Prince Dax is King Turgon's son, and is assumed to be a few years younger than Peewit. He is a strong-headed child with a habit of causing mischief that others end up taking the blame for.
He only appeared in "Peewit Meets Bigmouth" in Season 3 of the Smurfs cartoon show when his father signed a peace treaty between his and The King's kingdom. He turned himself into a chicken while mishandling one of Peewit's spell cauldrons and was nearly eaten by Bigmouth when he escaped the castle and ran into the forest. If it were not for the help of Peewit and the Smurfs, he would not have survived.
By the end of the episode, he is returned to normal and does not remember being a chicken -- only that he went on an adventure and Peewit saved him.
He is voiced by Katie Leigh.
