Stuart is an obnoxious and snobbish man, he doesn't seem to try very hard in dilemmas. He seems to be somewhat clumsy as well since he broke the urn which contained Herb's ashes.
His intelligence is also questionable as he doesn't seem to catch on that having the opposite half of the medallion that Tracy has means she is his twin sister despite almost being exactly alike in every way.
Stuart is an adult human man with curly brown hair, thick brown eyebrows, and freckles on his cheeks, and a pair of thin-framed rectangular glasses. He has a slight resemblance to Tracy, the adoption caseworker who could possibly be his long-lost twin sister.
According to the model sheets, he is 5 1/2 ft tall.
He wears a lilac collared button-down shirt with a white floral print, a thin deep purple necktie, dark brown belt with silver buckle, light brown dress pants and maroon loafers. Under his shirt, he wears the right half of a medallion with his family's crest on it.
Stuart was Laura's replacement as Princess Carolyn's assistant in Season 2 until he was replaced by Judah Mannowdog in Season 3. After Judah was fired in the Season 4 episode Ruthie, Stuart became Princess Carolyn's assistant again.
- Tracy (twin sister; though unlikely they ever caught on)
