None, except from when Hiccup asks Gobber to take off his pants for a reason.

Brief animated violence.

None.

None.

The brief violence in this film is basically nothing, compared to what is seen in the TV-series "Dragons" and the theatrical movies. However, some very small children may find the Boneknapper dragon to look a bit frightening.

This short animation would probably have been rated PG if it was to be submitted to MPAA.
