The end credit scene of the live-action film "How to Train Your Dragon" is very brief and symbolic. After the full credits roll, there is a short scene where Hiccup opens the Book of Dragons to the blank page for the Night Fury dragon. He places his personal notebook, which contains his detailed drawing of Toothless, on top of the Book. He then taps his fingers a couple of times on the page before the scene ends. This moment was already shown in the film but is isolated here as a quiet, meaningful moment rather than a teaser for a sequel. There is no new action or dialogue, and it does not reveal anything new about future storylines but hints at Hiccup's ongoing journey of documenting dragons.

So, the credit scene is short, more symbolic than plot-revealing, and appears at the very end of the credits. Staying through the credits shows some beautiful location shots and artwork of dragons, but the actual post-credit scene is just this quiet, reflective moment involving Hiccup and his drawings of Toothless.
