Did anyone else have horrific and graphic nightmares about being sold into the Viking slave trade because their older sibling decided one night that it'd be funny to read the 7th httyd book to them because they thought it'd be funny or is that just me?
In the beginning of the first httyd book Hiccup says "They are crawling back into the sea from whence they came, leaving not a bone, not a fang, in the earth for the men of the future to remember them by." Referring to the dragons and it's cool because that's what he said in the end of the third movie :)
