at least it's not brookhaven, am i right
This role can be done by anyone who can make a noise.
The noise in question should preferably sound like that of one of Krang's burps (from the 80s TMNT cartoon, I believe) and a roar of a velociraptor combined. Whatever sound you make, it should sound like it'd be menacing at night and completely non-menacing in any other context.
There are a few other animalistic sounds that I would like if you could do as well, listed in the audition lines
