This was the best show ever when I was 8 i loved it I would go out Maude and pretend to be hiccup riding toothless I wish I could go back to those days and not have the drama I have now 😢
My guess on how Hiccup lost his leg, is that Toothless had to pull him closer to him, but in doing so, he bit his leg off, cause of adrenaline and being a Dragon, he probably used to much strength and bit it off
