Justin is a character who appeared in the cartoon show episode "To Smurf A Thief." He is a young boy who originally lived as a street urchin by the name of Tipper, working for his thieving guardian named Shedlock. Unfortunately, when Tipper stole Homnibus' handbag while in the marketplace, he was caught with Shedlock by the magistrate and sentenced to life in prison. However, Homnibus refused to testify on his behalf since his handbag was returned and Tipper pleaded that he did not want to become a criminal; it was merely his guardian who had control over him.
After Homnibus agreed to adopt him, he had his name changed to Justin and became enrolled in school so he could start a new path leading to a fulfilling future. He had some bumps in the road (being accused of stealing again only to be proven innocent by his caretaker), but has progressively proven himself to be both humble and inquisitive.
