Muff Potter is the town drunk.
He showed maturity when he tells the truth in the court case with muff potter.
He brought him tobacco and matches while he was in jail and then testified in court for him.
In Mark Twain's book The Adventures of Huckleberry Finn, the three men that Tom and Huck hear in the graveyard are Dr. Robinson, Injun Joe, and Muff Potter. Injun Joe murders Dr. Robinson and blames it on a drunk Muff Porter.

Injun Joe is a Native American outlaw in "The Adventures of Tom Sawyer" who is the main antagonist of the story. Muff Potter is a drunkard and town drunk who is falsely accused of murder by Injun Joe. Dr. Robinson is the town doctor who examines the body of the murder victim and provides key evidence in the case.
Tom took food, like pies and other treats, to Muff Potter when he was in jail. He also brought Muff a note from Huck Finn saying he wanted to help.
In "The Adventures of Tom Sawyer" by Mark Twain, Muff Potter is first blamed for the murder of Doctor Robinson. Tom Sawyer and Huckleberry Finn witness the murder but are initially too scared to come forward as witnesses.

Tom felt bad for Muff Potter because he had witnessed Muff being framed for murder by Injun Joe. Tom wanted to feel like he was giving back to Muff in order to cover up his guilt for keeping quiet about Injun Joe. That's all I'm going to say, since I'm assuming that you are asking a question directly from your reading homework. :)
Muff Potter is initially shocked and denies being involved in Dr. Robinson's death. He is confused and frightened by the accusations, but eventually confesses after feeling guilty about the incident.
