|Old Man Prisoner|
|Name||Old Man Prisoner|
|Introduced in||"Gut Grinder"|
Old Man Prisoner is a character seen in "Gut Grinder." He was being held prisoner by the Spiky People when Jake was thrown in jail. It is unknown why the Old Man Prisoner was in jail, but he claims that it is for the "free grub." He then grabs a grub from the floor and sticks it in his nearly toothless mouth and starts laughing. The grub looks annoyed rather than terrified, so the Old Man Prisoner may have meant grub literally with reference to the one in the cell. Finn takes the Old Man Prisoner's only tooth, a false gold tooth, to lure the Gut Grinder.
He petted Jake while repeatedly calling him the Gut Grinder, putting Jake in a trance-like state that makes Jake believe he is the real Gut Grinder.
He looks like an old man but with a grayish skin and a hunchback. He appears to have many wrinkles in his body because of his oldness. He also wears a grey, torn shirt, and black torn shorts.
I'm in jail and I'm not the Gut Grinder. I'm here for the free grub.
Aww Gut Grinder... Aww Gut Grinder. You're a lil' cutesie, a lil' cutesie wutesie.
