Frankie is quite the basketcase around the track. They are skilled in designing and fixing cars, yet they also use that skill to fix furbies and different toys. They also love to draw, and often draw people and objects around the track just for fun. Mr.Carbuerettor likes these drawings and uses their art (with Frankie's position) to post around Silverhatch and various advertising. That aside, Frankie's an avid collector of furbies, pins, Nintendo merchandise, and comic books. They're a massive Mario fan and likes to play N64 and Wii games when not working. Another hobby of theirs is gardening, they have a small garden in Silverhatch they take care of quite often. They grow flowers and fruits, selling them at the farmer's market to make extra money.

Frankie is dating Marsha and Big Chris in a polyamorous relationship, often spending time around the track on break. They keep it professional while on the clock, with some exceptions when they tease and show affection. Frankie spends more time with Big Chris as his assistant, but they do often visit Marsha while she's working. When there's nothing to do, it's not uncommon that Chris, Marsha, and Frankie all chill out in the garage and watch Frankie play with their gameboy or simply make conversation with the cars. Frankie isn't one to be a social butterfly, but when Marsha and/or Chris are around they open up a bit more.

Frankie is an avid music lover. They can sing and play guitar, a passion shared with Chris. Marsha isn't all that into music, but she doesn't mind sitting and listening to Frankie play a song while Chris sings along. Frankie's favorite genre is punk rock, and they've memorized lots of Green Day and Outcast songs to make a 34 hour playlist. However, Frankie's biggest income is their job, and guitar-playing and singing are simply hobbies they do for fun.
