what do you think about the second movie script of HTTYD ?

I think it will be more like the book. They train to be a pirate. They find the coffin. They go to the island. All that stuff.

I think either Astrid or Toothless will be kidnapped or in some kind of trouble, and Hiccup has to cross the ocean to save her/him, with the help of his friends. but the adults either don't know about it or they think saving Astrid/Toothless would be a lost cause, so they give up. That's why the kids have to hijack a ship and sail to England or somewhere where Astrid/Toothless is being held hostage.
I think it should be Toothless.
Yeah, I really thought this out.

I think they'll stick to books' basic storyline but change a lot of things like in the first movie.

1.I think that toothless should find a girlfriend and Hiccup would get angry at him because he spends more time with her than with Hiccup, then toothless gets in to trouble and Hiccup is still a little angry at him but still has to save him.
2.The village is attacked by some evil dragons and all of the kids have to save it =D

i have the read the second book so i think that there is going to be a new character named alvin i hope they are going to put the bit where stoick freaks out and the part where a ship sinks and hiccup is under it and go down to the bottom of the sea that part scared me. and in all the books toothless comes to the rescue. there is probably going to be a big monster that eats one of the characters (not saying because they might put that part in)but for this film to work hiccup is gonna need to know how to speak dragonese

I don't think Hiccup will be speaking Dragonese, because Toothless fully understands when Hiccup talks to him.
