Banana is a little robot made of an obsolete computer monitor and tower, as well as 2 legs and an arm. He can only be communicated with verbally through command prompts compatible with Windows 95, and can only respond in kind. Because of this, most of what he says is "Bad command or file name"
His screen is usually black, static, or white text on black (because his owner does not know how to work computers as obsolete as his system and is having trouble figuring out the software oops).
He obviously has emotions, but it is hard to understand his thinking due to his inability to communicate.
He has very good balance, and owns an array of floppy drives which he leafs through when he gets bored.
