Corrected entry: When Hiccup draws Toothless in the glen for the first time, he smudges the left tail section, indicating his understanding of the problem of why Toothless can't fly. When we next see the drawing, at dinner that night, the left tail section is clear and unsmudged. (And later in the film, it's smudged again.) Even if the filmmakers "fixed" this error while still in theaters, the DVD version I have shows the original errors - smudge/no smudge/smudge.

Correction: I have the DVD of the movie. And at the dinner table when Hiccup places the drawing on the dragon manual, the smudge is shown there.

Correction: This has been fixed. The tail IS smudged at the dinner scene.Apparently it was fixed whilst still in theaters.
