Hansel is a homeless man who debuted in Mario's Hobo Problem!. He frequently calls Mario, "Cheeseburger Man" due to giving him a cheeseburger when he asked for his twenty dollars and a burger. He seems to believe in aliens as shown in The Alien!.
The puppet used for Hansel is unknown, most likely custom made.
Hansel Is a homeless alcoholic who lives on the street and eats garbage, but don't let this fool you. Hansel isn't homeless because he got fired from his job, or didn't pay the bills, he became homeless because he is was too lazy to do either one. He thinks he can just get money if he makes people feel bad for him, and never bothers taking in a job offer. Even if he did get a job and money, all he would ever do is spend it on booze. He may say Mario is his friend, but all he does is mooch off of him like Black Yoshi, and would happily frame him for hitting him with the slightest tap if it means he would get more money.
According to some fans, he had a more Victor Caroli-esque quality to his voice, sounding closer to the equally dark villain, Tirek, from G1 My Little Pony.
Many people believed that he was Jeffy's Dad, but this is not true.
