[TOMT] Help with finding old cartoon.
So, the show had dragon mentioned like a legend. But start the show with a young girl of the main characters playing a flute (or pan flute) with a song that the dragon which appeared (?, memory of this was fuzzy) recognized the song she played.
They are some kind of a farm family, with both parents, two boys, a crippled sister with a walking stick who played the flute and a pet.
Their town was over taken and ruled by violent creature that find taste in all disgusting stuff to human.
Spoiler: their family line is somehow related to the last overthrown kingdom ruler, and the kids are the "gem" the big bad is after.
Extra:
The pet turned big enough to carry people by secret vault potion of their lineage
an outcast character who dwell in forest with sock covered arms (red and white stripes)
the brothers got separated from the family when they're on the run, then again the brothers are separated from each other again. With one of them taken to a industrialized london like child labor factory.
