"Speaking an uncommon Scottish dialect that is incomprehensible to most, Young MacGuffin is a shy lad of large proportions. Being the center of attention is not his strong suit, but he will not hesitate to leap into a fight alongside his father and clan when the occasion arises."
- Kevin McKidd voiced Young MacGuffin using the Doric dialect of Scots (not English) from his native area.
- Young MacGuffin was to be the suitor that Merida chooses in the initial version of the film (hence his name), but this idea was later changed. In the final version, it's explicitly stated that Merida does not want to marry at all, and ultimately remains single by the end of the film.
