If a giant Godzilla-esque monster were lurking in US waters...?

Question

Who would be the first to notice, or do anything about it?

I ask this question because I am writing a novel, -partially- about how different people react to such an outbreak of alien monster attacks. The other parts are just regular drama, as well as how different people deal with each other under pressure (they find ways to get on each other's nerves, even when in the background Godzilla is rampaging). Yes, it's meant to be satire.

BTW, if it helps, the characters, who all eventually realize that the giant monster exists consist of-

-Two characters in the military (different specialities/jobs and different branches though, but both are sent to absolute, depressing sh*tholes)
-A college kid who spends the first half of the novel trying to reclaim her collection of misplaced shaving razors,
-A desperate housewife
-A shrewd, seemingly robotic businessman who doubles as a glitter-queen male stripper
-A guy who does air traffic control
-An out-of-work stoner who's writing "the dest bamn opera ever" while living in his brother's basement.
-A lawyer and her four-year old niece, who are probably the sanest characters in the entire batch.

Answer 1

The navy would have found it on there radars, make it attack a sumbmarine

Answer 2

Someone in the fishing industry. A giant, Godzilla-esque monster eats alot.

Answer 3

You should make the first people to notice the weirdest characters, that way people think they are indeed crazy, until out of nowhere the little girl goes "Look auntie, look at the big alligator in the water" and tada...the rest is up to you.

Answer 4

Well, what I would do is buy stock in rubber cement companys. They're going to need every bit of rubber cement they can get to glue down that giant stunt man in the rubber Godzilla suit.

Answer 5

I think the opera stoner should notice first! That would be funny, as no one would believe him, as he probably says rediculous things all the time.
