|“||UNCLE PAUL! EDWARD JUST SET YOUR VALUABLE TROPHIES ON FIRE!||”|
Sid is a mischievous eight-year-old who has no respect for authority figures. Whenever he's around adults, he pretends to be a "goody two-shoes", but when there's no adults in sight, it's an entirely different story. He enjoys pulling off life-threatening pranks, especially to Edward and Eric. Whenever he's with the brothers, he always go great lengths to get them in trouble by the end of the episode.
- He is a parody of Bart Simpson from the longrunning animated series, The Simpsons. To some extent, he is also based on Kevin McCallister from the Home Alone franchise and Dennis the Menace from the namesake comic book series (the British version of it, at least).
- In fact, Sid's most favorite food is the popular chocolate bar, Boogerfinger.
- Series creator Gary Sauls has openly stated that Sid is based on two of his younger cousins; the both of them happen to be siblings. He described them as "hell on Earth".
- Much like the brothers' other cousins, Sid looks almost exactly like Edward.
