Well, as I understand it, in the book this visual oddity was
a side-effect of them using frog DNA to patch the holes in the
recovered DNA. (Bleah - what a stupid choice - crocs would have
been a much better choice).

This, however, I will agree with. (#2 is even quite likely,
though it would likely be a different sound than #1).
Note, an animal confronted with something unusual can get confused
about categories - I know of animals that tend to react to humans
as potential rivals (i.e. as if we were other males of their species).
Still, Holywood would tend to want lots of impressive noises,
which means lots of belowing.
The peace of God be with you.
