Jimmy Gablonski is a recurring character in the High School Years and Forever Sophomores series. He is a classmate of Tom and the gang and Willy's former partner-in-crime. In Freshman Year, he was in every single one of their classes, except Literacy, Biology, and Art. In Sophomore Year, he's in their US History class.
Jimmy is a calm and mellow guy. He often acts neutral in Willy's arguments with the guys. In Season 18, Willy used to mock him, but later in the season, they became close friends. That was, until "Uncle Funtime: Thanksgiving Edition", when Trent slapped Anthony in the face for shutting down his Chromebook. Willy told Anthony that he wouldn't call him "Padilla" anymore if he didn't tell anyone. This caused Jimmy to break up with Willy, because he actually liked the nickname "Padilla". Despite not being partners-in-crime anymore, Jimmy and Willy remain good friends, even though Nathan tries to tear them apart often.
Jimmy has fair skin, blue eyes, and light brown hair. His outfits vary throughout the series, but he is often seen in 2 outfits. His first outfit consists of a blue long-sleeved shirt, khaki shorts, and black sneakers. His second outfit consists of a black and white jacket over his blue shirt, brown khakis, and white sneakers. Sometimes, he wears a different color hoodie, different color shirt, and lighter or darker khakis. In Seasons 19-20, he wears crutches after an accident in football.
