Stupidity: During one of the test drives, the hook that Hiccup uses to fasten himself to Toothless gets bent, so he takes Toothless to the blacksmith to cut the line. There are two ways he could have easily avoided this: He could just unhook the saddle, take that to the blacksmith and cut himself loose, or he could just untie the leather strap. What he does here is needlessly risky and just there for his awkward conversation with Astrid.

How to Train Your Dragon (2010)

Directed by: Chris Sanders, Dean DeBlois
Starring: Gerard Butler, Jonah Hill, Jay Baruchel, America Ferrera, Christopher Mintz-Plasse, Craig Ferguson
Plot hole: When Astrid gets on Toothless for the first time, Toothless takes off uncontrollably and tries to scare her. Hiccup seems to have no control over him at this time. How is that so if with the new tail fin, Toothless cannot fly without Hiccup's precise control of the tail fin? That whole sequence would have fallen apart. This mistake was even admitted to on the DVD commentary. (00:53:35)
Question: What is the gender of the giant dragon? Astrid refers to it as the Queen, but Hiccup calls it a he and him several times in their battle with it. The movie is not clear if the dragon is male or female, and the sites I searched about it were just as cryptic. So what is the gender of the giant dragon?

Chosen answer: It is never mentioned. but Astrid only used the term queen as a reference to ants' or bees' hive minds, so as it's referred to as a he every other time, we can assume it's male.

Well this was answered in the second film by Hiccup's mother. "Every nest has its Queen... but this is their king!" when she refers to the Alpha, which is a bigger and different dragon than the one in the first film. In this context, the dragon in Part 1 is a Queen, therefore female.
