Old Man

The Old Man makes his appearance in the Adventure Time short where he gets his diamonds stolen by Ninjas in the last scene. The Old Man might have a collection of diamonds. Pendleton Ward himself said that the Old Man was going to make another appearance, though the nature of the episode in which he will appear has not been revealed yet. He wears khaki shorts, has a white beard, blue shoes, and a yellow shirt with polka-dots.

It is unknown if the old man is human or not. He has the appearance of a normal elder human, and wears normal human clothes. This would mean that the only confirmed humans are Finn, Fionna, The Old Man, possibly Susan Strong, and possibly the Businessmen from the episode "Business Time".
