Many of his strips parallel a storyline in the corresponding Freak Brothers story, and often have themes of a scatological nature. He has several "nephews" who refer to him as "Uncle F." and sometimes finds himself confronting an organized army of cockroaches or a huge tribe of mice who share the apartment with the Freak Brothers. He is far smarter than his owner (whom he frequently refers to as "the obese one") and regards the Freak Brothers with amused contempt, sometimes using their headphones as a litter box.
