying to chase the ice cream truck)
The Maddle Rattle (indiscernible angry grumbling sounds like yosimete sam or some Wren from wren n stimpy)
The Shattle Rattle (Kind of a crappy name.. best not describe this..you get the drift)
The Kittle Rattle (hiss is a cat's meow, rattle itself sounds like loud cat purring)
Ok so NONE o fthese will get used.. but it was damn fun coming up with them.
