Ok I Just Watched "The Sea Beast" And

Ok I just watched "The Sea Beast" and

-------SPOILERS------

[Cause Idk how to do the cut thing yet lol]

--------------------------

I have a few questions

What was that manta beast at the beginning of the film? Was it ever hunted down or is it still out there?

What is the whole Hunter Code? I know we get some bits and pieces if it, but holy cow I wasn't expecting "Kill a crew member who's being a coward" to be on there, especially when there's no exceptions to kids.

What's going to happen to Crow?

He's quite literally lost everything. What is he going to do now? I don't think he went back to the crew and was like, "Yeah I tried to kill a child and my own adopted son and did some black market dealing but that was like, 10 minutes ago!" And everyone was fine with it.

So that Batterbie? Batterby? However you spell it. Is she like a sea witch or something?

Like HTTYD, will there be a follow up movie/show? Cause it sure does feel like it to me.
