Whilst re-listening to the whole thing over again from the start I noticed that Ink has influence over animals too....

Within part 3 of chapter 13, "Separate dying embers" at around 8 minutes a 50 seconds after Ink lets out a roar to his minions around the tower and fire truck, you can make out the distinct cry of an elephant!!! please go and check this out its definitely and elephant!

Now I'm not sure if this is an oversight from the sound editors or just a little light hearted fun from KC, but either way it was funny to hear amongst the usual groans and grunts we hear from the regular biters doing Ink's dirty work.

This isn't really a thread to be continued or an alternate theory but just something I felt was worth motioning. lol.
