Foop is very rebellious and likes to annoy his grandfather immensley. Most of his family members annoy him, including his uncle, Sanderson, and his younger sister, Anti-Rosemary. Often without his father's consent, he joins him and his grandfather on their adventures, sometimes helping, sometimes just being a nuisance. Foop acts like he knows everything, but in reality, can be very clueless when it comes to certian situations.
Foop started developing a crush on his younger adopted cousin, Sidney, around his early teen years. At first, she was oblivious to his advances, but later caught on, being repulsed at first, then comming to terms with it, and finally, going along with it. They start to go out when they reach their later teens.
