The Sea Dragon lunged up and down, wrinkling his nose like crazy and bellowing.

海龙冲上冲下，疯狂地皱着鼻子，咆哮着。

The Sea Dragon is the most well-defended creature that has ever lived on this planet.

海龙是这个星球上有史以来防御最严密的生物。

When Hiccup was hanging in the Sea Dragon's throat, desperately repeating " I need to live, I need to live" to himself, he had taken off his helmet and had plugged the horns as hard as he could into the fireholes.

当卡嗝挂在海龙的喉咙上，拼命地对自己重复着" 我需要活着，我需要活着" 的时候，他已经摘下了头盔，尽其所能地把角塞进了火洞。
