F-man is a hacker, who yes, I have met at various times. F-man hacks your account when you're not online, and then sells everything. The thing is, you don't get any gems, because he'll blow them in the claw. But, if he finds something he likes, he'll steal it for his real/non hacking account. He is a dark purple penguin with a white belly, and usually is seen standing still, which means he is hacking the games source code for everyone's passwords in that area (Ex. If you're in Kimbara Outback in Aldan with him, he can find your password). And, finally, he'll change your animals looks. They'll be pitch black with dark red eyes. He has many "friends", which are just smaller F-men.
