This is first mentioned by Doug when he is telling Mal, Evie, Jay and Carlos that he had put in core requirements. While it is a core requirement at Auradon Prep the course or even some variant would most likely not appear as a core requirement at Dragon Hall (the school Mal, Evie, Jay and Carlos transferred from). For Mal, the course is her first and Jay and Evie's sixth (all notwithstanding Remedial Goodness 101) and once again unlisted as towards which number class it is for Carlos. It is unclear whether there is a story that involves Woodsman however the Pirates may be a reference to Captain Hook from Peter Pan.
