Oscar isn't very confident with his appearance. He's constantly on a diet and at the same time feels that he's too short for his age. Although his friends think he's an ok guy, he seldom goes out to play with them and would rather stay in his room and read comics.
Oscar is only 4cm tall (a little over 1.5 inches). His nose is also slightly crooked to his left.
Oscar has been adopted and moved out of the farm.
