Boulderwood is a 33-year-old teacher of White English Canadian heritage. He has brown hair and dark grey eyes. He wears a dark grey suit with a white-and-silver striped tie, and he is nearly always seen carrying around a suitcase, just like the protagonists of the show Dartmouth and Jollimore. He is Rockingham's twin brother, and the two are often seen together.
- Boulderwood may have been so named because of his twin brother Rockingham; a rock is a small boulder.
